[0010] The present disclosure will be described below based on preferred embodiments with reference to the drawings. The embodiments are illustrative and do not limit the disclosure, and all features and combinations described in the embodiments are not necessarily essential to the disclosure. The same or equivalent components, parts, and processes shown in each drawing will be designated by the same reference numerals, and redundant descriptions will be omitted as appropriate.

[0011] 1 and 2 are schematic diagrams showing a sheet decoration system 10. Fig. 1 is a side view, and Fig. 2 is a plan view. The sheet decoration system 10 is a system that applies a predetermined decoration to a sheet while transporting the sheet. The sheet material can be various, such as paper, cloth, resin, or metal.

[0012] Hereinafter, the direction in which the sheet is transported (the direction from right to left in Figures 1 and 2) will be referred to as the transport direction Y, and the direction perpendicular to the transport direction Y (the direction perpendicular to the paper surface in Figure 1 and the up-and-down direction in Figure 2) will be referred to as the width direction X.

[0013] The sheet decoration system 10 includes a feeding device 12 that feeds sheets one by one, a varnishing device 14 that applies ultraviolet-curable varnish (hereinafter simply referred to as "varnish") to the sheets fed one by one and irradiates the varnish with ultraviolet light, a transfer device (foil stamping device) 16 that transfers a foil, which is a transfer material, to the varnish applied to the sheet by utilizing the tackiness of the semi-cured varnish, a stacker 18 that accumulates sheets, and a control device 20 that provides overall control of the sheet decoration system 10. The feeding device 12, varnishing device 14, transfer device 16, and stacker 18 are arranged in a line in this order from the upstream side (the right side in Figures 1 and 2) to the downstream side in the conveyance direction Y. The control device 20 is connected to the feeding device 12, varnishing device 14, and transfer device 16 via a network 2.

[0014] The feeding device 12 includes a feeder 22, a corona treatment unit 26, and a registration unit 24. The feeder 22 includes a table 28 and a suction head 30. Sheets are stacked on the table 28. The table 28 is configured to be able to move up and down. The suction head 30 feeds the sheets stacked on the table 28 one by one in order from the top.

[0015] The corona treatment unit (surface modification unit) 26 includes an electrode (applying electrode) 36 disposed above the conveyance path 34 and a dielectric roller (counter electrode) 38 disposed below the conveyance path 34 so as to vertically oppose the electrode 36. The corona treatment unit 26 performs surface modification on the sheet delivered by the feeder 22 by corona discharge between the electrode 36 and the dielectric roller 38. Specifically, hydrophilic groups are generated on the surface of the sheet, improving wettability. Note that when the sheet is conveyed while being attracted to the conveyance path 34 by the air suction unit 40, the distance between the electrode 36 and the sheet becomes constant, stabilizing the corona discharge. The air suction unit 40 generates negative pressure by arranging one of the suction ports of an exhaust blower (not shown), but it may also be configured to generate negative pressure by arranging a suction fan.

[0016] The registration unit 24 aligns the position in the width direction X of the sheet fed by the feeder 22 by abutting against the registration reference guide 32.

[0017] The varnish application device 14 includes a sheet sensor 42, at least one (three in FIG. 2) varnish application section 46, a semi-curing ultraviolet irradiation section 48, and a final curing ultraviolet irradiation section 50. The sheet sensor 42, varnish application section 46, semi-curing ultraviolet irradiation section 48, and final curing ultraviolet irradiation section 50 are provided in this order from upstream to downstream.

[0018] The sheet sensor 42 detects the sheet fed from the feeding device 12 .

[0019] There is no particular limitation on the number of varnish application units 46. The varnish application device 14 may include one varnish application unit 46 extending over the range in the width direction X over which varnish needs to be dispensed or over a wider range, or may include two or four or more varnish application units 46.

[0020] The varnish application unit 46 is a line-type inkjet head, although not particularly limited thereto. Under the control of the control device 20, the varnish application unit 46 ejects varnish according to the varnish application data, triggered by the detection of the sheet by the sheet sensor 42, and applies the varnish to the sheet. The varnish application data is data indicating the area on the sheet to be varnished. The area to be varnished may have a predetermined relationship with the base image.

[0021] The ultraviolet irradiation units 48, 50 irradiate ultraviolet light under the control of the control device 20. Typically, LEDs (Light Emitting Diodes) are used as the light sources of the ultraviolet irradiation units 48, 50, but other light sources such as incandescent lamps or fluorescent lamps may be used as long as they irradiate ultraviolet light. The light sources of the ultraviolet irradiation units 48, 50 are capable of adjusting the ultraviolet irradiation intensity of the ultraviolet light they irradiate. The ultraviolet irradiation intensity may be adjusted, for example, by adjusting the drive current applied to the light source. When an LED is used, analog dimming by adjusting a variable resistor or PWM dimming by adjusting the duty ratio may be used.

[0022] The semi-curing ultraviolet irradiation unit 48 irradiates the varnish on the sheet with relatively weak ultraviolet light to semi-cure the varnish. Semi-curing refers to curing the varnish to a degree that reduces its fluidity but does not completely harden it, for example, to a state where it can be further hardened. The semi-cured varnish is then fully cured in the transfer device 16. Full curing refers to fully hardening the varnish. When foil is not being transferred to the sheet, the semi-curing ultraviolet irradiation unit 48 is usually turned off. Note that the semi-curing ultraviolet irradiation unit 48 may also be used when foil is not being transferred to the sheet. For example, if the varnish applied to the sheet is prone to bleeding, the semi-curing ultraviolet irradiation unit 48 is turned on to semi-cure at least the surface of the varnish. This prevents the varnish from bleeding.

