On the upper side, the monochrome intaglio print (3) in which the image line (22) made of monochromatic intaglio ink expresses the gradation with a height difference of about 10 to 70 μm in height (H), or FIG. As shown, the multicolor (three colors) intaglio ink image (24) expresses gradation and multicolor (three colors) with a height difference of about 10 to 70 μm in height (H). There is (4).

  As described above, the monochromatic or multicolor intaglio printed matter (3, 4) is difficult to reproduce in 1) the gradation expressed in the depth of the image line (photograph, etc.). 2) Fine lines such as micro characters can be obtained. 3) Technology and equipment are not generalized. 4) The unevenness of the ink can be easily distinguished by touch. 5) In multicolor intaglio printing, the effect of preventing counterfeiting is considered to be very high because the boundary lines of different colors are mixed somewhat (called rainbow printing).

  The intaglio printed matter, particularly the multicolor intaglio printed matter (4) is produced, for example, as shown in the side view of FIG. 1, on the circumferential surface of the rotating plate cylinder (30), the impression cylinder (32), A color ink landing roller (33A) (also referred to as color separation cylinder), B color ink landing roller (33B), C color ink landing roller (33C), and extra ink. Using a multicolor intaglio printing machine (100) in which wiping rollers (34) for wiping off are sequentially arranged in the circumferential direction (P), the plate cylinder (30) is rotated on a substrate (10) such as a sheet by one rotation. Color (three colors) intaglio printing is performed, which is a method called Zammel intaglio printing.

  As the multicolor intaglio printed matter (4) printed by the multicolor intaglio printing machine (100), for example, as shown in FIG. 13 (a), a concave pattern (20) of Δ ▽ is in the circumferential direction (P).

  The term “all solid” as used in claim 3 and claim 10 means that the entire surface of the printing plate is flat and the printing surface printed with the printing plate has no difference in density and no white portions and is completely covered with printing ink. The part that has been broken (print encyclopedia Japan Printing Society).

  Since this invention is the above structure, there exist the following effects.

  That is, according to the first aspect of the present invention, the ink is rotated on the plate surface of the plate cylinder having the concave pattern by rotating in the circumferential direction and surrounding the ink landing roller in which the portion where the ink is applied is a convex pattern. In the intaglio printed matter, the plate surface is wiped with a wiping roller, and the convex pattern ink that has been embedded in the concave pattern is transferred to the substrate by one rotation of the ink setting roller. The convex pattern has a predetermined width in the circumferential direction and is arranged at a constant pitch, and the convex pattern after the second rotation is in the circumferential direction with respect to the convex pattern of the first rotation. Since the convex pattern is formed so as to be shifted by a distance less than one pitch, an intaglio printed matter having a variable pattern having a high anti-counterfeit property can be provided by changing the pattern every rotation. Note that it is not preferable that the deviation of the convex pattern at the second and subsequent rotations with respect to the convex pattern at the first rotation is 1 pitch because the obtained pattern may not be a variable pattern.

  According to the second aspect of the present invention, the convex pattern is composed of a plurality of colors, and each of the plurality of colors is shifted from each other by one width of the convex pattern. It is possible to provide an intaglio printed matter having a multicolor variable pattern which is changed to a plurality of colors in addition to the pattern itself and has higher anti-counterfeiting properties and excellent design.

  According to the third aspect of the present invention, the convex pattern of the final color of the plurality of colors is formed as a solid pattern, that is, a convex pattern with a flat entire surface, so that a predetermined width is obtained. Therefore, it is not necessary to make the convex pattern arranged at a constant pitch, and it is not necessary to register it with the convex pattern of other colors. The intaglio printed matter having a good appearance can be obtained by complementing the gaps (due to misregistration) between the convex patterns before the color.

  Moreover, according to the invention which concerns on the said Claim 4, it can be set as the intaglio printed matter which has a variable pattern with a higher forgery prevention effect because at least 1 color of the said multiple colors consists of special ink.

