DETAILED DESCRIPTION OF THE INVENTION
An example of an anti-counterfeit printed matter and a method for producing the same according to the present invention will be described with reference to the drawings. In FIG. 1, various lines (a) are offset printed with colored ink different from the surface color of the printed material on the printed material. The various line relief images (b) in which specific characters and figures are given two-dimensionally to the basic lines on the transparent intaglio ink on the top are parallel to the various lines (a), that is, the flow of the various lines. And printed matter 1 (e1) obtained by intaglio printing so that the flow of the basic lines of the various relief images is parallel and overlapped. Therefore, due to the structure of the printed matter 1 (e1), the various line lines (a) offset-printed between the characters and graphic parts (1) and the background part (2) of the various line relief images (b) printed intaglio. ) Is always different.
[0019]
When the printed matter 1 and the printed matter 1 (e1) obtained by the production method thereof are observed from the direction perpendicular to the printed surface, that is, the printed image, the various line relief images (b) themselves printed with the transparent intaglio ink are confirmed. The various lines (a) that are difficult to be offset and do not overlap with the intaglio ink can be confirmed as they are, and the various lines (a) that are offset printed that overlap the intaglio ink are also transparent with the intaglio ink. It can be confirmed because there is. Accordingly, the various lines (a) that have been offset printed can be confirmed.
[0020]
When the printed matter 1 (e1) is observed while changing the observation angle from a direction substantially perpendicular to the image line constituting the printed image, the various line relief images printed intaglio with the transparent intaglio ink are Since it is transparent and raised, the reflection of light and the refractive index affect it, and the appearance of the various lines (a) printed on the surface of the printing medium and the offset printing changes. At this time, since the positional relationship between the various lines (a) offset-printed differs between the characters and graphic parts (1) and the background part (2) of the various line-relief images (b) printed intaglio. As a result, a difference occurs in contrast between the graphic part (1) and the background part (2), so that a specific character or graphic can be confirmed together with a change in contrast depending on the observation angle.
[0021]
An example of the anti-counterfeit printed matter according to the present invention and a method for producing the same will be described with reference to the drawings. In FIG. 2, various characters in which specific characters and figures are given two-dimensionally on a basic line with a transparent intaglio ink on a printing medium. A line relief image (b) is intaglio-printed thereon, and various lines (a) are printed in parallel with the various line relief images (b) with colored ink different from the surface color of the printing material, that is, the various types This is a printed matter 2 (e2) obtained by offset printing so that the flow of the lines and the flow of the basic lines of the various relief images are parallel and overlap. Therefore, due to the structure of the printed matter 2 (e2), the various lines (a) of the various line relief images (b) printed in intaglio are offset printed between the characters and the graphic part (1) and the background part (2). ) Is always different.
[0022]
When the printed matter 2 (e2) obtained by the printed matter and its production method is observed from a direction perpendicular to the printed image, the various line relief images (b) themselves printed with the transparent intaglio ink are difficult to confirm, In addition, the line image (a) that has been offset printed and located on the paper and on the line relief image that has been intaglio printed can be confirmed.
[0023]
When the printed material 2 (e2) is observed while changing the observation angle from a direction substantially orthogonal to the image line constituting the printed image, the various relief images printed on the intaglio with the transparent intaglio ink are Since it is transparent and raised, the reflection of light and the refractive index affect it, and the appearance of the surface of the printing medium and the various lines (a) printed by offset printing changes. At this time, since the positional relationship between the various lines (a) offset-printed differs between the characters and graphic parts (1) and the background part (2) of the various line-relief images (b) printed intaglio. As a result, a difference occurs in contrast between the graphic part (1) and the background part (2), so that a specific character or graphic can be confirmed together with a change in contrast depending on the observation angle.
[0024]
Furthermore, the image used in the forgery-preventing printed matter and the method for producing the same according to the present invention is not limited to the various lines (a) and the various line relief images (b) as described above, but also uses a concentric circle image (c) as an offset printed image. A concentric relief image (d) obtained by two-dimensionally adding information such as specific characters and figures to a basic concentric circle image can be used as an intaglio printing image using transparent intaglio ink.
