DETAILED DESCRIPTION OF THE INVENTION

[0020] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram showing the configuration of a transfer system 1 according to an embodiment. FIG. 2 is a flowchart illustrating the basic steps of the transfer method according to the embodiment. FIG. 3 is a schematic diagram illustrating each step of the transfer method. (a) of FIG. 3 shows an example of an image IM printed on a medium M in the printing step. (b) of FIG. 3 shows an adhesive layer AL formed on the image IM in the laminating step and heating step. (c) of FIG. 3 is a diagram showing the state in which the medium M is superimposed on the workpiece Wk before the pressing step. (d) of FIG. 3 is a diagram showing the workpiece Wk after the peeling step. In the drawings, the adhesive layer AL is shown with cross-hatching.

[0021] As shown in FIG. 1, the transfer system 1 has a printer 2 (printing device), a shaker 4 (adhesive application device), and a heat press 8 (press device). The X, Y, and Z directions shown in FIG. 1 are intended to illustrate an example of the positional relationship between the printer 2 and the shaker 4. The Z direction is along the vertical line (direction of gravity) and is the up-down direction on the paper surface of FIG. 1. The X and Y directions are along the horizontal direction and are perpendicular to the Z direction. Note that the thickness of the medium M is exaggerated in the oven 6 and heat press 8 in FIG. 1.

[0022] The transfer system 1 can produce a printed matter by transferring an image IM (see FIG. 3) to a workpiece Wk using, for example, a transfer method called DTF (Direct to Film). In DTF, the image IM is transferred to the workpiece Wk by placing a medium M on which the image IM is printed on the workpiece Wk and heat-pressing the medium M. The medium M may be, for example, a resin film with a release layer formed on its surface. Note that a medium M other than a film, such as paper, may also be used as long as it is treated so that the image IM can be released from the medium after transfer. The workpiece Wk can be made of various fiber fabrics such as cotton, polyester, nylon, leather, nonwoven fabric, wood, metal plate, or a combination of at least some of these. The workpiece Wk can also be, for example, clothing such as a T-shirt made from these materials, or cloth products such as tapestries and banners.

[0023] As shown in FIG. 2, the transfer method (printed material manufacturing method) executed in the transfer system 1 includes a printing process (step S01), a powder application process (step S02), a powder fixing process (step S03), a pressing process (step S04), and a peeling process (step S05). As shown in FIG. 1, in the printing process, an image IM is printed on a medium M by a printer 2 (see FIG. 3(a)). As shown in Figure 1, in the powder application process, a shaker 4 applies hot melt powder HP (adhesive) to an image IM printed on a medium M. As will be described in detail later, the hot melt powder HP contains a mixture of functional powder FP. As shown in Figure 1, in the powder fixing process, the medium M is heated by a shaker 4, and the hot melt powder HP applied to the image IM is melted and fixed to the image IM, thereby forming an adhesive layer AL (see Figure 3(b)) on the surface of the image IM. In the pressing step, the printed surface of the image IM on the medium M is placed on the surface of the workpiece Wk (see (c) of FIG. 3), and the medium M and the workpiece Wk are pressed together using a heat press 8 (see FIG. 1). As a result, the image IM on which the adhesive layer AL is formed is adhered to the workpiece Wk. In the peeling process, the medium M is peeled off from the workpiece Wk. This completes the printed matter with the image IM transferred to the workpiece Wk, as shown in (d) of Figure 3. Note that, as shown in (a) and (d) of Figure 3, the image IM transferred to the workpiece Wk is a reversed version of the image IM printed by the printer 2.

[0024] The printer 2 can be, for example, an inkjet printer that performs printing by ejecting droplets of ink from nozzles 23. Figure 1 shows, as an example, the printer 2 that performs printing while unwinding and transporting a rolled medium M in the X direction. The printer 2 includes a platen 21 that supports the medium M, and a head 22 that is disposed opposite the platen 21 in the Z direction and that ejects ink onto the medium M supported by the platen 21. The head 22 is provided with a gap between it and the upper surface of the platen 21. A plurality of nozzles 23, which are ink ejection ports, are provided on the lower surface of the head 22 that faces the platen 21. The head 22 is movable in the Y direction by a movement mechanism (not shown).

[0025] A shaft 24 that can rotate about an axis Y1 that runs along the Y direction is provided on the X1 side of the platen 21. Media M is wound in a roll and supported on the outer periphery of the shaft 24. When the media M is fed to the X2 side by a feed mechanism (not shown), the shaft 24 rotates clockwise about the axis Y1 to unwind the media M. The medium M is wrapped around the upper surface of the platen 21 in a direction crossing the X direction. Ink is ejected from the nozzles 23 of the head 22 onto the medium M positioned on the upper surface of the platen 21.

[0026] Although detailed illustration is omitted, the head 22 of the printer 2 has nozzle rows in which a plurality of nozzles 23 are arranged, and each nozzle row can be set to eject a different type of ink. The ink used in the printer 2 is not limited to a particular type, but DTF can use water-based ink. The ink may be, for example, an ink containing a pigment, which is a coloring material. The ink containing a pigment may be, for example, a process color ink of C (cyan), M (magenta), Y (yellow), or K (black) (hereinafter referred to as "color ink"), or a white ink. Alternatively, the ink may be a clear ink that does not contain a coloring material such as a pigment.

[0027] Although not shown in the figure, the printer 2 is equipped with a controller that controls the operation of each component. Print data created based on data of an image to be printed on the medium M is input to the controller. The controller controls the type of ink to be ejected onto the medium M, as well as the ejection position and ejection amount of each ink, in accordance with the print data, thereby printing an image on the medium M.

