[0013] Embodiment 1.

[0014] [Printed Material (100)]

[0015] FIG. 1 is an enlarged perspective view schematically showing an example of a printed material (100) related to Embodiment 1. FIG. 2 is an enlarged plan view schematically showing an example of a printed material (100) related to Embodiment 1. FIG. 3 is an enlarged cross-sectional view schematically showing an example of a printed material (100) related to Embodiment 1. FIG. 3 is a cross-sectional view of the cross-section at the AA line position of the printed material (100) shown in FIG. 2, viewed in the direction of the arrow. As shown in FIG. 1 to FIG. 3, the printed material (100) is an article in which printing is performed on the surface of a substrate (10).

[0016] The printed material (100) is an article that has a three-dimensional embossed shape, such as so-called embossing. When forming this three-dimensional embossed shape, embossing processing is used, for example. When forming or press-processing plastic or metal constituting the article, a process of forming a fine shape (embossing) on ​​the surface of a mold (molding or press mold) and transferring that shape to the molded product is called "embossing processing," and that shape is called "embossing." That is, embossing processing is one of the surface treatments that physically forms a wrinkle shape (embossing).

[0017] Shapes include, for example, leather (scales), pear shell, wood grain, rock grain, sand grain, fabric grain and silk grain (fabric shape), geometric shapes, etc. Additionally, by forming an embossed shape on an article, value such as ornamentation or function can be added to the exterior of the article, for example. For example, by forming an embossed shape on an article, the appearance of the article can be changed to create a sense of luxury, the texture can be changed to improve tactile sensation, slip resistance can be prevented, and dirt (fingerprints) or scratches can be made less visible.

[0018] The printed material (100) comprises a substrate (10) having a three-dimensional embossed shape (121) formed on its surface, and an ink portion (20) printed on the embossed shape (121), which is composed of ink printed on the substrate (10). The printed material (100) forms an decorative layer in which various designs such as characters, figures, shapes, images, and colors are implemented by decoration by the embossed shape (121) and decoration by the ink portion (20). The substrate (10) is printed directly or indirectly by the ink portion (20).

[0019] (Information (10))

[0020] The substrate (10) is mainly a product such as a synthetic resin such as plastic, but is not limited to a resin product and may be a product of other materials such as a metal product, for example. The substrate (10) may be a solid member, a plate member, or a thin film member such as a film. Also, the substrate (10) may be a three-dimensional curved member in addition to a flat member.

[0021] The substrate (10) has a three-dimensional uneven shape (121) formed on its surface. The uneven shape (121) constitutes a three-dimensional uneven shape decoration, such as the embossing described above. The uneven shape (121) forms, for example, the leather (scale), pear shell, wood grain, rock grain, sand grain, fabric grain, and silk grain (fabric shape) described above. By forming the uneven shape (121) on the substrate (10), as described above, the appearance of the article can be changed to create a sense of luxury, the texture can be changed to improve tactile sensation, slipping can be prevented, and dirt (fingerprints) or scratches can be made less noticeable.

[0022] The uneven shape (121) of the reference surface (10) is formed by at least one of a reference surface portion (11) that constitutes the reference surface, a plurality of convex portions (12) formed in a shape protruding from the reference surface portion (11), and a plurality of concave portions (13) formed in a shape recessed from the reference surface portion (11) (see FIG. 7). The reference surface portion (11) is formed in a planar or curved shape. In addition, the reference surface portion (11) may have three-dimensional uneven portions in addition to the convex portions (12) and concave portions (13). In the printed material (100) related to embodiment 1, as shown in FIGS. 1 to 3, the uneven shape (121) of the substrate (10) is formed by a reference surface portion (11) of the substrate (10) and a plurality of convex portions (12) of the substrate (10).