[0025]
In FIG. 3, the concentric circle image (c) is offset-printed with a colored ink different from the surface color of the printed material on the printed material, and the concentric relief image (d) is printed with the transparent intaglio ink. ) And the printed material 3 (e3) obtained by intaglio printing so that the center overlaps, and in FIG. 4, the concentric relief image (d) is intaglio-printed on the printed material with the transparent intaglio ink, and then the printed material. The printed product 4 (e4) or the printed product 4 is obtained by performing offset printing on the concentric circle image (c) with the color ink different from the surface color of the concentric relief image (d) so as to overlap the center. When the printed surface of (e4), that is, the printed image is observed from the vertical direction, the concentric image (c) printed by offset printing can be confirmed.
[0026]
When the observation angle was changed from a direction substantially orthogonal to the tangent to the image line constituting the printed image of the printed material 3 (e3) or the printed material 4 (e4), intaglio printing was performed with the transparent intaglio ink. Since the concentric relief image is transparent and raised, light reflection and refractive index are affected, and the appearance of the concentric image (c) printed on the surface of the substrate and offset printing is changed. At this time, since the positional relationship between the concentric circle image (c) printed by offset printing differs between the character or graphic portion (1) of the concentric relief image (d) printed in intaglio and the background portion (2), the character or graphic portion There is a difference in contrast between (1) and the background portion (2), and therefore a specific character or figure can be confirmed along with the change in contrast depending on the viewing angle.
[0027]
Furthermore, since the printed matter 3 (e3) and the printed matter 4 (e4) use concentric circular line images, they can be observed by changing the observation angle from any direction in the circumferential direction. The figure can be confirmed together with the change in contrast depending on the observation angle.

【Example】
Embodiments of the present invention will be described below with reference to the drawings.
(Example 1)
In FIG. 1, various lines (a) are offset-printed with colored ink different from the surface color of the paper on the paper to be printed, and “P” is printed on the basic lines with transparent intaglio ink thereon. Various line relief images (b) given information in two dimensions are parallel to the various line (a) printed by offset printing, that is, the flow of the various lines and the flow of the basic line of the various relief images. Intaglio printing is performed in parallel and overlapping. The printed matter 1 (e1) obtained was structurally intaglio-printed on the various line-relief images (b) with the letter “P” and the graphic portion (1) and the background portion (2) offset printed. The positional relationship with various lines (a) is always different.
[0029]
When the printed matter 1 (e1) is observed from a direction perpendicular to the printed image, the various line relief images (b) themselves are difficult to confirm because the intaglio printing is performed with the transparent intaglio ink, and the transparent intaglio ink The various line (a) portions that have been offset printed that do not overlap can be confirmed as they are, and the various line (a) portions that have been offset printed and that have been overprinted with the transparent intaglio ink have also been intaglio printed. Can be confirmed because it is transparent, and therefore, the various lines (a) printed by offset printing can be confirmed.
[0030]
When the printed matter 1 (e1) is observed by changing the observation angle from a direction substantially orthogonal to the image line constituting the printed image, the various relief images printed intaglio with the transparent intaglio ink are transparent. Since the projection is raised, the reflection of light and the refractive index affect the appearance of the various lines (a) printed on the surface of the paper and offset printed. At this time, the positional relationship between the various lines (a) offset-printed between the letter “P” and the graphic part (1) and the background part (2) of the various line relief images (b) printed intaglio. Therefore, there is a difference in contrast between the letter “P” and the graphic part (1) and the background part (2). Therefore, “P” can be confirmed together with the change in contrast depending on the observation angle. Further, since the various line relief images (b) are intaglio-printed, they have finger sensitivity due to the intaglio ink.
[0031]
(Example 2)
In FIG. 2, various line relief images (b) in which information of “P” is two-dimensionally applied to a basic line with a transparent intaglio ink on a sheet to be printed are intaglio-printed, and the above-described intaglio printing is performed thereon Various lines (a) are intaglio-printed with colored inks different from the surface color of the paper in parallel with the various line relief images (b), that is, the flow of the various lines and the basic lines of the various relief images. The offset printing is performed so that the flows are parallel and overlap. The printed matter 2 (e2) obtained was structurally intaglio-printed on the various line-relief images (b) with the letter “P” and the graphic portion (1) and the background portion (2) offset printed. The positional relationship with various lines (a) is always different.
[0032]
When the printed matter 2 (e2) is observed from a direction perpendicular to the printed image, the various line relief images (b) themselves are intaglio-printed with transparent intaglio ink, and are difficult to confirm, and are printed on the paper and intaglio-printed. Furthermore, the various line (a) itself that has been offset printed and positioned on the various line relief images can be confirmed as it is.