[0023] The final curing ultraviolet irradiation unit 50 irradiates ultraviolet rays onto the varnish applied to the sheet, thereby final curing the varnish. When transferring foil onto the sheet, the final curing ultraviolet irradiation unit 50 is turned off.

[0024] That is, when transferring foil to a sheet, the varnish is semi-cured by the semi-curing ultraviolet irradiation unit 48, and the semi-cured varnish is then fully cured by the transfer ultraviolet irradiation unit 66 of the transfer device 16. In this case, the fully curing ultraviolet irradiation unit 50 is turned off.

[0025] If foil is not to be transferred to the sheet, i.e., if varnish is only to be applied to the sheet, the varnish is fully cured in the full-curing ultraviolet irradiation unit 50. In this case, the semi-curing ultraviolet irradiation unit 48 and the transfer ultraviolet irradiation unit 66 of the transfer device 16 are turned off. Note that, as mentioned above, the semi-curing ultraviolet irradiation unit 48 may be turned on even if foil is not to be transferred.

[0026] The transfer device 16 transports the sheet and also transports the web (transfer web) 52 roll-to-roll, bringing them into contact. In other words, the web being transported roll-to-roll contacts the sheet being transported. As a result, the foil held by the web 52 adheres to the semi-cured varnish on the sheet. In this state, that is, in a state in which the foil is held by the web 52 but also adheres to the semi-cured varnish, the transfer ultraviolet irradiation unit 66 irradiates the semi-cured varnish with ultraviolet light, fully curing the varnish. Once the varnish is fully cured, the adhesive force of the foil to the varnish becomes stronger than the force with which the web 52 holds the foil. In this state, when the sheet is transported and the sheet and web 52 are separated, the foil held by the web 52 is transferred to the varnish on the sheet.

[0027] The transfer ultraviolet irradiation unit 66 irradiates ultraviolet rays under the control of the control device 20. As with the ultraviolet irradiation units 48 and 50, the light source of the transfer ultraviolet irradiation unit 66 typically uses an LED (Light Emitting Diode), but other light sources such as an incandescent lamp or fluorescent lamp may be used as long as they irradiate ultraviolet rays. The light source of the transfer ultraviolet irradiation unit 66 is capable of adjusting the ultraviolet irradiation intensity of the ultraviolet rays it irradiates.

[0028] The stacker 18 accumulates the sheets (decorative sheets) delivered from the transfer device 16.

[0029] The control device 20 controls the overall operation of the sheet decoration system 10. The control device 20 accepts input of job definitions. The control device 20 may display a predetermined job management screen and accept input of job definitions. The job definition may include, for example, the number of sheets to be decorated (number of sheets to be processed), the sheet size of the sheets to be decorated, and varnish dispensing data. The control device 20 controls the feeding device 12, the varnish application device 14, and the transfer device 16 based on the job definition.

[0030] The control device 20 is connected to an external server 200 via a network such as the Internet. The server 200 is managed by a manufacturer 202. The manufacturer 202 is a company that produces sheet decoration systems. Here, "managed by the manufacturer 202" includes not only cases where the manufacturer 202 manages it directly, but also cases where a company commissioned by the manufacturer 202 manages it.

[0031] The above is the overall configuration of the sheet decoration system 10.

[0032] As a modification, the sheet decoration system 10 may include a printing device that prints images on sheets instead of the feeding device 12, and the sheets may be fed one by one from the printing device.

[0033] The sheet decoration system 10 may also include other devices between the transfer device 16 and the stacker 18, such as a post-processing device.

[0034] Incidentally, (a) the ease with which a varnish hardens, i.e., the cumulative amount of ultraviolet light required to semi-cure or fully cure the varnish, differs for each type of varnish. For example, when semi-curing a varnish, if the cumulative amount of ultraviolet light irradiated on the varnish is too small, the varnish will not be semi-cured, whereas if the cumulative amount of ultraviolet light irradiated on the varnish is too large, the varnish will be fully cured.

[0035] Furthermore, (b) the desired degree of semi-curing, i.e., hardness, varies depending on the type of foil; some foils are better off semi-cured hard, while others are better off semi-cured softly. Specifically, the ease with which the foil peels from the web 52 varies depending on the type of foil, and therefore the degree of semi-curing, i.e., the degree of tackiness, required for the varnish varies depending on the type of foil. Therefore, even if the varnish is the same, the cumulative amount of ultraviolet light required to semi-cure the varnish differs depending on the type of foil. Furthermore, (c) for soft semi-curing, a greater cumulative amount of ultraviolet light is required for full curing than for hard semi-curing. In other words, even if the varnish is the same, the cumulative amount of ultraviolet light required to fully cure the varnish differs depending on the type of foil.

[0036] Furthermore, (d) the transmittance of ultraviolet light through foil varies depending on the type of foil. Therefore, even if the ultraviolet light irradiation intensity of the ultraviolet light irradiated by the transfer ultraviolet light irradiation unit 66 is the same, the cumulative amount of ultraviolet light irradiated onto the varnish will differ depending on the type of foil. If the cumulative amount of light is too small, the varnish will not fully harden, and if the cumulative amount of light is too large, the foil may be damaged.

[0037] The cumulative amount of ultraviolet light irradiated onto the varnish can be controlled by adjusting the ultraviolet irradiation intensity of the ultraviolet irradiation unit, which is one of the control items of the sheet decoration system 10. The higher the ultraviolet irradiation intensity, the greater the cumulative amount of ultraviolet light irradiated onto the varnish, and the lower the ultraviolet irradiation intensity, the less the cumulative amount of ultraviolet light irradiated onto the varnish. However, because it is necessary to take into account the above (a), (b), (c), or (d), adjusting the ultraviolet irradiation intensity is difficult and places a burden on the user.