[0023] In FIG. 2, the convex portion (12) is formed in a rectangular shape when viewed from a planar view, but the shape of the convex portion (12) is not limited to this shape. The convex portion (12) may be formed in a three-dimensional shape, and for example, when viewed in a direction perpendicular to the substrate (10), it may be formed in a square shape, a circular shape, a polygonal shape, or a shape other than a rectangle, such as a specific shape or a character. Also, when viewed in a direction perpendicular to the substrate (10), the convex portion (12) may be formed in a straight line or in a curved shape. Also, the upper portion (12a) of the convex portion (12) may be formed in a flat shape or in a curved shape. Also, the upper portion (12a) of the convex portion (12) may have a three-dimensional uneven surface.

[0024] (Ink part (20))

[0025] The ink portion (20) is a portion of the printed material (100) where ink is placed. The ink portion (20) is a portion formed by the ink printed on the substrate (10).

The ink portion (20) is printed on the uneven shape (121) of the substrate (10).

[0026] The ink section (20) is formed by printing. The ink section (20) may be formed by so-called dot-like particle printing, or by so-called plain printing. Plain printing is a printing method in which a predetermined printing area of ​​the printing surface is completely covered with ink without gaps.

[0027] The ink portion (20) is printed only on the uneven shape (121). The ink portion (20) is printed only on the convex portion (12) that constitutes the uneven shape (121) (see FIG. 1). Or, the ink portion (20) is printed only on the concave portion (13) that constitutes the uneven shape (121) (see FIG. 7). Or, the ink portion (20) is printed only on the convex portion (12) and the concave portion (13) that constitute the uneven shape (121) (see FIG. 13). The ink portion (20) is not printed on the reference surface portion (11).

[0028] The ink portion (20) is printed on at least part of the plurality of convex portions (12) (see FIG. 4). That is, the ink portion (20) is printed on part or all of the plurality of convex portions (12). Alternatively, the ink portion (20) is printed on at least part of the plurality of concave portions (13) (see FIG. 10). That is, the ink portion (20) is printed on part or all of the plurality of concave portions (13). Alternatively, the ink portion (20) is printed on at least part of the plurality of convex portions (12) and at least part of the plurality of concave portions (13) (see FIG. 16).

[0029] The ink part (20) forms a decoration such as a shape in the printed material (100). The ink part (20) forms a decoration printed on the embossed shape (121) of the substrate (10). The ink part (20) provides additional decoration such as a shape in the embossed shape (121) of the substrate (10) that forms the decoration. The decoration by the ink part (20) forms various designs such as, for example, letters, figures, colors, and shapes. The decoration by the ink part (20) adds additional decoration to the decoration by the embossed shape (121). For example, the shape, etc. formed by the ink part (20) forms a shape, etc. that is different from the shape, etc. formed by the embossed shape (121).

[0030] Among the plurality of convex parts (12), the ink part (20) placed on the upper part (12a) of at least some of the convex parts (12) is called the convex ink part (20a). Also, in the printed material (100) related to Embodiment 1, the convex ink part (20a) is placed on the upper part (12a) of all the convex parts (12) of the plurality of convex parts (12). In the printed material (100) related to Embodiment 1, the ink part (20) is composed of the convex ink part (20a).

[0031] In addition, the ink portion (20) in the printed material (100) is composed of at least one of a convex ink portion (20a) (see FIG. 1) and a concave ink portion (20b) (see FIG. 7).

The printed material (100), for example, can impart a sense of luxury to the printed material (100) by means of the embossed shape (121) of the substrate (10) alone. The printed material (100) can impart an additional sense of luxury beyond that imparted by the substrate (10) alone by means of decoration by the ink portion (20) on the embossed shape (121) through printing. The printed material (100) can produce a synergistic effect between the decoration by the embossed shape (121) and the decoration by the printed ink portion (20) regarding decorations such as a sense of luxury. Also, since the decoration by printing can be performed at a relatively low cost, the printed material (100) can add additional decoration to the three-dimensional embossed shape (121) of the substrate (10) at the lowest possible cost through the above configuration.

