Description

Technical Field

[0001] This specification generally relates to inkjet printing, and particularly to the conveyance of a primer onto a printing substrate.

Background Art

[0002] The field of inkjet printing has made significant progress over the years, particularly in applying various types of inks onto different printing substrates. One of the printing substrates in the inkjet printing industry is cardboard, which has specific issues regarding ink adhesion and print quality. Conventionally, ultraviolet (UV) inks have been used for printing on cardboard, but the popularity of water-based inks as a more environmentally friendly solution has been increasing.

[0003] Water-based inks require a primer to ensure proper adhesion to the cardboard surface. The primer creates a surface suitable for the ink to bond to, preventing problems such as ink spreading and degradation of print quality. Currently, primer application in the industry is mainly performed using analog machines that press cardboard using rollers and apply the primer onto the surface of the printing substrate. This method is effective but relies on old technology, requiring additional processes and equipment in the printing process. The need for separate primer application equipment increases the complexity of the operation, energy consumption, and waste of materials.

[0004] Digital primer systems have been developed for some industrial printing applications, but specific problems still exist when using water-based inks on cardboard and other paper-based materials.

[Figure 2] A side view of a printing system including a print head and a heat source according to one or more embodiments is shown. [Figure 3] The image shows a side view of a printing system according to one or more embodiments. [Figure 4] This is a flowchart illustrating a method for laminating a primer and ink according to one or more embodiments. [Figure 5] This is a block diagram showing a computer system according to one or more embodiments. [Modes for carrying out the invention]

[0006] Methods, systems, and apparatus for aqueous inkjet printing using multilayer primers are disclosed. For example, the techniques disclosed herein provide an aqueous inkjet printing system configured to deposit and / or coat alternating layers of an inkjet primer and an aqueous inkjet ink onto a substrate. The system includes an inkjet printing apparatus comprising one or more primer print heads, one or more aqueous ink print heads, and a substrate. The system further includes a processor and a non-temporary computer-readable storage medium (e.g., computer memory) configured to cause the printing apparatus to deposit a first layer of primer onto the substrate, coat a first layer of aqueous ink on the first layer of primer, deposit a second layer of primer on the first layer of aqueous ink, and coat a second layer of aqueous ink on the second layer of primer. In some embodiments, after the system has completed depositing and / or coating the primer and aqueous ink layers, all of the primer and aqueous ink layers are dried simultaneously.

[0007] The advantages and benefits of the technology disclosed herein include the ability to achieve higher print quality because the primer layer improves ink adhesion and prevents ink spreading, resulting in sharper and more vivid images. For example, by laminating a primer between ink layers, the surface area of ​​the primer to which the ink can react is increased, improving print quality. Furthermore, since all layers can be dried simultaneously, the printing process can be streamlined and the overall time required for printing can be reduced. In addition, in analog printing processes, each layer of primer and ink must be dried before applying the next layer. This process requires the use of drying equipment that consumes a large amount of electricity, resulting in increased CO2 emissions from power plants. In contrast, the technology disclosed herein enables a continuous printing process without the need for intermediate drying. This not only simplifies the workflow but also significantly reduces the energy consumption associated with drying equipment.

[0008] These aspects, features, and embodiments can be expressed as methods, apparatus, systems, components, program products, means or steps for performing functions, and in other ways. These aspects, features, and embodiments will become apparent from the following description, including the claims.

[0009] The following description includes numerous specific details to facilitate understanding of this embodiment. However, it will be clear that this embodiment can be implemented without these specific details.

[0010] Figure 1 shows a perspective view of a printing system 100 according to one or more embodiments. This printing system 100 includes a print head 106, at least one heat source 112, and a substrate transport system 102. Embodiments may include various combinations of these components with other components (e.g., a dryer). For example, the heat source 112 may be present in some embodiments but not in others. In another example, a dryer or fixing unit may be included if the image 110 is not quickly transferred to the substrate. The substrate transport system 102 may include belts, actuators, pulleys, etc., for moving the substrate. The printing system 100 in Figure 1 may include a transfer belt 102, but other means for transporting and / or holding the substrate or transfer material 104, such as a rotating platform or a fixed bed, may also be used.