[0028] As shown in FIG. 1, the printer 2 can be provided with a sensor 25 capable of sensing the medium M. The sensor 25 can be, for example, an optical sensor including a light-emitting unit and a light-receiving unit that receives light emitted from the light-emitting unit and reflected by the medium M. Alternatively, the sensor 25 can be a camera that can photograph the medium M. The controller of the printer 2 can adjust the operation of each unit of the printer 2 based on the detection results of the sensor 25.

[0029] After the printing process is completed, the medium M is sent out from the platen 21 by a sending mechanism (not shown) and carried into the shaker 4 located on the X2 side of the printer 2. 1 shows the printer 2 compatible with roll-shaped media M, but the printer 2 may also be configured to print on, for example, sheet-shaped or board-shaped media M. In this case, the printer 2 may include a flat table platen 21 and a movement mechanism that moves the head 22 relative to the platen 21 in the X and Y directions.

[0030] As shown in FIG. 1, the shaker 4 includes an application section 41 that applies hot melt powder HP to the medium M, a heating section 44 that heats the medium M to which the hot melt powder HP has been applied, and a winding section 47 that winds up the dried medium M into a roll. The application unit 41, the heating unit 44, and the winding unit 47 are arranged in this order from the X1 side to the X2 side in the X direction. The winding unit 47 includes a shaft 48 arranged along the Y direction and a motor (not shown) that rotates the shaft 48 about an axis Y2 that extends along the Y direction. The media M is wound in a roll around the outer periphery of the shaft 48 and supported thereon. When the motor is driven, the shaft 48 rotates clockwise about the axis Y2, and the media M carried in from the printer 2 is transported to the X2 side in the X direction, passes through the application unit 41 and the heating unit 44, and is wound around the outer periphery of the shaft 48.

[0031] 1, a support unit 45 that supports the media M is provided on the shaker 4 below the heating unit 44 in the Z direction. A recess Mb for the media M is formed on the shaker 4 below the application unit 41 in the Z direction. The media M that has been loaded into the shaker 4 hangs down in the Z direction due to its own weight between the platen 21 of the printer 2 and the support unit 45 provided below the heating unit 44 in the Z direction, forming the recess Mb. The recess Mb is formed in a position that overlaps with the application unit 41 when viewed from the Z direction.

[0032] The application unit 41 can be configured, for example, from a nozzle that sprays hot melt powder HP. The application unit 41 supplies the hot melt powder HP to the recessed portion Mb of the medium M located below. As a result, the hot melt powder HP supplied from the application unit 41 accumulates in the recessed portion Mb. As the medium M passes through the recessed portion Mb, it comes into contact with the hot melt powder HP accumulated in the recessed portion Mb. The hot melt powder HP comes into contact with the image printed on the medium M. Because the medium M is transported directly from the printer 2 to the shaker, the ink in the image printed on the medium is not yet dry. Therefore, the hot melt powder HP adheres to the wet image (powder application process).

[0033] A vibration mechanism 45a is built into the support unit 45 provided on the X2 side of the application unit 41. Because the media M is supported by the support unit 45, the vibration of the vibration mechanism 45a is transmitted via the support unit 45 to the entire media M being transported through the shaker 4. Vibration of the media M causes the hot melt powder HP to move over the media, making it easier to adhere to the image. Vibration of the media also allows excess hot melt powder HP not adhering to the image to fall off the media M.

[0034] Known hot melt powder HPs for DTF can be used. Suitable hot melt powder HPs include, for example, resin powders containing urethane, acrylic, polyester, polyamide, or mixtures thereof. Furthermore, hot melt powder HPs may contain, for example, a thermoplastic polymer as the main component and contain no water or organic solvents. Hot melt powder HPs that are solid at room temperature and melt and become sticky when heated can be used.

[0035] As shown in Figure 1, functional powder FP can be mixed with hot melt powder HP. Functional powder FP is a powder that has an optical or visual effect, and when used in printed matter, can impart functions such as luminescence and decoration. Functional powder FP can contain, for example, phosphorescent pigments (luminous powders) and effect pigments. A phosphorescent pigment is a pigment containing a substance (such as strontium aluminate) that stores light and emits light in the dark. Effect pigments can be pigments with decorative functions, such as glitter pigments, glitter pigments, and pearl pigments. Effect pigments can include, for example, flakes of aluminum, alumina, silica, glass, etc. Effect pigments can include, for example, powders of crushed minerals such as mica and tourmaline, shells, fish scales, etc., as well as powders of bismuth oxychloride, borosilicate coated with titanium oxide, bismuth oxychloride, stainless steel, etc.

[0036] As described above, there are various types of functional powder FP. Any one of these functional powder FPs may be mixed with the hot melt powder HP, or a combination of several types may be mixed. The mixing ratio of the functional powder FP and the hot melt powder HP can be determined appropriately, taking into consideration the balance between the functionality required of the functional powder FP and the adhesiveness required of the hot melt powder HP. Instead of providing the application unit 41 such as a spray nozzle, the user may manually supply the hot melt powder HP to the recesses Mb of the medium M.

[0037] As shown in FIG. 1, the heating unit 44 includes a heater 46 that heats the medium M. The heater 46 heats the medium M to dry any ink in the image that has not yet dried, and melts the hot melt powder HP that has adhered to the image, thereby fixing it to the image (powder fixing process). Furthermore, the hot melt powder HP becomes sticky when melted. As a result, an adhesive layer AL that can be attached to the workpiece Wk is formed on the surface of the image IM, as shown in FIG. 3(b).