[0035] Additionally, the ink portion (20) forms a decoration printed on the uneven shape (121) of the substrate (10). The printed material (100) can produce a synergistic effect between the decoration by the uneven shape (121) and the decoration by the printed ink portion (20) regarding decorations such as a sense of luxury.

[0036] Additionally, the uneven shape (121) of the substrate (10) is formed by a reference surface portion (11) and a plurality of convex portions (12). The ink portion (20) is composed of a convex ink portion (20a). By the above configuration, the printed material (100) has a convex ink portion (20a) printed on the uneven shape (121), thereby allowing additional decoration to be applied to the three-dimensional uneven shape (121) of the substrate (10) at the lowest possible cost. With regard to decoration such as a sense of luxury, the printed material (100) can produce a synergistic effect between the decoration by the uneven shape (121) and the decoration by the printed convex ink portion (20a).

[0037] Additionally, the convex ink portion (20a) is placed on the upper portion (12a) of all convex portions (12) of the plurality of convex portions (12). By the above configuration, the printed material (100) has a convex ink portion (20a) printed on the uneven shape (121), thereby allowing additional decoration to be applied to the three-dimensional uneven shape (121) of the substrate (10) at the lowest possible cost. With regard to decoration such as a sense of luxury, the printed material (100) can produce a synergistic effect between the decoration by the uneven shape (121) and the decoration by the printed convex ink portion (20a).

[0038] Also, the substrate (10) is, for example, a synthetic resin. Recently, mold manufacturing technology has improved, so when the substrate (10) is a synthetic resin, for example, an uneven shape (121) with a complex shape can be formed on the substrate (10) by injection molding, etc.

[0065] For components having the same function and operation as the printed material (100) related to embodiments 1 to 4, the same reference numerals are assigned and their descriptions are omitted. Hereinafter, using FIGS. 13 to 15, etc., the configuration of embodiment 5 will be described focusing on the differences from embodiments 1 to 4. Also, configurations not described in embodiment 5 are identical to those of embodiments 1 to 4. The printed material (100) related to embodiment 5 has a configuration of the uneven shape (121) that is different from the printed material (100) of embodiments 1 to 4.

[0066] The substrate (10) has a three-dimensional uneven shape (121) formed on its surface. The uneven shape (121) of the substrate (10) is formed by a reference surface portion (11) that constitutes a reference surface, a plurality of convex portions (12) (see FIG. 1) formed in a shape protruding from the reference surface portion (11), and a plurality of concave portions (13) formed in a shape recessed from the reference surface portion (11) and the reference surface portion (11).

By the above configuration, the printed material (100) has a convex ink portion (20a) and a concave ink portion (20b) printed on the uneven shape (121), thereby allowing additional decoration to be applied to the three-dimensional uneven shape (121) of the substrate (10) at the lowest possible cost. The printed material (100) can produce a synergistic effect with respect to decorations such as a sense of luxury, with decorations made of an embossed shape (121) and decorations made of printed convex ink parts (20a) and concave ink parts (20b).

[0071] Additionally, the printed material (100) has a convex ink portion (20a) and a concave ink portion (20b) printed on the uneven shape (121) by the above configuration, thereby allowing additional decoration to be applied to the three-dimensional uneven shape (121) of the substrate (10) at the lowest possible cost. The printed material (100) can produce a synergistic effect with respect to decorations such as a sense of luxury, between the decoration by the uneven shape (121) and the decoration by the printed convex ink portion (20a) and the concave ink portion (20b).

[0072] In addition, the printed material (100) can express more complex shapes, etc. compared to the case where the ink portion (20) is placed on either the convex portion (12) or the concave portion (13) by the above configuration. Also, since the printed material (100) related to Embodiment 5 includes the configuration of the printed material (100) of Embodiment 1, it can produce the same effect as the printed material (100) of Embodiment 1.

[0075] For components having the same function and operation as the printed material (100) related to embodiments 1 to 5, the same reference numerals are assigned and their descriptions are omitted. Hereinafter, using FIGS. 16 to 18, etc., the configuration of embodiment 6 will be described focusing on the differences from embodiments 1 to 5. Also, configurations not described in embodiment 6 are identical to those in embodiments 1 to 5. The printed material (100) related to embodiment 6 has an arrangement of ink portions (20) that is different from the printed material (100) of embodiment 5.