  Furthermore, according to the invention according to claim 5, the special ink of claim 4 is a fluorescent intaglio ink or an infrared absorbing intaglio ink, so that it cannot be visually observed, and a black lamp or an infrared monitor is provided. Since the variable pattern can be visually recognized by use, it is possible to obtain an intaglio printed matter having a variable pattern with further improved forgery prevention.

  Further, according to the invention according to claim 6, by forming the concave pattern forming the plate surface of the plate cylinder in a lattice-like or deformed lattice-like design, the plate surface of the plate cylinder is a portion other than the concave pattern, that is, Since the non-image portion is almost eliminated, the number of variable patterns in combination with the convex pattern can be increased to a large number (close to an infinite number depending on the change in the period such as the shape of the lattice-shaped concave pattern and the number of frames). An intaglio printed matter having a variable pattern with improved anti-counterfeiting properties can be obtained.

  According to the seventh aspect of the present invention, the ink-implanting roller that rotates in the circumferential length direction and has a convex pattern at the portion where the ink is applied is provided around the plate surface of the plate cylinder having the concave pattern. In the method for producing an intaglio print, the plate surface is wiped off with a wiping roller, and the ink of the convex pattern embedded in the concave pattern is transferred to the substrate by one rotation of the ink deposition roller. The convex pattern is arranged with a predetermined width and a constant pitch in the circumferential direction, and the convex pattern after the second rotation is arranged in the circumferential direction with respect to the convex pattern of the first rotation. By adopting a manufacturing method in which the pattern is shifted by a distance less than one pitch, the convex pattern in the second and subsequent rotations is shifted by one width in the circumferential direction with respect to the convex pattern in the concave pattern in the first rotation. Shift in Since to be made, each rotation, i.e. it is possible to provide intaglio prints having a high variable pattern of anti-counterfeiting properties patterns for each number of printed sheets changed.

  In the invention according to claim 8, the distance from the convex pattern of the second rotation to the convex pattern of the first rotation is less than one pitch of the convex pattern in the circumferential direction. The shift of the division is to reduce the circumference of the ink landing roller by a distance that is less than one pitch of the convex pattern relative to the circumference of the plate cylinder, or to apply the ink to the circumference of the plate cylinder. It is obtained by increasing the peripheral speed of the roller by a distance that is less than one pitch of the convex pattern. By this shifting, the convex pattern in the second and subsequent rotations is different from the convex pattern in the concave pattern in the first rotation. The intaglio printed matter having a variable pattern having a high anti-counterfeit property by changing the pattern for each rotation, that is, for each number of printed sheets, is formed by shifting by a distance less than one pitch in the circumferential direction. To do Can.

  According to the invention according to claim 9 described above, the projection pattern is formed in a plurality of colors, and each of the plurality of colors is shifted from each other by one width of the projection pattern, thereby making each rotation. In addition to the fact that the pattern itself is changed, it is possible to provide an intaglio printed matter having a multicolor variable pattern that changes to a plurality of colors and has higher anti-counterfeiting properties and excellent design.

  Further, according to the invention of claim 10, the manufacturing method of forming the convex pattern of the final color of the plurality of colors with all solids, that is, forming the entire surface with a flat convex pattern. This eliminates the need for a convex pattern arranged at a predetermined width and a constant pitch, making it easier to produce an ink landing roller and further complementing the gap between the convex patterns before the final color. It is possible to obtain an intaglio printed matter having a multicolor variable pattern that is good in appearance.

  Moreover, according to the invention which concerns on the said 11th aspect, the intaglio printed matter which has a variable pattern with a higher anti-counterfeit effect is obtained by setting it as the manufacturing method which uses at least 1 color of the said several colors as special ink. Can do.

  Further, according to the invention according to claim 12, by making the special ink of claim 11 into a fluorescent intaglio ink or an infrared absorbing intaglio ink, it is impossible to visually recognize the black ink or the infrared ray. Since the variable pattern can be visually recognized by using the monitor, it is possible to obtain an intaglio printed matter having a variable pattern with further improved forgery prevention.