[0038] 1 shows an example in which the shaker 4 is integrally provided with the heater 46, which is a mechanism for heating the media M, but a mechanism for heating the media M may be provided separately from the shaker 4. For example, when the media M is in a sheet shape rather than a roll shape, an oven or the like can be provided as a mechanism for heating the media M. The heating conditions for the medium M are not limited, but for example, a heating temperature of about 130° C. (for example, about 120 to 150° C.) may be maintained for about 5 minutes (for example, about 1 to 10 minutes).

[0039] The medium M that has passed through the heating section 44 is wound into a roll on the shaft 48 of the winding section 47. The user can remove the medium M from the shaft 48 by An area including the image IM to be transferred onto the workpiece Wk (see (b) of FIG. 3) is cut out and superimposed on the workpiece Wk. At this time, as shown in (c) of FIG. 3, the printed surface of the image IM of the medium M is superimposed facing the surface of the workpiece Wk. As a result, the adhesive layer AL formed on the surface of the image IM comes into contact with the surface of the workpiece Wk. The user presses the workpiece Wk, on which the media M are stacked, with a heat press 8.

[0040] 1, the heat press 8 includes a placement section 81 on which the workpiece Wk is placed, and a press section 82 that is disposed above the placement section 81 in the Z direction and sandwiches and presses the workpiece Wk between the placement section 81 and the press section 82. A heater 83 is built in the placement section 81. The user places the workpiece Wk, which has the media M superimposed thereon, on the placement section 81 and drives the heater 83 to heat the media M. The user then presses down on the press section 82, sandwiching and pressing the workpiece Wk between the press section 82 and the placement section 81. This causes the image IM, on which the adhesive layer AL has been formed, to be pressed against the surface of the workpiece Wk, and the image IM adheres to the workpiece Wk.

[0041] After the pressing process is completed, the user removes the workpiece Wk from the heat press 8 and peels the medium M from the workpiece Wk and the image IM adhered to the workpiece Wk. As shown in (d) of Figure 3, a printed matter is produced in which the image IM is transferred to the workpiece Wk.

[0042] In order to fix the image IM transferred to the workpiece Wk, a pressing process may be performed again after the peeling process. At this time, pressing may be performed with paper or the like sandwiched between the workpiece Wk placed on the placement section 81 of the heat press machine 8 and the pressing section 82. This makes it possible to reduce peeling of the image IM from the workpiece Wk during pressing.

[0043] As described above, in this embodiment, the functional powder FP is mixed into the hot melt powder HP to be attached to the image IM. Functional powder FP can be applied to printed materials to increase their added value. However, functional powder FP generally has a large particle size, making it difficult to eject from the nozzle of an inkjet printer. When using functional powder FP, it is possible to apply it to media M by hand, for example. However, this process takes time, and it can be difficult to express complex characters, figures, etc. by hand.

[0044] In this embodiment, the functional powder FP is mixed with the hot melt powder HP and is then applied to the image IM together with the hot melt powder HP in the powder application step (FIG. 2, step S02). In other words, the functional powder FP can be applied to the location where the image IM is printed by the printer 2, making it possible to handle complex characters, figures, etc. The adhesive layer AL formed by melting the hot melt powder HP is located underneath the ink layer that forms the image IM when it is transferred to the workpiece Wk. If the ink layer contains color ink, the functional powder FP with optical or visual effects contained in the adhesive layer AL is obscured by the color ink and becomes difficult to see. On the other hand, if the ink layer does not contain color ink and is composed of white ink or clear ink, the functional powder FP contained in the adhesive layer AL becomes more visible because light is scattered in the ink layer or passes through the ink layer. In this embodiment, a printing process is carried out to produce a printed product that utilizes the functional powder FP, taking into account the relationship between the functional powder FP and various inks. The printing process is not limited to a specific embodiment, but three examples of the printing process are described in detail below.

[0045] 4 is a diagram illustrating a first example of the printing process. In the drawings that explain the following examples of the printing process, the medium M and the workpiece Wk are shown schematically as rectangles. To make it easier to distinguish between the medium M and the workpiece Wk, the medium M is shown with a solid line and the workpiece Wk is shown with a two-dot chain line. Fig. 4(a) shows an example of an image IM formed on a medium M in a printing process. Fig. 4(b) shows a cross section of the image IM after a heating process, taken along line AA in Fig. 4(a). Fig. 4(c) shows a cross section of the image IM after it has been transferred to a workpiece Wk. In the cross-sectional view, the hatching of the cross sections of the media M, workpiece Wk, white ink WH, and clear ink CL has been omitted. The thickness of the layers formed by each ink and the adhesive layer AL has also been exaggerated. Furthermore, because the cross-sectional view is merely a schematic diagram, there are some areas where the dimensions do not match those of the original drawing. This also applies to the cross-sectional views shown subsequently.

[0046] In a first example of the printing process, printing is performed so that the functional powder FP is visible over the entire surface of the image IM. 4(a), in a first example of the printing process, an image IM is printed with white ink WH or clear ink CL on a medium M. An ink layer of the white ink WH or clear ink CL is formed on the medium M. In the powder application process, a hot melt powder HP mixed with functional powder FP is layered on the surface of the ink layer. In the powder fixing process, the hot melt powder HP melts, and an adhesive layer AL containing functional powder FP is formed on the surface of the ink layer, as shown in Figure 4(b). Through the pressing and peeling processes, the image IM with the adhesive layer AL formed thereon is transferred from the medium M to the workpiece Wk. As shown in Figure 4(c), the adhesive layer AL is the bottom layer of the workpiece Wk, and an ink layer of white ink WH or clear ink CL is layered on top of the adhesive layer AL. In this case, the functional powder FP contained in the adhesive layer AL becomes visible through the ink layer of white ink WH or clear ink CL. In this way, in the first example of the printing process, the functional powder FP becomes visible over the entire surface of the image IM printed in the printing process.