[0076] As shown in FIGS. 16 to 18, in the printed material (100) related to Embodiment 6, the convex ink portion (20a) is placed on the upper portion (12a) of some of the convex portions (12) among the plurality of convex portions (12). As described above, in the printed material (100) related to Embodiment 5, the convex ink portion (20a) is placed on the upper portion (12a) of all of the convex portions (12) among the plurality of convex portions (12).

[0077] As shown in FIGS. 16 to 18, in the printed material (100) related to embodiment 6, the concave ink portion (20b) is placed on the bottom portion (13a) of some of the concave portions (13) among the plurality of concave portions (13). As described above, in the printed material (100) related to embodiment 5, the concave ink portion (20b) is placed on the bottom portion (13a) of all of the concave portions (13) among the plurality of concave portions (13). In contrast, the printed material (100) related to embodiment 6 has a concave portion (13) where the concave ink portion (20b) is placed and a concave portion (13) where the concave ink portion (20b) is not placed.

[0078] In the printed material (100) of embodiment 6, the convex ink portion (20a) may be placed on the upper portion (12a) of at least some of the convex portions (12) of the plurality of convex portions (12). Also, in the printed material (100) of embodiment 6, the concave ink portion (20b) may be placed on the bottom portion (13a) of at least some of the concave portions (13) of the plurality of concave portions (13).

Using FIG. 19 and FIG. 20, an example of a printing device (200) for printing on a substrate (10) and a method for manufacturing a printed material (100) will be described. Components having the same function and operation as the printed material (100) related to Embodiments 1 to 6 are given the same reference numerals and their descriptions are omitted. Additionally, components not described in Embodiment 7 are the same components as those in Embodiments 1 to 6.

[0083] [Printing device (200)]

[0084] The printing device (200) is a device that first transfers ink (25) on a printing plate (50) to a printing pad (30) composed of an elastic silicone pad, etc., and performs a second transfer to a printed object. In addition, the configuration of the printing device (200) described using FIG. 19 and FIG. 20 is an example and is not limited to the configuration shown.

[0085] [Printing pad (30)]

[0086] The printing device (200) is equipped with a printing pad (30). The printing pad (30) is used to transfer ink (25) (see FIG. 20) on a printing plate (50) to the surface to be printed on a substrate (10). The printing pad (30) shown in FIG. 20 is formed, for example, in a roughly hemispherical shape. The shape of the printing pad (30) is not limited to this, and the shape can be appropriately changed according to the specifications of the substrate (10) (see FIG. 1) having the surface to be printed. The shape of the printing pad (30) can be formed, for example, as a projectile shape, a shape having a curved surface formed by rotating a parabola around its axis of symmetry, a shape such as a part of an ellipsoid cut, or a shape formed by continuously extending a cross-section of a projectile shape or a semicircle shape in a straight line.

[0087] The printing pad (30) is provided with a portion (36) that first contacts the substrate (10) or the printing plate (50), and the portion (36) is composed of a dot or a line. Thus, when the printing pad (30) is pressed against the substrate (10) or the printing plate (50), air is not drawn between the printing surface (34) and the substrate (10) or the printing plate (50). By this configuration, the printing pad (30) can prevent omissions from occurring in the printed image applied to the substrate (10). For example, among the surfaces of the printing pad (30), a predetermined area centered on the portion (36) becomes the printing surface (34) that transfers ink (25) from the printing plate (50) to the substrate (10).

[0088] The printing pad (30) has a body (35) and a support member (37). The body (35) is formed by molding, for example, silicone rubber. The body (35) has elasticity (flexibility) and is mixed with silicone oil to make it easy to deform. In FIG. 20, the body (35) is formed in a roughly hemispherical shape, but the shape can be appropriately changed according to the specifications of the substrate (10), etc.