[0011] The print head 106 is configured to deposit ink and / or primer (e.g., an acrylic primer compound) onto the substrate or transfer material 104 in the form of an image 110. The substrate or transfer material 104, also called a former material, is flexible, so that the image 110 can be transferred to a substrate of complex shape. For example, the substrate or transfer material 104 may be a rubber former, a thermoformable material, etc. In some embodiments, the substrate or transfer material 104 is corrugated cardboard or other paper-based material. In some embodiments, the print head 106 is an inkjet print head that sprays ink and / or primer onto the substrate or transfer material 104 using, for example, a piezoelectric nozzle. In some embodiments, the ink is an aqueous energy-curable ink or a solvent-based energy-curable ink. The ink can be deposited in various forms, such as ink droplets and colored polyester ribbons.

[0012] In some embodiments, one or more heat sources 112 emit hot air or bring the substrate or transfer material 104 into contact with a heated surface to cure some or all of the ink deposited and / or applied on the substrate or transfer material 104. The heat sources 112 may be, for example, a hot air blower, a convection dryer, and / or an infrared (IR) lamp. Various combinations of these and other heat sources may be used.

[0013] The print head 106 and heat source 112 are shown directly adjacent to each other, i.e., adjacent without the interposition of any components. However, additional components may be present to assist in printing, curing, etc. For example, multiple different heat sources 112 may be positioned behind the print head 106. Figure 1 shows an example of arranging components to print an image 110 onto a substrate or transfer material 104. Other embodiments are conceivable in which components are added before, between, or after the illustrated components.

[0014] In some embodiments, one or more of the aforementioned components are housed within one or more carriages. For example, the print head 106 may be housed within a print carriage 108, and the heat source 112 may be housed within a curing carriage / frame / body 114. In addition to protecting the components from damage, the carriage / frame / body 114 may offer other advantages. For example, the curing carriage / frame / body 114 can limit the portion of the substrate or transfer material 104 and the image 110 that should be exposed during the curing process. The printing system 100 may include any combination of mechanical or electrical technology that enables pulleys, motors, rails, and / or carriages / frames / body to move along a substrate transport system (e.g., a transfer belt 102), i.e., relative to the substrate or transfer material 104. The transfer belt 102 is attached to a vacuum table 120 and moves over a vacuum platen 122 located on the vacuum table 120. In alternative embodiments, the carriage can be fixedly mounted to a rail or base of the printing system 100. In these embodiments, the substrate or transfer material 104 can be moved relative to the print head 106, heat source 112, etc., so that ink and primer can be deposited onto the substrate or transfer material 104.

[0015] In various embodiments, some or all of the components are controlled by a computer system 116. The computer system 116 is identical or similar to the computer system 500, which is illustrated and described in more detail with reference to Figure 5. The computer system 116 allows the user to input print instructions and information, change print settings (e.g., by changing curing settings), modify the print process, and so on.

[0016] Figure 2 shows a side view of a printing system 200 including a print head 202 and a heat source 204 according to one or more embodiments. Although a single-pass configuration is shown in Figure 2, a multi-pass, i.e., scan configuration may be employed in other embodiments. In some embodiments, a first layer of primer and ink is deposited in a first pass, a second layer of primer and ink is deposited in a second pass, and so on. Similarly, embodiments can be modified to suit various printers (e.g., flatbed printers, drum printers, or lane printers). For example, a flatbed printer may include a stable bed and a traverse print head, a stable print head and a traverse bed, etc. The workpiece transport system is mounted on a vacuum table 120 and moves on a vacuum platen 122 located on the vacuum table 120.

[0017] The print head 202 may include different primers and / or inks / color drums (e.g., cyan, magenta, yellow, and black (CMYK)) corresponding to colored polyester ribbons deposited on the surface of the substrate and / or transfer material 206. In some embodiments, one or more print heads 202 are configured to deposit and / or coat primers onto the substrate 206, and one or more print heads 202 are configured to deposit and / or coat inks onto the substrate 206. Path A represents the medium feeding direction, i.e., the direction in which the substrate or transfer material 206 moves during the printing process. Path D represents the distance between the print head 202 and the surface of the substrate or transfer material 206. In some embodiments, a heat source 204 cures some or all of the primers and / or inks 208 applied on the substrate or transfer material 206 by one or more print heads 202.