  Further, according to the invention of claim 13, by adopting a manufacturing method in which the concave pattern that forms the plate surface of the plate cylinder is a lattice-like or deformed lattice-like design, the plate surface of the plate cylinder has a pattern other than the concave pattern. In other words, the non-image portion is almost eliminated, so that the number of variable patterns by combining with the convex pattern can be increased (nearly innumerable), and thus an intaglio printed matter having a variable pattern with improved anti-counterfeiting can be obtained. Obtainable.

  The best mode for carrying out the present invention will be described below in detail with reference to the drawings.

  In the present invention, for example, the intaglio printed matter (1-1) of the first rotation of the plate cylinder or the ink landing roller as shown in FIG. 2 (a) and the second rotation as shown in FIG. 2 (b). A color ink pattern (A) and B color ink pattern (B) as shown in FIG. 2C and the intaglio printed matter (1-3) at the third rotation as shown in FIG. And an intaglio printed matter having a variable pattern in which the shape and position of the C-color ink pattern (C) are changed one after another, and the anti-counterfeiting property is further improved, and a manufacturing method thereof.

First, in the invention according to the first aspect, for example, as shown in the side view of FIG. 3, the ink landing roller (33) that rotates in the circumferential direction (P) and the portion where ink is applied is a convex pattern. The ink is applied to the plate surface (30a) of the plate cylinder (30) having the concave pattern, and the plate surface (30a) on which the ink is applied is wiped with a wiping roller (34) that rotates in reverse. The ink of the convex pattern embedded in the concave pattern of the plate surface (30a) is transferred to the substrate (10) between the impression cylinder (32) and the plate cylinder (30) by one rotation of the ink deposition roller (33). The intaglio printed matter transferred to the plate surface (30a) having a concave pattern (20) in which vertically long and narrow ▽ and ▽ are connected as shown in FIG. As shown in (b), the convex pattern (21) is in the circumferential direction. FIG. 5A shows, for example, the case where ink is deposited using an ink deposition roller (33) having a predetermined width (W) in P) and arranged at a constant pitch (T). Thus, as shown in FIG. 5 (b), the convex ink pattern (21-2) of the second rotation is the circumference of the convex ink pattern (21-1) of the first rotation of the ink setting roller. It is shifted in the longitudinal direction (P) by one width (W) that is less than the distance of one pitch (T) of the convex ink pattern (21-1). Further, as shown in FIG. 6 (c), the convex ink pattern (21-3) of the third rotation is formed in the circumferential direction (P) with respect to the convex ink pattern (21-2) of the second rotation. Further, it is shifted by one width (W) of the convex ink pattern (21-2).

  In this way, the convex ink pattern (21-1, 21-2, 21-3) formed on the plate surface (30a) is wiped off the ink other than the concave pattern (20) by the wiping roller (34), and is then used as a paper sheet. When transferred to the substrate (10), for example, as shown in FIG. 6 (a), the monochrome image line (22) obtained by the first rotation printing of the ink landing roller is shown in FIG. 6 (b). As shown in FIG. 2, the monochrome image line (22) obtained by the second rotation printing is sent to the substrate (10) by one width (W) of the convex pattern forming the image line (22). Intaglio printed matter (1) having a variable pattern shifted in the direction (Q).

  Further, as shown in FIG. 6 (c), a monochrome image obtained by the third rotation printing, as shown in FIG. 6 (c), with respect to the monochrome image line (22) obtained by the second rotation printing shown in FIG. 6 (b). The line (22) is shifted in the feeding direction (Q) of the substrate (10) by one width (W) which is less than the distance of one pitch (T) of the convex pattern forming the image line (22). Intaglio printed matter (1) having a variable pattern.

  The reason why the image line (22) obtained for each rotation of the ink landing roller (33) is only one width (W) less than the distance of one pitch (T) of the convex pattern is, for example, This is because shifting by one pitch (T) is not preferable because the same pattern is obtained for each rotation.