[0089] The body (35) is deformed when the printing pad (30) is pressed against the printing plate (50), and transfers the ink (25) placed on the mounting surface (51) of the printing plate (50) to the printing surface (34). The ink (25) placed on the mounting surface (51) of the printing plate (50) is arranged in correspondence with the shape, etc., to be printed on the substrate (10), and forms a printing pattern according to the shape, etc. Additionally, the material of the body (35) is not limited as long as it can transfer the ink (25) to the printing surface when the printing pad (30) is pressed against the printing surface.

[0090] The body (35) may be formed from two materials with different hardnesses. For example, as shown in FIG. 20, the body (35) of the printing pad (30) may be provided with an inner layer (31) and an outer layer (32) covering the surface of the inner layer (31). In that case, for example, the material of the outer layer (32) constituting the part close to the printing surface (34) is set to a range of 5 to 20 points in Aska C hardness. And the material constituting the inner layer (31) located inside the outer layer (32) is set to an Aska C hardness of 20 to 40 points. The inner layer (31) is located on the side where a force is applied to press the printing surface (34) against the printing surface during printing with respect to the outer layer (32), and is located on the side of the support member (37) rather than the outer layer (32) as a whole.

[0091] The support member (37) is connected to the vertical movement device (41) and is a part that transmits force from the vertical movement device (41) to the printing pad (30). In FIG. 20, the upper part of the body (35) is set to an Asuka C hardness of 20 to 40 points, and the lower part of the body (35) (the side where the upper part (36) is located) is set to an Asuka C hardness of 5 to 20 points.

[0092] In order for the printing pad (30) to deform and follow the surface to be printed, it is desirable that the hardness of the printing pad (30) be set low. For this reason, the hardness of the part of the printing pad (30) on the printing surface (34) side that is pressed against the substrate (10) is set lower than the hardness of the upper part. By configuring the printing pad (30) in this way, the overall shape of the printing pad (30) is easily maintained. Along with this, the outer layer (32) that is directly pressed against the surface to be printed has the advantage of being easily deformed along the three-dimensional shape provided by the surface to be printed. However, the hardness of each part of the body (35) is not limited to the above hardness.

[0093] [Up and down movement device (41)]

[0094] The printing device (200) is equipped with an up-and-down movement device (41). The up-and-down movement device (41) moves the printing pad (30) up and down in a straight line as well.

[0095] The printing pad (30) moves up and down by means of an up-and-down movement device (41) provided by the printing device (200), and the printing surface (34) is pressed against a printing plate (50) on which ink (25) is placed. The ink (25) on the printing plate (50) is attached to the pressed printing surface (34). After that, the printing pad (30) moves horizontally by means of a horizontal movement device (42) provided by the printing device (200) and moves up and down by means of an up-and-down movement device (41), and the printing surface (34) is pressed against an uneven shape (121) (see FIG. 1) that becomes the printing surface of the substrate (10). The ink (25) attached to the printing surface (34) is attached to the uneven shape (121) of the substrate (10). The printed material (100) is formed such that the shape of the printing plate (50) by ink (25) is imprinted on the uneven shape (121) of the substrate (10), and an ink portion (20) is formed on the uneven shape (121) of the substrate (10).

[0096] [Horizontal movement device (42)]

[0097] The printing device (200) is equipped with a horizontal movement device (42). The horizontal movement device (42) moves the printing pad (30) and the vertical movement device (41) in a horizontal direction. The printing pad (30) moves upward by the horizontal movement device (42) above the substrate (10), the cleaning device (60), the activating device (61), the air blowing device (62), and the printing plate (50). The printing pad (30) moves up and down by the vertical movement device (41), and the printing surface (34) is pressed against each of the substrate (10), the cleaning device (60), the activating device (61), or the printing plate (50).