[0018] The heat source 204 may be, for example, a hot air source, a convection source, and / or an infrared lamp. In some embodiments, different heat sources may be used in combination. Generally, the heat source 204 is selected so that the curing temperature does not exceed the temperature at which the ink 208 begins to sublimate.

[0019] Figure 3 shows a side view of the printing system 300 according to one or more embodiments. In some embodiments, the printing system 300 generally includes the same and / or similar features as the printing systems 100 and 200 described with reference to Figures 1 and 2, respectively.

[0020] The printing system 300 is an aqueous inkjet printing system configured to improve print quality and efficiency by applying multiple layers 310, 312 of primer and multiple layers 320, 322 of aqueous ink. For example, in this embodiment, a configuration is described in which two layers 310, 312 of primer and two layers 320, 322 of aqueous ink are alternately laminated. However, those skilled in the art will understand that it is also possible to alternately laminate other numbers of primer layers with other numbers of aqueous ink layers (e.g., three, five, six, twelve, or more layers of primer and aqueous ink). The printing system 300 comprises a substrate 302, one or more primer print heads 330 configured to deposit the primer layers 310, 312 on the substrate 302 and the aqueous ink layers 320, 322, and one or more ink print heads 340 configured to apply the aqueous ink layers 320, 322 on the primer layers 310, 312. In some embodiments, the system is controlled by a processor (e.g., processor 502 in Figure 5) and utilizes a non-temporary computer-readable storage medium (e.g., non-volatile memory 510 in Figure 5) that stores instructions for executing the printing process.

[0021] In some embodiments, a first layer 310 of primer is deposited on the substrate 302 by one or more primer print heads 330. Subsequently, a first layer 320 of aqueous ink is coated onto the first layer 310 of primer by one or more ink print heads 340. In some embodiments, the first layer 310 of primer and the first layer 320 of aqueous ink are deposited and / or coated as part of a first pass 350.

[0022] In some embodiments, a second layer 312 of primer is deposited on a first layer 320 of aqueous ink by one or more primer print heads 330. Subsequently, a second layer 322 of aqueous ink is coated on the second layer 312 of primer by one or more ink print heads 340. In some embodiments, the second layer 312 of primer and the second layer 322 of aqueous ink are coated as part of a second pass 360. This lamination helps ensure optimal reaction between the primer and ink, improving print quality.

[0023] In some embodiments, the printing system 300 further includes one or more dryers 370 configured to dry the primer layers 310, 312 and aqueous ink layers 320, 322 deposited on the substrate 302. In some embodiments, the first layer of primer 310 and the first layer of aqueous ink 320 are dried before applying the next layer (e.g., the first pass 350 is dried before the next pass), and the second layer of primer 312 and aqueous ink 322 is dried after the first layer has dried. That is, each pass (e.g., the first pass 350, the second pass 360, etc.) is dried after printing. In some embodiments, the first and second layers of primer 310, 312 are dried simultaneously with the first layer 320 and the second layer 322 of aqueous ink by one or more dryers 370, thus streamlining the process, reducing the overall drying time, and saving energy consumption due to the operation of the dryers 370. In some embodiments, each layer is dried before the next layer is applied. For example, a first layer 310 of primer is deposited on the substrate 302, the first layer 310 of primer is dried, a first layer 320 of aqueous ink is applied on top of the first layer 310 of primer, the first layer 320 of aqueous ink is dried, and so on. Those skilled in the art will understand that additional combinations of primer deposition, aqueous ink application, and drying are possible (e.g., a first pass 350 is deposited / applied and dried, then a second layer 312 of primer is added and dried, and then a second layer 322 of aqueous ink is applied). It will also be understood that the order of primer deposition, aqueous ink application, and drying can be changed based on the number of primer and aqueous ink layers used.