  The inventions according to claims 2 and 3 are multicolored intaglio prints (1) having variable patterns shown in FIGS. 6 (a), 6 (b) and 6 (c). As shown in the side view of FIG. 1, the A color ink landing roller (33A), which rotates in the circumferential direction (P) and has a convex pattern on the portion where ink is applied, and the B color ink landing roller (33B) The C color ink landing roller (33C) is arranged in order, and each (A, B, C) color ink is applied to the plate surface (30a) of the plate cylinder (30) having the concave pattern. Wipe the plate surface (30a) on which each color ink has been applied with a wiping roller (34) that rotates in reverse, and each ink on the convex pattern that has been applied in the concave pattern on the plate surface (30a). (33A, 33B, 33C) with one rotation of the impression cylinder (32) A intaglio print multicolor (three colors), which is transferred to a substrate (10) between the plate cylinder (30).

  The multicolor (three colors) intaglio printed material is, for example, a plate surface of a plate cylinder (30) in which concave pattern (20) of Δ ▽ as shown in FIG. 7 (a) is arranged in the circumferential direction (P) ( 30a), for example, as shown in FIG. 7B, an A color ink landing roller (21A) having a convex pattern (21A) having a predetermined width (W) and pitch (P) on which the A color ink is deposited ( As shown in FIG. 7 (c), the convex of 33A) and the B color ink shifted in the width direction (P) by one width (W) is applied to the A color ink landing roller (33A). B color ink inking roller (33B) having a part pattern (21B), and C color ink inking, as shown in FIG. Each (A, B, C) color ink is transferred to each color ink landing roller (33A) by the roller (33C). In the first rotation of 33B, 33C), as shown in FIG. 8A, the A color ink pattern (A) and the B color ink shifted by 1 width (W) in the circumferential length direction (P) from the A color ink pattern (A) The pattern (B) and the C color ink pattern (C) are formed on the entire surface.

  The plate surface (30a) shown in FIG. 8 (a) is wiped off with a wiping roller, and only the color ink patterns (A, B) (the C ink pattern (C) is wiped off) are transferred to a substrate such as paper ( When printing, for example, as shown in FIG. 9A, the A ink pattern (A) and the B ink pattern (B) are formed on the base material (10) so as to be shifted from each other by one width (W). This is a multicolor intaglio printed matter (2) having a pattern.

The A color ink pattern (A) and the B color ink pattern (B) are more peripheral than the first rotation A color ink pattern (A) and B color ink pattern (B). It is formed by shifting by one width (W) in the longitudinal direction (P).

  The plate surface (30a) shown in FIG. 8 (b) is wiped off with a wiping roller, and each color ink pattern (A, B) (however, the C ink pattern (C) is wiped off) is removed from the base material such as paper. When transferred (printed), for example, as shown in FIG. 9B, the A ink pattern (A) and the B ink pattern (B) are formed on the base material (10) so as to be shifted from each other by one width (W). A multicolor intaglio printed matter (2) having a variable pattern.

The A color ink pattern (A) and the B color ink pattern (B) Is formed by being shifted by one width (W) in the circumferential direction (P) from the A color ink pattern (A) and the B color ink pattern (B) of the second rotation.

  The plate surface (30a) shown in FIG. 8 (c) is wiped off with a wiping roller, and each color ink pattern (B, C) (however, the A color ink pattern (A) is wiped off) on the base material such as paper only. Is transferred (printed), for example, as shown in FIG. 9C, the B ink pattern (B) and the C ink pattern (C) are shifted from each other by one width (W) on the base material (10). A multicolor intaglio printed matter (2) having a variable pattern formed is used.

  In the inventions according to claim 4 and claim 5, for example, any one of the color ink patterns (A, B, C) shown in FIGS. 9 (a), (b), and (c) is used as fluorescent intaglio ink. Or it is set as the multicolor intaglio printed matter (2) which has the variable pattern formed with the infrared rays absorption intaglio ink.