[0098] The printing device (200) shown in FIG. 19 has, from the left, a printing stage (87) on which a substrate (10) is placed, a surface treatment stage (86) equipped with a cleaning device (60), and a printing plate stage (85) on which a printing plate (50) is placed. On the printing stage (87), a substrate (10) is placed and a blower (66) is installed. On the surface treatment stage (86), a cleaning device (60), an activation device (61), and an air blow device (62), etc. are installed. On the printing plate stage (85), a printing plate (50) and an ink placement device (63), etc. are installed.

[0099] In the printing device (200), stages such as the printing stage (87), surface treatment stage (86), and printing plate stage (85) can be freely arranged and can be appropriately changed according to the conditions of the operator or the place where the printing device (200) is installed. Also, regarding the cleaning device (60), activation device (61), air blow device (62), blower (66), and blower (66A) of the printing device (200), there may be cases where they are not installed in the printing device (200).

[0100] The printing pad (30) moves between each stage, such as the printing stage (87), the surface treatment stage (86), and the printing plate stage (85), by means of the horizontal movement device (42) described above, as an example. Additionally, the printing method described above by the printing device (200) is an example and may be printed by other methods. For example, the printing device (200) may perform printing by fixing the printing pad (30) and moving each stage and each device, such as the printing stage (87), the surface treatment stage (86), and the printing plate stage (85), up and down. That is, the arrangement and movement method of each device constituting the printing device (200) described above is an example and is not limited to the arrangement and method described above.

[0101] [Blower (66)]

[0102] A blower (66) is installed on the printing stage (87). The printing device (200) is equipped with a blower (66) that sends air to the printing surface (34) when ink (25) is transferred to the printing surface (34) of the printing pad (30). The blower (66) blows air toward the printing surface (34) of the printing pad (30). In the printing device (200) shown in FIG. 19, the blower (66) is positioned around the area where the substrate (10) of the printing stage (87) is placed.

[0103] The blower (66) sprays air onto the printing surface (34) before it is pressurized on the printing surface of the substrate (10) with the ink (25) attached. By spraying air toward the printing surface (34), the blower (66) also evaporates liquids such as solvents that have permeated the ink (25) and the liquid attached to the printing surface (34) by the activation device (61). Due to the configuration of the printing pad (30), the affinity between the ink (25) and the printing surface (34) is reduced. Also, due to the configuration of the printing pad (30), the viscosity of the ink (25) increases. In short, the ink (25) is cured by the blowing of air by the blower (66) on the printing pad (30).

[0104] The blower (66) is positioned toward the printing surface (34) of the printing pad (30) before contacting the substrate (10) and toward the air outlet (not shown). The blower (66) may be installed at multiple points so that air comes into contact with the printing surface (34). Additionally, the blower (66) may be equipped with a heater (not shown) inside to adjust the temperature of the air sent to the printing surface (34).

[0105] The temperature of the air sent to the printing surface (34) may be adjusted by detecting the temperature of the air sent to the printing surface (34) by a temperature sensor (68) and adjusting the output of a heater (not shown). Alternatively, the temperature sensor (68) may detect the room temperature of the environment in which the printing device (200) is placed and adjust the output of the heater according to the room temperature.

[0106] The blower (66) shown in FIG. 19 may be formed on the printing stage (87) or elsewhere. The blower (66) may be formed on the surface treatment stage (86), for example, as in the blower (66A) shown in FIG. 19. The printing pad (30) on which the ink (25) has been transferred is controlled to move the printing surface (34) forward of the blower port of the blower (66) before being pressed against the substrate (10), so that air from the blower (66) comes into contact with the printing surface (34). Additionally, the printing device (200) may be equipped with either the blower (66) or the air blow device (62) described later, and the blower (66) may function as the air blow device (62), or the air blow device (62) may function as the blower (66).

[0107] [Cleaning device (60)]

[0108] As shown in FIG. 19, a surface treatment stage (86) is positioned next to the printing stage (87) of the printing device (200). A cleaning device (60) is installed on the surface treatment stage (86). The cleaning device (60) is provided with, for example, paper or adhesive tape. The printing surface (34) of the printing pad (30) is pressed against the surface of the paper or adhesive tape, thereby removing ink (25), contaminants, or dust remaining after printing.

