Description

[Technical field]

[0001] The present invention relates to printed matter such as banknotes, stock certificates, securities, travel tickets, passports, and cards. [Background technology]

[0002] Measures to prevent counterfeiting and falsification are important for printed materials such as banknotes, stock certificates, securities, travel tickets, passports, and cards.

[0003] As a measure to prevent counterfeiting and tampering, the printed matter is printed using different printing methods, for example offset printing and intaglio printing, to improve resistance to counterfeiting and tampering.

[0006] Printed matters produced using different printing methods have complex patterns in order to improve counterfeit resistance and design. For example, a printed design produced using offset printing may have light and dark shades, and intaglio printing lines may be placed at the borders between the light and dark shades.

[0007] However, if the offset printing and the intaglio printing are misaligned in a printed product having such a configuration, the boundary between the light and dark shades of the offset printing becomes clearly visible, causing an unpleasant feeling.

[0008] To provide a printed matter that does not give the impression of misalignment even when there is misalignment between a first printed pattern produced by a first printing method and a second printed pattern produced by a second printing method that is different from the first printing method. [Means for solving the problem]

[0009] The printed matter of the present invention described in claim 1 has a first printed pattern 10 printed by a first printing method and a second printed pattern 20 printed by a second printing method printed on at least a portion of the surface of a substrate 1, a first printed pattern A pattern 10A and a first printed B pattern 10B having different pattern densities are printed as the first printed pattern 10, and a second printed line 21 is printed on top of the first printed pattern 10 as the second printed pattern 20, characterized in that a blending boundary portion 30 is provided at the boundary between the first printed A pattern 10A and the first printed B pattern 10B, the blending boundary portion having an intermediate pattern density that is lighter in pattern density than the first printed A pattern density of the first printed A pattern and darker in pattern density than the first printed B pattern density of the first printed B pattern, and the second printed line 21 is printed at the blending boundary portion 30.

[0010] The present invention described in claim 2 is characterized in that, in the printed matter described in claim 1, the first printed A line 11A forming the first printed A pattern 10A and the first printed B line 11B forming the first printed B pattern 10B have different line widths, and the boundary line 31 forming the blending boundary portion 30 has a line width narrower than the first printed A line 11A and wider than the first printed B line 11B.

[0011] The present invention described in claim 3 is characterized in that, in the printed matter described in claim 1, the first printed A line pitch 12A forming the first printed A pattern 10A and the first printed B line pitch 12B forming the first printed B pattern 10B are different pitches, and the boundary line pitch 32 forming the blending boundary portion 30 is narrower than the first printed A line pitch 12A and wider than the first printed B line pitch 12B. Effect of the Invention

[0012] According to the printed matter of the present invention, the second printed line printed over the first printed pattern is positioned at the blending boundary, so that even if there is a misalignment between the first printed pattern printed by the first printing method and the second printed pattern printed by the second printing method, the misalignment is not noticeable. [Brief description of the drawings]

[0013] [Figure 1] FIG. 1 is a conceptual diagram showing a printed matter according to an embodiment of the present invention; [Diagram 2] FIG. 1 is a conceptual diagram for explaining a familiarity boundary portion of the present invention; [Diagram 3] 1 is a schematic diagram showing the main part of the familiarity boundary portion according to each embodiment of the present invention; DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] The printed matter according to the first embodiment of the present invention has a blending boundary portion at the boundary between first printed pattern A and first printed pattern B, which have different pattern densities, and the blending boundary portion has an intermediate pattern density in which the pattern density of first printed A pattern is lighter than the first printed A pattern density and the pattern density of first printed B pattern is darker than the first printed B pattern density, and a second printed line is printed at the blending boundary portion.

[0015] According to this first embodiment, the second printed line printed over the first printed pattern is positioned at the blending boundary, so that even if there is a misalignment between the first printed pattern printed by the first printing method and the second printed pattern printed by the second printing method, the misalignment is not noticeable.