[0047] FIG. 5 is a diagram illustrating a second example of the printing process. Figure 5(a) shows an example of an image formed on the medium M during the printing process. Figure 5(b) shows a cross section of the image after the heating process, taken along line AA in Figure 4(a). Figure 5(c) shows the image after transfer to the workpiece Wk, and Figure 5(d) shows a cross section taken along line BB in Figure 5(c). In the second example, a phosphorescent pigment LP is used as the functional powder, and in the printing process, a masking portion MK that blocks the light emitted by the phosphorescent pigment LP is printed with color ink. FIG. 5 shows an example in which an image having an overall rectangular area IA is transferred onto a workpiece Wk. As shown in FIG. 5(a), in the second example of the printing process, first, the printer 2 prints white ink WH over the entire surface of the area IA (white printing process). Next, the printer 2 prints a masking portion MK in the area IA with color ink (color printing process). Specifically, as shown in FIG. 5(a), in the area IA1 on the right side of the area IA, the masking portion MK is printed in the background except for the letters "AB" in the center. In the area IA2 on the left side of the area IA, the masking portion MK is printed in the area of ​​the letters "CD" in the center. As shown in FIG. 5(b), an ink layer of white ink WH is formed on the medium M, and a masking portion MK made of color ink is layered on part of the ink layer of white ink WH.

[0048] In the printer 2, the white printing process and the color printing process may be carried out independently or in parallel. When the white printing process and the color printing process are performed independently, the medium M is fed to the X2 side on the platen 21 (see Figure 1) while printing white ink WH in the area IA, and then the medium M is pulled back to the X1 side, and while being fed to the X2 side again, the masking area MK is printed with color ink. When the white printing process and color printing process are performed in parallel, white ink WH is printed in area IA while the medium M is fed toward the X2 side on the platen 21. Furthermore, color inks are printed following the white ink WH in the areas within area IA where the masking portions MK are printed. In this case, there is no need to return the medium M to the X1 side, which improves printing speed. Similarly, in the examples described below, when a plurality of printing processes are performed consecutively, these printing processes may be performed independently or in parallel.

[0049] Next, an adhesive layer AL containing the phosphorescent pigment LP is formed over the entire surface of region IA of the image through the powder application process and powder fixing process. The image is transferred from the media M to the workpiece Wk through the pressing process and peeling process. As shown in Figures 5(c) and 5(d), the adhesive layer AL containing the phosphorescent pigment LP becomes the bottom layer of the workpiece Wk after transfer. The letters "AB" in region IA1 of the image and the background of region IA2 have only a layer of white ink WH laminated on the adhesive layer AL. Therefore, in these areas, the luminescence of the phosphorescent pigment LP contained in the bottom adhesive layer AL is transmitted through the white ink WH layer and becomes visible. Meanwhile, the background of region IA1 of the image and the letters "BC" in region IA2 have a masking portion MK and a layer of white ink WH laminated on top of the adhesive layer AL. Therefore, in these areas, the luminescence of the phosphorescent pigment LP is blocked by the masking portion MK, making it difficult to see. In this second example of the printing process, by printing a masking portion MK that blocks the light emitted by the luminous pigment LP contained in the adhesive layer AL, it is possible to add luminous functionality to desired locations on the image, making it possible to express complex characters and figures using the luminous pigment LP.

[0050] FIG. 5(e) is a diagram showing a variation of the second example of the printing process. As described above, in the color printing process, the masking portion MK is printed with color ink, but the portions of the image area IA other than the masking portion MK may be printed with white ink WH or clear ink CL. In this case, as shown in Figure 5(e), in the portions of the image transferred to the workpiece Wk where the masking portion MK is not printed, a layer of white ink WH or clear ink CL is formed between the adhesive layer AL and the layer of white ink WH. In this case, the luminescence of the luminescent pigment LP contained in the adhesive layer AL is transmitted through the layer of clear ink CL or white ink WH, making the luminescence of the luminescent pigment LP visible. In this variation, the thickness of the image after transfer is uniform across the entire surface of the image, and is therefore suitable, for example, when a smooth surface is required for the printed material.

[0051] FIG. 6 is a diagram showing a third example of the printing process. Fig. 6(a) shows an example of an image IM formed on a medium M in a printing process. Fig. 6(b) shows a cross section of the image IM after a heating process, taken along line AA in Fig. 6(a). FIG. 6(c) shows the image IM after transfer onto the workpiece Wk, and FIG. 6(d) shows a cross section taken along line BB in FIG. 6(c). FIG. 6 shows an example in which a phosphorescent pigment LP is used as the functional powder. The third example of the printing process is suitable for forming pinpoint light-emitting portions in an image IM printed with color ink, for example.

[0052] As shown in Figures 6(a) and 6(b), in a third example of the printing process, an image IM is printed on a medium M using color inks CMYK by a printer 2 (color printing process). At this time, areas IMa and IMb in the image IM are printed using clear ink CL. Next, the printer 2 prints white ink WH over the entire image IM (white printing process).