[0038] Therefore, in this embodiment, the control device 20 stores the job results of past jobs (hereinafter referred to as past jobs) and, based on the job results of the past jobs, suggests candidates for ultraviolet irradiation intensity for the current job (hereinafter referred to as current job) that is about to be executed, thereby reducing the burden on the user.

[0039] 3 is a block diagram showing the functions and configuration of the control device 20. Each functional block shown here can be realized in terms of hardware by elements or mechanical devices such as a processor such as a computer's CPU (Central Processing Unit) and memories such as ROM (Read Only Memory) and RAM (Random Access Memory), and in terms of software by a computer program, etc. Therefore, it will be understood by those skilled in the art that these functional blocks can be realized in various forms using only hardware, only software, or a combination of both.

[0040] The control device 20 includes a communication unit 110, a data processing unit 120, and a data storage unit 140. The communication unit 110 communicates with other devices according to a predetermined communication protocol. The data processing unit 120 executes various types of data processing. The data storage unit 140 stores data referenced or updated by the data processing unit 120.

[0041] The data storage unit 140 includes a job performance information storage unit 142 and an ultraviolet irradiation intensity storage unit 144 .

[0042] FIG. 4 is a diagram showing an example of the data structure of the job performance information storage unit 142. The job performance information storage unit 142 stores performance data for past jobs. Specifically, the job performance information storage unit 142 stores adhesion-related information, which is information related to the adhesion between the varnish on the sheet and the transfer material to be transferred to the varnish on the sheet, in past jobs, in association with the ultraviolet irradiation intensity of the ultraviolet rays irradiated by the semi-curing ultraviolet irradiation unit 48 and the transfer ultraviolet irradiation unit 66, the number of sheets processed, and the execution date, i.e., the registration date. The job performance information storage unit 142 may also store the ultraviolet irradiation intensity of the ultraviolet rays irradiated by the main curing ultraviolet irradiation unit 50.

[0043] The adhesiveness-related information includes the type of varnish applied to the sheet, the type of foil when the foil is transferred onto the varnish, and whether or not the sheet is laminated. The type of varnish, for example, includes the model number of the varnish, as shown in the example of Figure 4. The type of foil, for example, includes the foil manufacturer, model number, and color of the foil, as shown in the example of Figure 4.

[0044] Lamination is a process performed before the application of varnish, in which a thin resin film is attached to the surface of a sheet. The applied varnish does not penetrate a laminated sheet. In other words, the photoinitiator contained in the varnish does not penetrate a laminated sheet either. Therefore, when a sheet is laminated, i.e., when lamination is present, a larger amount of photoinitiator remains in the varnish on the sheet than when the sheet is not laminated, i.e., when lamination is absent, the cumulative amount of ultraviolet light required to semi-cure or fully cure the varnish is smaller.

[0045] All of the information items in the adhesiveness-related information in this embodiment are information related to the varnish on the sheet. Therefore, in this embodiment, the adhesiveness-related information can also be considered as varnish-related information.

[0046] Returning to FIG. 3, the ultraviolet irradiation intensity storage unit 144 stores the value of the ultraviolet irradiation intensity of the ultraviolet light irradiated by the ultraviolet irradiation unit in the current job.

[0047] The data processing unit 120 includes an acquisition unit 122, a setting unit 124, a job execution unit 126, a registration unit 128, and a transmission unit 130.

[0048] The acquiring unit 122 refers to the job performance information storage unit 142 and acquires the value of the ultraviolet irradiation intensity of the past job from the performance information of the past job having adhesiveness-related information corresponding to the adhesiveness-related information of the current job.

[0049] In more detail, the acquisition unit 122 first acquires adhesiveness-related information for the current job. To this end, the acquisition unit 122 displays, for example, a setting screen, which will be described later in FIG. 5, on a predetermined display unit. The user inputs adhesiveness-related information into the setting screen. The acquisition unit 122 acquires the adhesiveness-related information input into the setting screen. Note that the acquisition unit 122 may acquire the type of varnish from an RFID tag attached to the varnish container via a reader (not shown).

[0050] Next, the acquisition unit 122 refers to the job performance information storage unit 142 and acquires the value of the ultraviolet irradiation intensity for the past job having adhesiveness-related information corresponding to the adhesiveness-related information of the current job.

[0051] Corresponding adhesive-related information means that the adhesive-related information matches, and in this embodiment, this means that the type of varnish, type of foil, and whether or not lamination is performed for the current job matches the type of varnish, type of foil, and whether or not lamination is performed for the previous job.

[0052] For example, if the information stored in the job performance information storage unit 142 is as shown in Figure 4, and the type of varnish in the adhesiveness-related information for the current job is "V001", the foil manufacturer, model number, and color are "AAA, F123, gold", and whether or not lamination is performed is "no", the values ​​of the ultraviolet irradiation intensity for the job performance with IDs "0004", "0005", and "0006" are obtained.

[0053] As a variant, "adhesion-related information corresponds" may mean that the adhesion-related information matches or is similar. "Adhesion-related information is similar" may mean, when the adhesion-related information includes multiple information items, that the values ​​of a specific information item among the multiple information items match while the values ​​of at least one other information item do not match, or that the values ​​of any part of the multiple information items match while the values ​​of the other information items do not match. Alternatively, "adhesion-related information is similar" may mean that the values ​​of a certain information item in the adhesion-related information are similar, for example, the difference is 5% or less.