[0016] The second embodiment of the present invention is a printed matter in the first embodiment, in which the first printed A line forming the first printed A pattern and the first printed B line forming the first printed B pattern have different line widths, and the boundary line forming the blending boundary portion has a line width narrower than the first printed A line and wider than the first printed B line.

[0017] According to the second embodiment, when the first printed A line and the first printed B line have different line widths, arranging the second printed line at the boundary between the first printed A pattern and the first printed B pattern will result in a noticeable visual misalignment. However, by arranging the second printed line at the blending boundary portion at the boundary between the first printed A line and the first printed B line, the misalignment is not noticeable.

[0018] The third embodiment of the present invention is a printed matter in the first embodiment, in which the first print A line pitch forming the first print A pattern and the first print B line pitch forming the first print B pattern are different pitches, and the boundary line pitch forming the blending boundary portion is narrower than the first print A line pitch and wider than the first print B line pitch.

[0019] According to the third embodiment, when the first printed A line pitch and the first printed B line pitch are different pitches, arranging the second printed line at the boundary between the first printed A pattern and the first printed B pattern will result in a noticeable visual misalignment. However, by arranging the second printed line at the blending boundary portion at the boundary between the first printed A line and the first printed B line, the misalignment is not noticeable. EXAMPLES

[0020] The printed matter according to the present invention will now be described. Fig. 1 is a conceptual diagram showing a printed matter according to one embodiment of the present invention, Fig. 1(a) is a conceptual diagram showing the printed matter of this embodiment, Fig. 1(b) is a conceptual diagram showing a first printed pattern by a first printing method, and Fig. 1(c) is a conceptual diagram showing a second printed pattern by a second printing method.

[0021] The printed matter of this embodiment is, for example, a printed matter such as a banknote, a passport, or an identification card, or a card such as a cash card, and the base material 1 is made of paper or plastic.

[0022] As shown in FIG. 1(a), the printed matter of this embodiment has a first printed pattern 10 printed by a first printing method and a second printed pattern 20 printed by a second printing method printed on at least a part of the surface of a substrate 1.

[0023] Here, the first printing method is offset printing and the second printing method is intaglio printing or screen printing.

[0024] As shown in FIG. 1(b), as the first printed pattern 10, a first printed pattern A 10A and a first printed pattern B 10B are printed.

[0025] A blending boundary portion 30 is provided at the boundary between the first printed A pattern 10A and the first printed B pattern 10B.

[0026] Although only the second printed pattern 20 is shown in Fig. 1(c), the second printed lines 21 forming the second printed pattern 20 are printed superimposed on the first printed pattern 10 shown in Fig. 1(b). The second printed lines 21 printed on the boundary between the first printed A pattern 10A and the first printed B pattern 10B are printed on the blending boundary portion 30.

[0027] According to this embodiment, the matching boundary portion 30 printed by offset printing can make the misregistration of the second printing line 21 printed by intaglio printing or screen printing less noticeable.

[0028] FIG. 2 is a conceptual diagram for explaining the familiarity boundary of the present invention, where FIG. 2(a) is a conceptual diagram having a familiarity boundary formed by the printed matter of this embodiment, FIG. 2(b) is an enlarged view of the familiarity boundary, FIG. 2(c) is an exploded view of the enlarged view of the familiarity boundary, and FIG. 2(d) is a conceptual diagram of a comparative example in which no familiarity boundary is formed.

[0029] 2(a), 2(b), and 2(c), the first print A pattern density of the first print A pattern 10A and the first print B pattern density of the first print B pattern 10B are different pattern densities, and the first print A pattern density is darker than the first print B pattern density. The blending boundary portion 30 has a pattern density lighter than the first print A pattern density and darker than the first print B pattern density.

[0030] The width of the familiar boundary portion 30 is set to be wider than that of the second printed object line 21. The second printed object line 21 is printed on the familiar boundary portion 30.

[0031] In this embodiment, details will be described later, but by changing the line widths of the first printed A pattern 10A, the first printed B pattern 10B, and the blending boundary portion 30, the first printed A pattern density, the first printed B pattern density, and the blending boundary portion 30 are made to have different pattern densities.