[0053] As shown in Figure 6(b), an adhesive layer AL containing the phosphorescent pigment LP is formed on the surface of the image IM through the powder application process, powder fixing process, and heating process. In the areas of the image IM other than areas IMa and IMb, the adhesive layer AL is laminated on the layer of color inks CMYK and white ink WH. In the areas IMa and IMb of the image, the adhesive layer AL is laminated on the ink layer of clear ink CL and white ink WH.

[0054] The image IM is transferred from the medium M to the workpiece Wk through the pressing step and peeling step. As shown in Figures 6(c) and 6(d), the adhesive layer AL is the bottom layer of the workpiece Wk after transfer. In areas other than areas IMa and IMb of the image IM, layers of white ink WH and color inks CMYK are stacked on the adhesive layer AL, and the top layer of color inks CMYK is visible. Furthermore, by printing the white ink WH underneath the color inks CMYK, the color inks CMYK are clearly visible even when the workpiece Wk is dark or transparent. Furthermore, the light emitted by the phosphorescent pigment LP contained in the adhesive layer AL is blocked by the color inks CMYK. In areas IMa and IMb of the image IM, layers of white ink WH and clear ink CL are laminated on the adhesive layer AL, so in areas IMa and IMb of the image IM, the luminescence of the phosphorescent pigment LP contained in the adhesive layer AL passes through the layers of white ink WH and clear ink CL and becomes visible.

[0055] In this way, in the third example of the printing process, it is possible to add a luminous function to any area of ​​the image IM printed with the color inks CMYK. For example, it is possible to apply luminous paint to small or detailed areas that are difficult to apply manually, so it is possible to meet the diverse needs of users. In the color printing process, white ink WH may be printed instead of clear ink CL in the areas IMa and IMb of image IM. In a third example of the printing process, effect pigments may be mixed with hot melt powder HP as functional powder FP in the lamination process. In this case, clear ink CL may be printed in the white printing process in the areas of image IM that overlap areas IMa and IMb.

[0056] As described above, the transfer method described in the embodiment includes, for example, the following steps. (1) The transfer method includes a printing step (step S01), a powder application step (application step, step S02), and a pressing step (step S04). In the printing process, an image IM is printed on a medium M with ink. In the powder application step, hot melt powder HP (adhesive material) mixed with functional powder FP is applied to the image IM on the medium M. In the pressing step, the printed surface of the image IM on the medium M is placed on the workpiece Wk and pressed, thereby transferring the image IM to which the adhesive layer AL formed by the hot melt powder HP has been applied onto the workpiece Wk.

[0057] Moreover, the transfer system 1 described in the embodiment has, for example, the following configuration. (12) The transfer system 1 includes a printer 2 (printing device), a shaker 4 (adhesive applying device), and a heat press 8 (pressing device). The printer 2 prints an image IM on a medium M using ink. The shaker 4 applies the hot melt powder HP (adhesive) mixed with the functional powder FP to the image IM on the medium M. The heat press machine 8 presses the printed surface of the image IM of the medium M onto the workpiece Wk, thereby transferring the image IM to which the adhesive layer AL formed by the hot melt powder HP has been applied onto the workpiece Wk.

[0058] In DTF, the added value of printed materials can be increased by using functional powder FPs such as phosphorescent pigments and effect pigments in addition to inks containing general pigments. However, functional powder FPs generally have large particle sizes, making them difficult to print onto film using a regular inkjet printer. For example, it is possible to apply the functional powder FP to the printed material in a separate process, such as by hand, after transfer using DTF, but this could increase the number of steps required to manufacture the printed material.

[0059] In this embodiment, functional powder FP is mixed with hot melt powder HP, which is applied to the image IM in the powder application process. In the heating process, the hot melt powder HP is melted, and an adhesive layer AL containing the functional powder FP is formed on the image IM. In the pressing process, the adhesive layer AL and the image IM are transferred to the workpiece Wk, thereby applying the functional powder FP to the workpiece Wk. In other words, in this embodiment, the functional powder FP can also be applied to the workpiece Wk by performing a series of steps in the transfer method, thereby increasing the added value of the printed matter while minimizing increases in manufacturing man-hours. For example, in the printing process, an image IM is printed using white ink WH or clear ink CL, and in the powder application process, hot melt powder HP mixed with functional powder FP is applied to the image IM (see Figure 4, first example). As a result, in the workpiece Wk after transfer, the functional powder FP contained in the bottom adhesive layer AL becomes visible through the white ink WH or clear ink CL. In other words, a printed product can be produced in which the effect of the functional powder FP is applied to the entire surface of the image IM.

[0060] In the embodiment, an example in which hot melt powder HP is used as the adhesive has been described, but any adhesive can be used as long as it can be attached to the image IM and can transfer the image IM to the workpiece Wk. For example, a paste or gel adhesive can be applied to the image IM. Furthermore, if such an adhesive can form an adhesive layer AL without heating, the powder fixing step (step S03) in which the medium M is heated to melt the hot melt powder HP and fix it to the image IM can be omitted.

[0061] (2) In the transfer method, for example, in the powder application step, hot melt powder HP mixed with phosphorescent pigment LP (phosphorescent powder) can be applied to the image IM. The printing process includes, for example, a white printing process and a color printing process (see FIG. 5, second example). In the white printing process, white ink WH is printed over the entire area IA of the medium M where the image IM is to be printed. In the color printing process, a masking area MK that blocks the light emission from the phosphorescent pigment LP is printed with color inks CMYK within the area IA where the white ink WH has been printed.