[0109] [Activation device (61)]

[0110] The activation device (61) is equipped with a reservoir for storing liquid and an absorption unit for absorbing and maintaining liquid. The printing surface (34) of the printing pad (30) is pressed against the surface of the absorption unit, thereby allowing the liquid maintained by the absorption unit to adhere to it. By attaching or allowing a liquid such as water or a solvent to the printing pad (30) or to permeate it into the gas (35), the ink (25) placed on the printing plate (50) becomes easier to transfer to the printing surface (34).

[0111] The liquid is appropriately selected according to the properties of the components included in the ink (25) and has the property of softening the hard ink (25). The ink (25) is a mixture of synthetic resins such as acrylic resin or urethane resin and water, thinner, xylene or toluene, and can be selected to have high affinity with the solvent included in the ink (25). However, the liquid used in the activation device (61) is not limited to the above.

[0112] The absorption unit of the activation device (61) is composed of, for example, a thin sheet of absorbent material. The absorbent material is composed of, for example, paper, but is not limited to paper; it may be composed of other materials such as cloth or resin as long as it absorbs liquid. For example, the absorption unit may be composed of paper laminated onto a sponge-like resin.

[0113] The surface of the absorbing unit to which the printing surface (34) of the printing pad (30) is pressed may be contaminated with ink (25) remaining on the printing surface (34) of the printing pad (30), or the surface of the absorbing unit may be scraped, causing the paper constituting the absorbing unit to tear. Therefore, the paper located on the top layer of the absorbing unit is configured to be peeled off and removed from the top layer of the absorbing unit, so that the stacked sheets can be removed one by one or the upper layer can be replaced mechanically. However, the method of replacing the paper located on the top layer is not limited to this method.

[0114] The absorption unit of the activation device (61) is configured so that the paper or the like constituting the top layer can be freely removed or replaced, and the surface is always kept clean and also permeated with liquid, so that when the printing surface (34) of the printing pad (30) is pressed, the printing surface (34) can be activated.

[0115] [Air blower device (62)]

[0116] The air blow device (62) adjusts the amount of liquid, such as water or solvent, attached to the printing surface (34) of the printing pad (30) by the activation device (61). The air blow device (62) sprays air toward the printing surface (34) and removes excess liquid, such as water or solvent, from the printing surface (34). Additionally, the type, quantity, and direction of air spraying of the air blow device (62) are not limited.

[0117] [Ink insertion device (63)]

[0118] The printing plate stage (85) has a printing plate (50) placed on its upper surface and is equipped with an ink placement device (63) for placing ink (25) on the printing plate (50). The ink placement device (63) is equipped with, for example, a roller (64) that holds the ink (25), and the roller (64) is driven on the printing plate (50) to place the ink (25) on the printing plate (50). The roller (64) is configured to rotate around a rotation axis (65).

[0119] The ink application device (63) may be an inkjet type head installed to move freely in a horizontal direction. In this case, the head is configured to apply ink (25) to the surface of the printing plate (50) by an inkjet method and to move along a moving rail. Also, the ink application device (63) may apply ink (25) to the surface of the printing plate (50) using a screen (not shown). Additionally, the ink application device (63) may not be limited to the above and may take other forms.

[0120] [Control device (90)]

[0121] As shown in FIG. 19, the printing device (200) is equipped with a control device (90). The control device (90) is configured, for example, as a microcomputer and is equipped with an arithmetic unit (90a) and a memory unit (90b). The function of the control device (90) is realized using the arithmetic unit (90a) and the memory unit (90b).

[0122] The memory device (90b) is a ROM that holds programs and data in advance, a RAM for temporarily storing data when a program is executed, etc. Also, as the memory device (90b), non-volatile or volatile semiconductor memory such as flash memory, EPROM (Erasable and Programmable ROM) and EEPROM (Electrically Erasable and Programmable ROM) is used.