[0032] The comparative example shown in Fig. 2(d) shows a state where the second printed line 21 is printed without misalignment at the boundary between the first printed pattern A 10A and the first printed pattern B 10B. As shown in Fig. 2(d), if the first printed pattern 10 by the first printing method and the second printed pattern 20 by the second printing method are aligned, there is no problem, but if there is misalignment, the boundary between the light and dark shades of the first printed pattern A 10A and the first printed pattern B 10B becomes clearly visible.

[0033] As shown in this embodiment, when the first printed A pattern density and the first printed B pattern density are viewed from a specified distance as different pattern densities, if the second printed line 21 is placed at the boundary between the first printed A pattern 10A and the first printed B pattern 10B, the misalignment will be clearly visible. However, by placing the second printed line 21 at the blending boundary portion 30 provided at the boundary between the first printed A pattern 10A and the first printed B pattern 10B, an area is provided that allows for misalignment of the print, and the blending boundary portion 30 is made an intermediate pattern density between the first printed A pattern 10A and the first printed B pattern 10B, the difference in shading is mitigated and the misalignment is not noticeable.

[0034] Furthermore, by making the width of the familiar boundary portion 30 wider than the second printed object line 21, the misalignment of the second printed object line 21 is further prevented from being felt.

[0035] 3 is a conceptual diagram of a main part showing the blending boundary portion 30 of the present invention. As described above, the blending boundary portion 30 has an intermediate pattern density between the first printed A pattern 10A and the first printed B pattern 10B, thereby serving to reduce the difference in shading between the first printed A pattern 10A and the first printed B pattern 10B. Here, a method of making the blending boundary portion 30 an intermediate pattern density between the first printed A pattern 10A and the first printed B pattern 10B will be described.

[0036] In FIG. 3(a), a first printed A object line 11A forming a first printed A pattern 10A and a first printed B object line 11B forming a first printed B pattern 10B have different object line widths.

[0037] 3(a), when the first printed A image line 11A has a wider image width than the first printed B image line 11B, the boundary image line 31 forming the blending boundary portion 30 has an image width narrower than the first printed A image line 11A and wider than the first printed B image line 11B. Note that the pitch of all the images is the same.

[0038] By setting the same pitch but different line widths, the pattern densities of the first printed A pattern 10A, the first printed B pattern 10B and the blending boundary portion are different. Specifically, the line width of the first printed A pattern 11A is the thickest and the line width of the first printed B pattern 11B is the thinnest, and the boundary portion 31 is intermediate between the line widths of the first printed A pattern 11A and the first printed B pattern 11B, so the pattern density of the first printed A pattern is the darkest and the pattern density of the first printed B pattern is the lightest, and the blending boundary portion 30 is an intermediate pattern density between the line density of the first printed A pattern and the line density of the first printed B pattern.

[0039] In FIG. 3(b), a first printed A image line pitch 12A forming a first printed A pattern 10A and a first printed B image line pitch 12B forming a first printed B pattern 10B are different pitches.

[0040] 3(b), when the first print A image line pitch 12A is wider than the first print B image line pitch 12B, the boundary image line pitch 32 forming the blending boundary portion 30 is set to a pitch narrower than the first print A image line pitch 12A and wider than the first print B image line pitch 12B. Note that the image width of all images is the same.

[0041] By setting the same image width but different pitches, the pattern densities of the first printed A pattern 10A, the first printed B pattern 10B and the blending boundary portion are different. Specifically, the pitch of the first printed A image 11A is the widest and the pitch of the first printed B image 11B is the narrowest, and the boundary image 31 is intermediate between the first printed A image 11A and the first printed B image 11B, so the pattern density of the first printed A is the lightest and the pattern density of the first printed B is the darkest, and the blending boundary portion 30 is an intermediate pattern density between the first printed A pattern density and the first printed B pattern density. [Industrial Applicability]

[0042] The present invention is suitable for printing items such as banknotes, stock certificates, securities, travel tickets, passports, and cards, but can also be used for other general printed items. [Explanation of symbols]