[0054] When the acquisition unit 122 acquires one or more ultraviolet irradiation intensity values, the setting unit 124 displays the one or more ultraviolet irradiation intensity values ​​as candidate values ​​for the ultraviolet irradiation intensity value for the current job on a predetermined display unit. The setting unit 124 also sets the ultraviolet irradiation intensity value selected by the user from the candidates as the ultraviolet irradiation intensity value for the current job, i.e., registers the value in the ultraviolet irradiation intensity storage unit 144. To this end, the setting unit 124 displays a selection screen on a predetermined display unit that includes the one or more ultraviolet irradiation intensity values ​​acquired by the acquisition unit 122 as candidate values ​​for the ultraviolet irradiation intensity value for the current job. The user selects an ultraviolet irradiation intensity value from one or more candidates on the selection screen. The setting unit 124 accepts the user's selection of the ultraviolet irradiation intensity value and sets the selected ultraviolet irradiation intensity value as the ultraviolet irradiation intensity value for the current job.

[0055] The value of the ultraviolet irradiation intensity may be changed from a value selected from candidates. For example, the value of the ultraviolet irradiation intensity may be fine-tuned from a value selected from candidates. Note that the ultraviolet irradiation intensity may be manually input instead of being selected from candidates. However, by using the ultraviolet irradiation intensity value obtained from performance information of past jobs, the ultraviolet irradiation intensity value for the current job can be easily determined.

[0056] When the job execution unit 126 receives a job execution start instruction from the user, it controls each device to execute the job of decorating the sheet. At this time, the ultraviolet irradiating units 48 and 66 irradiate ultraviolet light at the ultraviolet irradiation intensity stored in the ultraviolet irradiation intensity storage unit 144.

[0057] When a job is executed, the registration unit 128 registers information about the job, specifically the values ​​of each information item in FIG. 4, in the job performance information storage unit 142 at a predetermined timing. That is, the registration unit 128 registers the adhesiveness-related information, the ultraviolet irradiation intensity value, the number of processed sheets, and the execution date of the job in the job performance information storage unit 142. The predetermined timing may be, for example, when the job execution unit 126 receives an instruction to start execution of the job from the user, or when execution of the job is completed.

[0058] The transmission unit 130 transmits the job performance information stored in the job performance information storage unit 142 to an external server 200. The transmission unit 130 may transmit the job performance information at a predetermined interval or when the job execution is completed, but this is not limited to this. In either case, the server 200 collects job performance information from multiple sheet decoration systems 10. Therefore, by analyzing this performance information, the manufacturer of the sheet decoration system 10 can determine and propose appropriate ultraviolet irradiation intensities according to various adhesiveness-related information. Note that the information stored in the job performance information storage unit 142 may be collected by the server 200 via a recording medium, a mobile terminal device, or the like, by a service technician or other means.

[0059] In this way, when collecting and analyzing job performance information from multiple sheet decoration systems 10, it is necessary to minimize the influence of differences between individual sheet decoration systems 10 in the control items of each sheet decoration system 10. Therefore, each sheet decoration system 10 may store a correction value for each control item that compensates for differences between the individual sheet decoration systems 10, correct the value of the control item with this correction value, and execute the job based on this corrected value. On the other hand, the job performance information sent to the server 200 may be the value before correction with this correction value. In this way, the server 200 can collect and analyze job performance information without being influenced by differences between multiple individual sheet decoration systems, while the actual job can be executed using values ​​optimal for the individual sheet decoration system 10 that executes the job.

[0060] The correction value may be set based on actual measurements of each individual sheet decoration system 10. For example, when the sheet decoration system 10 is shipped from the factory, the actual UV irradiation intensity when a predetermined drive current is applied may be measured, and the amount of change in the drive current when the light is adjusted to the target irradiation intensity may be used as the correction value. In this case, it is desirable to measure all sheet decoration systems 10 at the time of shipment from the factory using the same type of properly calibrated measuring device. Alternatively, a sensor capable of measuring the actual irradiation intensity may be provided, and the measurement results of this sensor may be input to the control device 20. The control device 20 may then obtain the correction value by adjusting the light so that the actual irradiation intensity of the UV irradiation unit reaches the target irradiation intensity based on the input sensor measurement results.

[0061] FIG. 5 is a diagram showing an example of a settings screen 300. The settings screen 300 includes an adhesiveness-related information area 310 and a performance information area 320. The adhesiveness-related information area 310 includes a foil information area 312, a varnish information area 314, and a sheet information area 316. In the foil information area 312, information about the foil to be used in the current job is entered. In this example, a list of pre-registered foils is displayed in the foil information area 312, and the foil to be used in the current job can be selected from that list. In the varnish information area 314, information about the varnish to be used in the current job is entered. In this example, a list of pre-registered varnishes is displayed in the varnish information area 314, and the varnish to be used in the current job can be selected from that list. In the sheet information area 316, the presence or absence of lamination of the sheet to be used in the current job is entered. In this example, the checkbox is checked if lamination is required, and unchecked if lamination is not required. The acquisition unit 122 accepts the information input into each information item in the adhesiveness-related information area 310 as adhesiveness-related information for the current job.

[0062] The performance information area 320 displays performance information of past jobs that have adhesiveness-related information corresponding to the adhesiveness-related information of the current job that has been input into the adhesiveness-related information area 310. In more detail, the acquisition unit 122 acquires, from the job performance information storage unit 142, performance information of past jobs that have adhesiveness-related information corresponding to the adhesiveness-related information of the current job that has been input into the adhesiveness-related information area 310, and displays the information in the performance information area 320.