[0062] In this way, in the printing process, white ink WH, which transmits the luminescence of the luminescent pigment LP contained in the adhesive layer AL, is printed over the entire area IA of the image IM, and then color inks CMYK are printed as masking areas MK in the areas where the luminescence should be blocked. This makes it possible to add luminescence functionality to desired areas of the image IM, making it possible to express complex characters and figures using the luminescent pigment LP.

[0063] (3) In the color printing process, the areas IA printed with the white ink WH other than the masking portions MK can be printed with the white ink WH or the clear ink CL (see (e) of FIG. 5).

[0064] This makes the thickness of the image IM after transfer onto the workpiece Wk uniform over the entire surface, making it possible to smooth the surface of the printed matter.

[0065] (4) The printing process includes, for example, a color printing process and a white printing process (see FIG. 6, third example). In the color printing process, an image IM is printed on a medium M using inks including color inks CMYK. In the white printing process, white ink WH is printed over the image IM printed in the color printing process. In the powder application process, hot melt powder HP, which is a mixture of functional powder FP such as phosphorescent pigments and effect pigments, is applied to the white ink WH printed in the white printing process. In the color printing process, the areas of the image IM other than the areas IMa and IMb (areas that block the functional powder FP) are printed with color inks CMYK, and the areas IMa and IMb that transmit the functional powder FP are printed with clear ink CL or white ink WH.

[0066] In the color printing process where an image IM is printed with color inks CMYK, by printing the areas that transmit the functional powder FP with clear ink CL, it is possible to impart the effects of the functional powder FP to any area of ​​the image IM after it has been transferred to the workpiece Wk. For example, it is possible to apply the luminous powder to small or detailed areas that are difficult to apply manually, so it is possible to meet the diverse needs of users.

[0067] (5) Effect pigments can be used as functional powders (FP). In a third example of the printing process, in a white printing process, clear ink CL can be printed in the areas of the image IM that overlap with the areas IMa and IMb that transmit the effect pigment.

[0068] This makes it easier to see the effect pigment contained in the adhesive layer AL located at the bottom after transfer onto the workpiece Wk.

[0069] <Variation 1> The transfer method (method for manufacturing a printed matter) according to variant example 1 includes a first transfer step of transferring an image IM1 (second image) printed with color inks CMYK onto a workpiece Wk, and a second transfer step of transferring an image IM2 (first image) printed with clear ink CL and having functional powder FP added onto the workpiece Wk. FIG. 7 is a flowchart showing the details of the first transfer step. FIG. 8 is a flowchart showing the details of the second transfer step. FIG. 9 is a diagram showing a transfer example of the first modification. 9(a) is a diagram showing the workpiece Wk after the first transfer process. FIG. 9(b) shows the image IM2 printed on the medium M in the second transfer process. FIG. 9(c) is a diagram showing the workpiece Wk after the second transfer process. FIG. 9(d) is a cross-sectional view taken along line AA in FIG. 9(c). The configuration of the transfer system 1 of the first modification is the same as that of the embodiment (see FIG. 1), and therefore a detailed description thereof will be omitted.

[0070] As shown in FIG. 7, the first transfer process includes a color printing process (step S101), a white printing process (step S102), a powder application process (step S103), a powder fixing process (step S104), a pressing process (step S105), and a peeling process (step S106). In the color printing process, printer 2 (see FIG. 1) prints an image IM1 (see FIG. 9(a)) on medium M using inks including color inks CMYK. In the white printing process, printer 2 prints white ink WH over the image IM1 printed in the color printing process. In the powder application step, a shaker 4 applies hot melt powder HP to the image IM1 printed on the medium M. In the powder fixing step, the medium M is heated to fix the hot melt powder HP to the image. This forms an adhesive layer AL on the image IM1. In the powder application step of the first transfer step, the functional powder FP does not need to be mixed with the hot melt powder HP. In the pressing step, the printed surface of the image IM1 of the medium M is placed on the workpiece Wk, and the medium M and the workpiece Wk are pressed together using a heat press 8 to transfer the image IM1 to the workpiece Wk. In the peeling step, the medium M is peeled off from the workpiece Wk.

[0071] As shown in (a) of Figure 9, in the first transfer step, an image IM1 shown by a solid line in (a) of Figure 9 is transferred onto a workpiece Wk. An image IM2 (shown by a dashed line) that is transferred in the second transfer step is added to the image IM1, thereby producing the final printed matter.

[0072] As shown in FIG. 8, the second transfer process includes a clear printing process (step S201), a powder applying process (step S202), a powder fixing process (step S203), a pressing process (step S204), and a peeling process (step S205). In the clear ink printing step, the printer 2 prints an image IM2 (see FIG. 9(b)) on the medium M using ink containing clear ink CL. In the powder fixing process, a shaker 4 is used to attach hot melt powder HP, which is mixed with functional powder FP, to the image IM2. In the powder fixing process, the media M is heated to fix the hot melt powder HP to the image IMG2. This forms an adhesive layer AL on the image IM2. The adhesive layer AL contains the functional powder FP. In the pressing process, the printed surface of image IM2 on medium M is superimposed on the area of ​​workpiece Wk to which image IM1 has been transferred. Specifically, image IM2 printed on medium M is aligned so that it overlaps the position indicated by the dashed line in FIG. 9(a). By pressing medium M and workpiece Wk together using a heat press 8 (see FIG. 1), image IM2 is transferred to workpiece Wk as shown in FIG. 9(c). In the peeling process, the film is peeled off from workpiece Wk. As shown in Figure 9(d), in the workpiece Wk, the image IM1 has a layer of white ink WH and a layer of color inks CMYK laminated on an adhesive layer AL that does not contain functional powder FP. That is, in the image IM1, the color inks CMYK in the top layer are visible. Furthermore, the presence of the layer of white ink WH underneath the color inks CMYK improves the visibility of the color inks CMYK. In the portion of image IM2, a layer of clear ink CL is laminated on top of an adhesive layer AL containing functional powder FP, so the functional powder FP can be seen through the layer of clear ink CL.