[0024] In some embodiments, the printing system 300 is configured to deposit one or more layers of the primer layers 310, 312 and / or the aqueous ink layers 320, 322 based on one or more parameter values associated with the primer layers 310, 312 and / or the aqueous ink layers 320, 322. The parameters and / or parameter values can include, for example, the color, intensity, detail, gradient, resolution, and amount of the primer and / or ink. This ensures control of the application of the primer and ink and enables customization / variability of the printing characteristics. For example, the first layer 320 of the aqueous ink can include a first parameter value related to the concentration, color, and amount of the ink, and the second layer 322 of the aqueous ink can include a second parameter value related to the concentration, color, and amount of the ink. As another example, the first layer 310 of the primer can include a first parameter value related to the amount of the primer, and the second layer of the primer 312 can include a second parameter value related to the amount of the primer.

[0025] In some embodiments, the printing system 300 determines a total parameter value associated with the first and second layers 310, 312 of the primer and / or the first and second layers 320, 322 of the aqueous ink, and assigns a first portion (e.g., 50% of the total parameter value) of the total parameter value to the first layer 310 of the primer and / or the first layer 320 of the aqueous ink, and the second portion (e.g., the remaining 50% of the total parameter value) to the second layer 312 of the primer and / or the second layer 322 of the aqueous ink. In some embodiments, the first and second quantity values are approximately the same value, and each value represents approximately 50% of the total quantity value associated with the first and second layers 310, 312 of the primer and / or the second layer 320, 322 of the aqueous ink. In other embodiments, the first quantity value is different from the second quantity value (e.g., the first layer 310 of the primer is 40% while the second layer 312 of the primer is 60%), enabling customized application based on specific printing requirements.

[0026] In some embodiments, the printable substrate 302 is composed of a substantially paper-based material and is suitable for a wide range of printing applications including packaging, labels, and other paper-based products. In some embodiments, the printable substrate 302 is cardboard.

In some embodiments, one or more steps of method 400 are performed by any of the printing systems 100, 200, and 300 described with reference to FIGS. 1-3. In some embodiments, one or more steps of method 400 are performed using the computer system 500 of FIG. 5.

[0028] In block 402, a printable substrate (e.g., cardboard, other paper-based material, etc.) is obtained. In some embodiments, the printable substrate is configured to be conveyed on an inkjet printing device similar to / identical to the system / device described with reference to FIGS. 1-3. For example, a conveyor belt can convey the printable substrate to one or more print heads that are part of a printing carriage.

[0029] In block 404, the expected number of ink layers and / or primer layers (e.g., two layers, each being a primer layer and an ink layer) is determined to correspond to the given printing needs. In block 406, one or more total parameter values associated with the expected number of primer layers and / or ink layers are determined. Examples of parameter values include amount, intensity, position relative to a coordinate plane, coloring, etc. <0000​​​​​​In block 410, a first layer of ink is applied (e.g., laminated) onto a first layer of primer. In some embodiments, the first layer of ink is applied based at least partially on one or more determined total parameter values. For example, the total amount of ink can be determined, and a first portion of that amount can be allocated to the first layer of ink applied onto the first layer of primer.

[0032] In block 412, a second layer of primer is deposited on the first layer of ink. In some embodiments, the second layer of primer is deposited based at least in part on one or more determined total parameter values. For example, a second portion of the total amount of primer can be allocated to the second layer of primer deposited on the first layer of ink.

[0033] In block 414, a second layer of ink is applied on top of a second layer of primer. In some embodiments, the second layer of ink is applied based at least in part on one or more determined total parameter values. For example, a second portion of the total amount of ink can be allocated to the second layer of ink applied on top of the second layer of primer. In some embodiments, method 400 includes applying primer layers and ink layers alternately (e.g., repeating blocks 412 and 414) as required for a given printing application.

[0034] In block 416, in some embodiments, all primer and ink layers are dried simultaneously (e.g., at the end of the printing process). In some embodiments, each alternating layer of primer and ink (e.g., a first pass including a first layer of primer and a first layer of ink) is dried before the next primer and ink layer is deposited / coated.