[0063] In this example, the acquisition unit 122 acquires the number of sheets processed and the date of implementation in addition to the ultraviolet irradiation intensity, and displays these in the performance information area 320. If the number of sheets processed is large or the implementation date is recent, the ultraviolet irradiation intensity is likely to be appropriate. Therefore, by displaying the number of sheets processed and the implementation date, it is easy to select an appropriate ultraviolet irradiation intensity.

[0064] In this example, the performance information area 320 displays performance information for past jobs in descending order of the number of processed sheets. In order to select an appropriate UV irradiation intensity, it is considered advantageous to display the number of processed sheets, which indicates the actual processing results. Therefore, by displaying the jobs in descending order of the number of processed sheets, it becomes easier to select an appropriate UV irradiation intensity. Furthermore, if the processing environment changes significantly depending on the season, or if it is considered advantageous to display jobs with more recent execution dates, the user may be able to display jobs with the most recent execution dates at the top, as needed.

[0065] Next, the effects of this embodiment will be described. According to this embodiment, the ultraviolet irradiation intensity of a past job corresponding to the adhesiveness-related information is presented as a candidate for the ultraviolet irradiation intensity of the current job. The user may use the presented candidate for ultraviolet irradiation intensity as is, or may fine-tune the presented candidate for ultraviolet irradiation intensity. In either case, the presentation of the candidate for ultraviolet irradiation intensity reduces the burden on the user of making the adjustments.

[0066] The present disclosure has been described above based on the embodiments. These embodiments are merely examples, and it will be understood by those skilled in the art that various modifications are possible in the combination of the respective components and processing steps, and that such modifications are also within the scope of the present disclosure. These modifications will be described below.

[0067] (Variation 1) The cumulative amount of UV light irradiated onto the varnish can be controlled not only by UV irradiation intensity but also by adjusting the values ​​of other control items of the sheet decoration system 10 that affect the cumulative amount of UV light irradiated onto the sheet varnish. Therefore, the technical concept of the embodiment can also be applied to proposing candidate values ​​for other control items in addition to or instead of UV irradiation intensity. In this case, the job performance information storage unit 142 stores the values ​​of the other control items in the past job as the job performance of the past job, the acquisition unit 122 acquires the values ​​of the other control items from the past job corresponding to the adhesiveness-related information, and the setting unit 124 presents them as candidate values ​​for the other control items in the current job.

[0068] Another control item may be the transport speed of the sheet passing through the irradiation range of the ultraviolet irradiation unit. The slower the sheet transport speed, the longer the time during which ultraviolet light is irradiated from the ultraviolet irradiation unit onto the varnish, and the greater the cumulative amount of ultraviolet light irradiated onto the varnish. The faster the sheet transport speed, the shorter the time during which ultraviolet light is irradiated from the ultraviolet irradiation unit onto the varnish, and the less the cumulative amount of ultraviolet light irradiated onto the varnish.

[0069] (Variation 2) Unlike the embodiment and the above-described modified examples, the external server 200 may include a job performance information storage unit. This job performance information storage unit may store performance information of past jobs collected from multiple sheet decoration systems 10. In this case, the acquisition unit 122 may acquire candidate values ​​for the control items from the job performance information storage unit of the server 200 via a network.

[0070] In this modification, the sending unit 130 transmits the job performance information to the server 200, including location information indicating the location of the sheet decoration system 10 that executed the job. The job performance information storage unit of the server 200 may store the job performance information along with this location information. The location information may also indicate the country or region where the sheet decoration system 10 is located. The type of sheet used to print the base image or the type of film used for lamination varies greatly depending on the country or region, but the same or similar types tend to be used within the same country or region. The same is true for the printing device used to print the base image, and the properties of the ink or toner used in the printing device. The type of sheet or film, the printing device, and the ink or toner used can affect the UV reflectance. Therefore, when retrieving candidate values ​​for the control items from the job performance information storage unit of the server 200, the acquiring unit 122 may select candidates with matching location information. In other words, the location information may be another information item in Modification 3, described below.

[0071] (Variation 3) In the embodiment and the above-described modified examples, the adhesiveness-related information includes the type of varnish, the type of foil, and whether or not lamination is performed, but is not limited to this.

[0072] The adhesiveness-related information may include only the type of varnish, only the type of foil, or only whether or not lamination is performed.

[0073] In addition, the adhesiveness-related information may include at least one other information item in addition to, or instead of, at least one of the type of varnish, type of foil, and whether or not lamination is performed.

[0074] Another information item may be, for example, the thickness of the varnish applied to the sheet. The thickness of the varnish applied to the sheet affects the ease with which the varnish hardens. When the varnish is relatively thick, the thicker the varnish, the greater the cumulative light intensity must be in order to ensure that the irradiated ultraviolet light reaches the entire varnish layer. On the other hand, due to oxygen inhibition, the greater the surface area of ​​the varnish exposed to air relative to its volume, the more difficult the varnish tends to harden due to oxygen inhibition. When the varnish is relatively thin, the effect of this oxygen inhibition is greater, so the thinner the varnish, the greater the cumulative light intensity must be.

[0075] Another information item may be, for example, the color of the area on the sheet where the varnish is applied (hereinafter also referred to as the base color). Not only the direct ultraviolet light emitted from the ultraviolet irradiation unit, but also the reflected ultraviolet light from the sheet contributes to the hardening of the varnish, and the higher the UV reflectance of the sheet, the more rapidly the varnish hardens. The UV reflectance of the sheet varies depending on its base color.