[0073] In this way, in Modification 1, an image IM2 that makes the functional powder FP visible is transferred onto a workpiece Wk onto which an image IM1 printed with CMYK color inks has been previously transferred. Modification 1 allows the image IM1 of the CMYK color inks and the image IM2 of the functional powder FP to be formed independently, for example, when they are not integrated, thereby improving the quality of the printed matter. In addition, in Modification 1, it is only necessary to mix the functional powder FP into the hot melt powder HP in the second transfer step of transferring the image IM2 to the workpiece Wk. Therefore, when the image IM1 of the CMYK color inks occupies a large area in the printed matter, the amount of functional powder FP used can be reduced, thereby reducing manufacturing costs.

[0074] Note that the image IM1 of the CMYK color inks and the image IM2 of the functional powder FP are only required to be ultimately transferred onto the same workpiece Wk, so the order of the first and second transfer steps is not limited, and the second transfer step may be performed before the first transfer step.

[0075] As described above, the transfer method according to the first modification includes, for example, the following steps. (6) The second transfer process includes a clear printing process (printing process, step S201), a powder application process (step S202), and a pressing process (step S204). In the clear ink printing step, an image IM2 (first image) is printed on the medium M with clear ink CL. In the powder application step, a hot melt powder HP mixed with a functional powder FP is applied to the image IM2. In the pressing step, an image IM2 of the medium M is superimposed and pressed in an area of ​​the workpiece Wk to which an image IM1 (second image) printed with inks including color inks CMYK has been applied.

[0076] In this way, an image IM2 that allows the functional powder FP to be visually recognized is transferred onto a workpiece Wk onto which an image IM1 printed with CMYK color inks has been previously transferred. For example, in cases where the image IM1 of the CMYK color inks and the image IM2 of the functional powder FP are not integrated, each image can be formed independently, thereby improving the quality of the printed matter.

[0077] (7) The first transfer process includes a color printing process (step S101), a white printing process (step S102), a powder application process (second application process, step S103), and a pressing process (second pressing process, step S105). In the color printing process, an image IM1 (second image) is printed on a medium M with inks including color inks CMYK. In the white printing process, white ink WH is printed over the image IM1 printed in the color printing process. In the powder application step, hot melt powder HP not mixed with functional powder FP is applied to the white ink WH printed in the white printing step. In the pressing step, the printed surface of the image IM1 of the medium M is placed on the workpiece Wk and pressed, thereby transferring the image IM1, on which the adhesive layer AL formed by the hot melt powder HP is laminated, to the workpiece Wk.

[0078] By providing separate transfer processes for the CMYK color ink image IM1 and the functional powder FP image IM2, there is no need to mix the functional powder FP with the hot melt powder HP in the first transfer process. In cases where the CMYK color ink image IM1 occupies a large area on the printed matter, the amount of functional powder FP used can be reduced, thereby cutting manufacturing costs.

[0079] <Variation 2> In the transfer method according to the second modification, the functional powder FP is not mixed with the hot melt powder HP, but is applied to the image by itself. FIG. 10 is a flowchart showing a transfer method according to the second modification. FIG. 11 is a diagram showing a transfer example of the second modification. Fig. 11(a) shows an image IM3 printed on the medium M in the clear printing process and an image IM4 printed in the color printing process. Fig. 11(b) is a diagram illustrating the detection of the mark mk by the sensor 25 of the printer 2. Fig. 11(c) is a cross-sectional view of the image IM3 and the image IM4 after they have been transferred to the workpiece Wk. The transfer system 1 that executes the transfer method according to Modification 2 can have the same configuration as the embodiment (see FIG. 1). In FIG. 11, the printer 2, the medium M, and the workpiece Wk are shown in a simplified form.

[0080] As shown in FIG. 10, the transfer method according to variant example 2 includes a clear printing process (first printing process, step S301), a first application process (step S302), a color printing process (second printing process, step S303), a white printing process (third printing process, step S304), and a second application process (step S304). In the clear ink printing step, an image IM3 (first image, see FIG. 11(a)) to which the functional powder FP is applied is printed on the medium M with clear ink CL by the printer 2 (see FIG. 1). Furthermore, in the clear printing step, a mark mk indicating the area where the image IM3 is printed (hereinafter referred to as the "printed area PA") is printed on the medium M with ink that can be detected by the sensor 25 (for example, color inks CMYK).

[0081] As shown in (a) of FIG. 11, the mark mk can be printed, for example, at the four corners of the printing area PA so as to surround the image IM3 printed in the printing area PA. The mark mk can be, for example, L-shaped, including a line segment S1 extending in one direction (for example, the X direction) and a line segment S2 connecting to one end of the line segment S1 and extending in a direction perpendicular to the line segment S1 (for example, the Y direction). The shape of the mark mk is not limited to this, and it can also be, for example, a cross shape where the line segments S1 and S2 intersect. The mark mk can also be, for example, only the line segment S1 or only the line segment S2.