[0076] When varnish is applied to the printed area of ​​a sheet, the base color is the color of the ink or toner printed on the sheet. Generally, printing devices print using four colors of ink or toner: cyan, magenta, yellow, and black. These four colors of ink or toner vary at least depending on the printing device manufacturer, and may even vary between printing devices from the same manufacturer. Specifically, even inks or toners with the same color name may have different UV reflectances due to, for example, differences in pigments. In some cases, the appearance of the color may also be slightly different. Therefore, other information items may be a combination of the base color and the identification information of the printing device that printed that base color. The identification information of the printing device may include at least one of information for identifying the printing device manufacturer, information for identifying the model number, and information for identifying the product number.

[0077] When varnish is applied to unprinted areas of a sheet, the base color is the color of the sheet itself. Even sheets with the same color name may have different UV reflectances due to differences in pigments, for example, depending on the product number or manufacturer. In some cases, the color appearance may also be slightly different. Furthermore, even sheets with the same color name may have different product numbers or manufacturers, for example, depending on the minute irregularities on the sheet surface or the thickness of the coating applied to the sheet surface. This results in different penetration levels of the photoinitiator contained in the varnish, and thus different cumulative UV light doses required to semi-cure or fully cure the varnish. Therefore, other information items may include, for example, identification information for identifying the sheet. The sheet identification information may include at least one of information for identifying the sheet manufacturer, information for identifying the sheet model number, and information for identifying the sheet product number.

[0078] Other information items may include, for example, information indicating the surface condition of the sheet. Differences in the surface condition of the sheet can affect the UV reflectance of the sheet. The surface condition of the sheet may be matte or glossy, and the quality of the sheet, i.e., fine paper, coated paper, etc.

[0079] Another information item may be the type of lamination finish. Differences in the type of finish can affect the UV reflectance of the sheet. The type of finish may be matte or glossy, or it may be information to distinguish the manufacturer, brand, model number, or part number of the lamination film used in the processing.

[0080] Another information item may be the conveyance speed of the sheet passing through the irradiation range of the ultraviolet irradiation unit. The slower the sheet conveyance speed, the longer the time that ultraviolet light is irradiated onto the varnish from the ultraviolet irradiation unit, making it easier for the varnish to harden. As described in Variation 1, the sheet conveyance speed may also be a control item. In this case, the value of the sheet conveyance speed as a control item may be obtained based on information items other than the sheet conveyance speed, or the sheet conveyance speed as an information item may be used directly as the value of the sheet conveyance speed as a control item.

[0081] These other information items are all varnish-related information. Therefore, the adhesion-related information can also be considered as varnish-related information.

[0082] Fig. 6 is a diagram showing an example of the data structure of the job performance information storage unit 142 relating to Modification 3. Fig. 7 is a diagram showing an example of a setting screen 300 relating to Modification 3. In the examples of Figs. 6 and 7, the adhesiveness-related information includes the type of varnish, the type of foil, whether or not lamination is performed, as well as the thickness of the varnish and the base color.

[0083] In the adhesiveness-related information area 310 of the settings screen 300 shown in FIG. 7, the varnish information area 314 displays not only the varnish type but also the varnish thickness. A list of pre-registered varnish and thickness combinations is displayed in the varnish information area 314, and the user simply selects the varnish type and thickness combination to be used for the current job. Of course, the varnish type and thickness may also be selected individually. The sheet information area 316 allows the user to input the color of the area on the sheet to be varnished, i.e., the base color, in addition to whether or not lamination is required. The base color is entered by selecting and checking a checkbox corresponding to the base printing color of the area on the sheet to be varnished. In this example, the checkboxes for the base color are displayed in grayscale shades, and the user selects and checks the checkbox with a color close to the base color. However, this is not limited to this; checkboxes displayed in various colors may be displayed, and the user may select and check the checkbox with a color close to the base color.

[0084] 7 includes a search option area 330 in addition to the adhesiveness-related information area 310 and the performance information area 320. The search option area 330 is an area for specifying, for each information item, whether the performance information of a past job must "match" the adhesiveness-related information of the current job or whether "similarity" is also allowed as a condition for displaying the performance information of a past job in the performance information area 320. In this example, a check box is provided corresponding to each information item included in the adhesiveness-related information. Adhesion-related information corresponding to a checked check box requires "matching," while adhesion-related information corresponding to an unchecked check box is also allowed to "be similar."

[0085] At the start of setup, all check boxes in the search options area 330 may be checked. When all check boxes in the search options area 330 are checked, if there are no past jobs whose adhesiveness-related information matches the current job's adhesiveness-related information in all information items, nothing will be displayed in the performance information area 320. In this case, if an information item that allows "similar" is unchecked in the search options area 330, past jobs whose unchecked information items have adhesiveness-related information that is "similar" to the adhesiveness-related information of the current job will also be displayed in the performance information area 320. Therefore, even if there are no past jobs whose information items match the current job's, the user can gradually change the conditions to find appropriate past jobs. Furthermore, by selecting information items that allow "similar," past jobs that reflect the information items the user values ​​can be found.

[0086] The check boxes in the search options area 330 have a hierarchical structure. The upper level "Foil Information" corresponds to the lower level "Manufacturer," "Model Number," and "Color," the upper level "Sheet" corresponds to the lower level "Lamination Processing" and "Base Color," and the upper level "Varnish" corresponds to the lower level "Varnish Information" and "Varnish Thickness." Checking or unchecking a check box in a higher level is reflected in all corresponding information items in the lower levels. Checking a check box in a lower level is reflected only in the information item itself. This hierarchical structure allows multiple information items linked to each of "Foil," "Varnish," and "Sheet" to be specified together.

[0087] (Variation 4) Unlike the embodiment and the above-described modified examples, the control device 20 may include a control item value storage unit that stores the value of a control item for each piece of adhesiveness-related information. The value of this control item may be, for example, a value determined by a user of the sheet decoration system 10 based on experiments. Alternatively, the value of this control item may be, for example, a value determined based on job performance data of past jobs collected by the manufacturer of the sheet decoration system 10 or experiments. The acquisition unit 122 may acquire the value of the control item corresponding to the adhesiveness-related information of the current job from the control item value storage unit.

[0088] (Variation 5) In the embodiment and the above-described modified example, the values ​​of the control items acquired by the acquisition unit 122 are presented to the user as candidates for the values ​​of the control items of the current job. However, this is not limited to this, and the setting unit 124 may set the values ​​of the control items acquired by the acquisition unit 122 as the values ​​of the control items of the current job. In this case, the values ​​of the control items are automatically set based on the adhesiveness-related information of the current job. When the acquisition unit 122 acquires the values ​​of the control items of multiple past jobs, the value of the control item of the past job with the largest number of processed sheets may be adopted, or the value of the control item of the past job with the most recent registration date and time may be adopted. The value of the control item of the past job with the largest number of processed sheets may be adopted preferentially, and when there are multiple past jobs with the same number of processed sheets, the control item of the past job with the most recent registration date and time may be adopted preferentially.

[0089] (Variation 6) In the embodiment, the acquiring unit 122 acquires the adhesiveness-related information input by the user on the setting screen, but the invention is not limited to this. The acquiring unit 122 may acquire some or all of the information items included in the adhesiveness-related information according to reference information previously acquired by the control device 20, without relying on user input. The reference information may be, for example, image data representing a base image, and the acquiring unit 122 may acquire the base color from this image data. The data representing the base image may be input to a printing device in order to print the base image, or may be acquired by scanning a sheet on which the base image is printed. Furthermore, when a job involving data representing a base image is executed, the control device 20 may acquire the data representing the base image as performance information.

[0090] The reference information may be information acquired by sensors included in the sheet decoration system 10. For example, a transmission optical sensor is provided in the transport path of the web 52 so that its optical axis passes through the web 52, and the amount of light transmitted through the web 52 is acquired. Ultraviolet light from the transfer ultraviolet irradiation unit 66 passes through the web 52 and reaches the varnish. Therefore, the greater the amount of light transmitted through the web 52, the greater the accumulated amount of light, and the smaller the amount of light transmitted through the web 52, the smaller the accumulated amount of light. The control device 20 may acquire this accumulated amount of light as one piece of foil information. Furthermore, when a job is executed, the control device 20 may acquire the amount of light transmitted through the web 52 for that job as performance information.

[0091] (Variation 7) The technical concept of the embodiment is not limited to the case of transferring onto a sheet, that is, the object onto which the transfer device 16 transfers the transfer material may be something other than a sheet.

[0092] (Variation 8) In the embodiment, the tackiness of the semi-cured varnish is utilized to transfer the foil to the varnish on the sheet. In this modification, the foil has an adhesive function that is activated by heating, and this adhesive function is used to transfer the foil to the varnish. The following explains the differences from the embodiment.

[0093] 8 is a side view schematically showing a sheet decoration system 10 according to a modified example. FIG. 8 corresponds to FIG.

[0094] If the varnish applied to the sheet is prone to bleeding, the varnish application device 14 turns on the semi-curing ultraviolet irradiation unit 48 to semi-cure at least the surface of the varnish. Note that the varnish application device 14 does not necessarily have to be equipped with the semi-curing ultraviolet irradiation unit 48.

[0095] The foil held by the web 52 has an adhesive layer that exhibits adhesive strength when heated, i.e., the foil held by the web 52 exhibits adhesive strength when heated.

[0096] The transfer device 16 does not include a transfer ultraviolet irradiation unit. Instead, the transfer device 16 includes a pressure roller 53, an opposing member 56 that faces the pressure roller 53 below the pressure roller 53, and a heating unit (e.g., a heater) 54 for heating the foil. The pressure roller 53 presses the web 52 and the sheet against the opposing member 56. In the illustrated example, the opposing member 56 is a roller. Note that the opposing member 56 is not limited to a roller as long as it can sandwich the web 52 and the sheet between itself and the pressure roller 53. For example, the opposing member 56 may be a guide plate that forms part of the conveying surface.

[0097] At least one of the pressure roller 53 and the opposing member 56 is configured to be movable up and down. By moving at least one of the pressure roller 53 and the opposing member 56 up and down, the gap between the pressure roller 53 and the opposing member 56, in other words, the pressure with which the pressure roller 53 presses the web 52 and the sheet against the opposing member 56, can be adjusted.

[0098] The pressure roller 53 is heated by a heating unit (e.g., a heater) 54. That is, the pressure roller 53 heats the foil held by the web 52 and presses the foil against the sheet, thereby exerting the adhesive force of the foil, and the foil is adhered, i.e., transferred, to the varnish located higher than the upper surface of the sheet.

[0099] The heating unit 54 may be built into the pressure roller 53 as shown in the figure, or may be arranged external to the pressure roller 53. If the heating unit 54 is arranged external to the pressure roller 53, it is preferable that the heating unit 54 be arranged upstream of the pressure roller 53 to heat the web 52 and thus the foil so that the foil can exert sufficient adhesive strength during transfer. Note that the method of heating the foil is not limited to this. For example, a roller other than the pressure roller 53 may be heated by the heating unit 54, and that roller may heat the foil. Alternatively, for example, a hot air blower serving as the heating unit 54 may heat the foil.