[0082] In the first application step, functional powder FP is applied to image IM3 printed with clear ink CL. In the first application step, the functional powder FP can be applied to image IM3 alone without being mixed with hot melt powder HP. The first application step can be performed using a shaker 4 (see FIG. 1), similar to the powder application step of the embodiment. In this case, only the functional powder FP is supplied to the medium M from the application unit 41 of the shaker 4. Furthermore, heating by the heater 46 in the shaker 4 can be omitted. Alternatively, the first application step can be performed manually.

[0083] In the second modification, the medium M after the first application step is removed from the take-up unit 47 of the shaker 4 and set back into the printer 2, where the color printing step is performed. In the color printing step, the printer 2 prints an image IM4 (second image) in the printing area PA of the image IM3 on the medium M using inks including the color inks CMYK. Here, when images IM3 and IM4 are combined to form a single printed piece, image IM4 needs to be printed at the appropriate printing position (the position indicated by the dashed line in (a) of Figure 11) relative to the previously printed image IM3.

[0084] However, in the color printing process, the medium M is reset in the printer 2, and so there may be misalignment or tilting with respect to the medium M in the clear printing process. In particular, when the printer 2 unrolls and prints on a roll of medium M, misalignment or tilting is likely to occur.

[0085] As shown in FIG. 11(b), in Modification 2, when performing the color printing process, the printer 2 detects the mark mk printed on the medium M using the sensor 25. As described above, the mark mk indicates the printing area PA of the image IM3. That is, the printer 2 can calculate the positional shift and tilt of the printing area PA of the image IM3 based on the mark mk detected by the sensor 25. The printer 2 adjusts the ink ejection position for printing the image IM4 based on the calculated positional shift and tilt. This allows the image IM4 to be printed at an appropriate position within the printing area PA of the image IM3.

[0086] In the white printing step, the printer 2 prints white ink WH over the images IM3 and IM4. In the second application step, the hot melt powder HP is applied to the images IM3 and IM4 by the shaker 4. In the second application step, it is not necessary to mix the functional powder FP with the hot melt powder HP. In the second application step, the heater 46 of the shaker 4 is driven. That is, as in the embodiment, the powder fixing step (FIG. 10, step S306) is performed to melt and fix the hot melt powder HP attached to the images IM3 and IM4.

[0087] Furthermore, by performing the pressing step and peeling step (steps S306 and S307) in the same manner as in the embodiment, the images IM3 and IM4 are transferred from the medium M to the workpiece Wk. As shown in Figure 11(d), in the workpiece Wk, the image IM3 portion has a layer of functional powder FP and a layer of clear ink CL stacked on top of a layer of adhesive layer AL and white ink WH. The functional powder FP is visible through the layer of clear ink CL. Furthermore, the presence of a layer of white ink WH underneath the functional powder FP improves the visibility of the functional powder FP. In the image IM4, a layer of white ink WH and a layer of color inks CMYK are laminated on an adhesive layer AL that does not contain functional powder FP. That is, in image IM4, the color inks CMYK in the top layer are visible. Furthermore, the presence of a layer of white ink WH underneath the color inks CMYK improves the visibility of the color inks CMYK. In this way, in the transfer method of Modification 2, the functional powder FP is applied to the image IM3 without being mixed with the hot melt powder HP, so it is possible to apply a large amount of functional powder FP. In other words, the transfer method of Modification 2 is suitable for use when it is desired to maximize the decorative and luminous functions of the functional powder FP in the printed matter.

[0088] As described above, the transfer method according to the second modification includes, for example, the following steps. (8) The transfer method includes a clear printing step (first printing step), a first applying step, a color printing step (second printing step), and a second applying step. In the clear ink printing step, an image IM3 (first image) is printed on the medium M with clear ink CL. In the first application step, the functional powder FP is applied to the image IM3. In the color printing process, an image IM4 (second image) is printed in the printing area PA of the medium M where the image IM3 is printed, using inks containing the color inks CMYK (inks containing pigments). In the second application step, the hot melt powder HP is applied to the images IM3 and IM4 on the medium M.

[0089] In this way, in Variation 2, the functional powder FP can be applied only to the portion of the printed matter where the functionality of the functional powder FP is to be imparted (image IM3), and the functional powder FP can be applied without being mixed with the hot melt powder HP. In other words, this is suitable for situations where you want to maximize the decorative and luminous functions of the functional powder FP while reducing the amount of functional powder FP used.

[0090] (9) In the clear printing step, a mark mk is printed on the medium M to indicate the printing area PA, which is the area where the image IM3 is printed. In the color printing process, the position where the image IM4 is printed is adjusted based on the mark mk.

[0091] For example, after the first application step, the medium M is removed from the take-up unit 47 of the shaker 4 and reset in the printer 2 for the color printing step. At this time, tilt or misalignment of the medium M may occur. The printer 2 detects the mark mk, for example, using the sensor 25, and adjusts the printing position of the image IM4 based on the position and tilt of the mark mk, thereby making it possible to print the image IM4 in the appropriate position.

[0092] (10) The transfer method according to the second modification may include a white printing step (third printing step) between the color printing step and the second application step, in which white ink WH is printed over the images IM3 and IM4.

[0093] By forming a layer of functional powder FP for image IM3 and a layer of white ink WH under the layer of color ink CMYK for image IM4, the visibility of images IM3 and IM4 can be improved even when the workpiece Wk is dark colored or transparent.

[0094] The present invention is not limited to the above-described embodiments and modifications, and can be modified as appropriate within the scope of the technical concept of the present invention. Furthermore, the modifications may not only be applied to the embodiments, but at least a portion of each of the modifications may also be applied to other modifications. Furthermore, the effects described regarding the transfer method also apply to the transfer system 1 that executes the transfer method and the method for manufacturing printed matter.