[0100] The adhesive material contained in the adhesive layer of the foil may vary depending on the type of foil. Therefore, the amount of energy required to make the adhesive layer exhibit sufficient adhesive strength may vary depending on the type of foil. If the adhesive layer does not exhibit sufficient adhesive strength, poor adhesion may occur, in which the foil does not transfer to the sheet.

[0101] The amount of energy applied to the adhesive layer of the foil can be controlled by adjusting the heating temperature of the heating unit 54, which is a control item of the sheet decoration system 10. This adjustment is cumbersome and can be a burden to the user.

[0102] Therefore, in this modified example, the control device 20 stores the job results of past jobs and, based on the job results of the past jobs, suggests possible heating temperatures for the heating unit 54 for the current job that is about to be executed, thereby reducing the burden on the user.

[0103] The job performance information storage unit 142 of the control device 20 stores the adhesiveness-related information, the heating temperature by the heating unit 54, the number of processed sheets, and the execution date, ie, the registration date, in association with each other for the past jobs.

[0104] The adhesiveness-related information includes the type of foil, which may include, for example, the foil manufacturer, the foil model number, and the foil color.

[0105] The acquisition unit 122 refers to the job performance information storage unit 142 and acquires the value of the heating temperature by the heating unit 54 in the past job from the performance information of the past job that has adhesiveness-related information corresponding to the adhesiveness-related information of the current job.

[0106] When the acquisition unit 122 acquires one or more heating temperature values, the setting unit 124 displays the one or more heating temperature values ​​on a predetermined display unit as candidates for the heating temperature value in the current job. Furthermore, the setting unit 124 sets the heating temperature value selected by the user from the candidates as the heating temperature value by the heating unit 54 in the current job, i.e., registers it in the data storage unit 140.

[0107] The amount of energy applied to the adhesive layer of the foil is not limited to the heating temperature by the heating unit 54, and can also be controlled by adjusting the values ​​of other control items of the transfer device 16. Therefore, the job performance information storage unit 142 stores the values ​​of other control items in past jobs in addition to or instead of the heating temperature by the heating unit 54, the acquisition unit 122 acquires the values ​​of the other control items from the past job corresponding to the adhesiveness-related information, and the setting unit 124 presents them as candidates for the values ​​of the other control items in the current job.

[0108] Another control item may be the transport speed (feed rate) of the web 52. The slower the transport speed of the web 52, the longer the foil is heated and the more energy is applied to the foil. The faster the transport speed of the web 52, the shorter the foil is heated and the less energy is applied to the foil.

[0109] Incidentally, if the gap between the pressure roller 53 and the opposing member 56, or in other words, the pressure with which the pressure roller 53 presses the web 52 and the sheet against the opposing member 56, is not appropriate, poor adhesion, in which the foil is not transferred to the sheet, may occur. Adjusting this gap is complicated and can be a burden to the user. Therefore, another control item may be the gap between the pressure roller 53 and the opposing member 56, or the pressure with which the pressure roller 53 presses the web 52 and the sheet against the opposing member 56.

[0110] According to this modification, candidate values ​​for the control items are presented, thereby reducing the burden on the user in adjusting the values.

[0111] (Variation 9) The foil-holding web 52 is typically formed by vapor-depositing, coating, or attaching a metal or coloring material to a base film to create a transfer layer, which serves as the "foil" that serves as the transfer material. A release layer, adhesive layer, or other layer may be added to the transfer layer to enhance adhesion and ease of release from the base film during transfer. The long substrate sheet that supports the transfer material is not limited to a film; it may be a strip of woven fabric or other material that can hold the transfer material and transfer it to the object to be transferred in the transfer zone. Meanwhile, the transfer material held by the web 52 is not limited to a "foil"; it may be a thin layer other than metal. It may also be an ink ribbon, where the transfer material is applied to a base web, such as ink. The long substrate sheet that supports the transfer material is not limited to a film; it may be a strip of woven fabric or other material that can hold the transfer material and transfer it to the object to be transferred in the transfer zone.

[0112] (Variation 10) In the embodiment and the above-described modified examples, the control device 20 may include a machine learning program that learns the combination of the adhesiveness-related information acquired by the acquisition unit 122 for the current job and the UV irradiation intensity actually used in the execution of the current job, and may display candidates by referencing past processes learned through this program. The machine learning program may learn the entire process from the acquisition of adhesiveness-related information by the acquisition unit 122, display of candidate UV irradiation intensities for past jobs, user selection from the candidates, registration of the selected UV irradiation intensity, and execution of the current job using the registered UV irradiation intensity to generate its performance information. If the UV irradiation intensity is modified after registration, it is preferable to learn the modification as well. By learning and referencing many past jobs, it is possible to more appropriately select a UV irradiation intensity suitable for the input adhesiveness-related information. Furthermore, the learning and referencing of past processes described above may be performed using a neural network such as deep learning.

[0113] When the server 200 collects and analyzes job performance information from multiple sheet decoration systems 10, the server 200 may have a machine learning program that learns the combinations of adhesiveness-related information and UV irradiation intensity for collected past jobs, or the above-mentioned series of processes. By learning job performance information collected from multiple sheet decoration systems 10, the number n of job performance information increases, making it possible to set a more appropriate UV irradiation intensity.

[0114] Any combination of the above-described embodiments and modifications is also useful as an embodiment of the present disclosure. A new embodiment resulting from the combination has the combined effects of the combined embodiments and modifications.