[0033]
When the printed matter 2 (e2) is observed by changing the observation angle from a direction substantially orthogonal to the image line constituting the printed image, the various relief images printed intaglio with the transparent intaglio ink are transparent. Since the projection is raised, the reflection of light and the refractive index affect the appearance of the various lines (a) printed on the surface of the paper and offset. At this time, the positional relationship between the various lines (a) offset-printed between the letter “P” and the graphic part (1) and the background part (2) of the various line relief images (b) printed intaglio. Therefore, there is a difference in contrast between the letter “P” and the graphic part (1) and the background part (2). Therefore, “P” can be confirmed together with the change in contrast depending on the observation angle. Further, since the various line relief images (b) are intaglio-printed, they have finger sensitivity due to the intaglio ink.
[0034]
(Example 3)
In FIG. 3, the concentric circle image (c) is offset-printed on the paper to be printed with a colored ink different from the surface color of the paper, and information “A” is added to the basic concentric circle image with the transparent intaglio ink thereon. The concentric relief image (d) given two-dimensionally is subjected to intaglio printing so that the center of the concentric circle image (c) printed by offset printing overlaps. The printed product 3 (e3) obtained is structurally intaglio printed on the concentric relief image (d) with the letter “A” and the concentric circle image offset (1) and the background portion (2). The positional relationship with (c) is always different.
[0035]
When the printed matter 3 (e3) is observed from the direction perpendicular to the printed image, the concentric relief image (d) itself printed in intaglio is difficult to confirm because it is intaglio printed with the transparent intaglio ink, and the transparent intaglio The concentric relief image (d) on which the offset concentric image on which the ink is not overlapped can be confirmed as it is, and the concentric image (c) on which the transparent intaglio ink is overlapped is also intaglio printed. It can be confirmed because it is transparent, and therefore the concentric image (c) printed by offset printing can be confirmed.
[0036]
When the printed matter 3 (e3) is observed by changing the observation angle from a direction substantially orthogonal to the tangent to the image line constituting the printed image, the concentric relief image intaglio-printed with the transparent intaglio ink is transparent. Since it is raised, the reflection of light and the refractive index affect it, and the appearance of the concentric image (c) printed on the surface of the paper and offset is changed. At this time, the positional relationship between the concentric circle image (c) printed by offset printing is different between the letter “A” and the graphic portion (1) of the concentric relief image (d) printed intaglio and the background portion (2). The contrast between the letter “A” and the graphic part (1) and the background part (2) will be different, so that “A” can be confirmed together with the change in contrast depending on the observation angle. Furthermore, since the printed material 3 (e3) uses a concentric circular line image, it can be observed by changing the observation angle from any direction in the circumferential direction, and “A” is confirmed together with the change in contrast due to the observation angle. can do. Further, since the concentric relief image (d) is intaglio-printed, it has finger sensitivity due to the intaglio ink.
[0037]
(Example 4)
In FIG. 4, a concentric relief image (d) in which information “A” is given two-dimensionally is printed on a concentric circle image which is a basic with a transparent intaglio ink on a paper to be printed, and the surface of the paper is printed thereon. The concentric circle image (c) is offset-printed with the colored ink different from the color so that the center thereof overlaps with the concentric relief image printed on the intaglio. The printed product 4 (e4) obtained is structurally indented and printed on the concentric circle relief image (d) with the letter “A” or the graphic portion (1) and the background portion (2) offset printed. The positional relationship with (c) is always different.
[0038]
When the printed matter 4 (e4) is observed from the direction perpendicular to the printed image, the concentric relief image (d) itself printed on the intaglio is difficult to confirm because it is intaglio printed with the transparent intaglio ink, and on the paper. In addition, the concentric circle image (c) that has been offset printed and positioned on the concentric relief image (d) that has been subjected to intaglio printing can be confirmed.
[0039]
When the printed matter 4 (e4) is observed by changing the observation angle from a direction substantially perpendicular to the tangent to the image line constituting the printed image, the concentric relief image printed intaglio with the transparent intaglio ink is transparent. Since it is raised, the reflection of light and the refractive index affect it, and the appearance of the concentric image (c) printed on the surface of the paper and offset is changed. At this time, the positional relationship between the concentric circle image (c) printed by offset printing is different between the letter “A” and the graphic portion (1) of the concentric relief image (d) printed intaglio and the background portion (2). The contrast between the letter “A” and the graphic part (1) and the background part (2) will be different, so that “A” can be confirmed together with the change in contrast depending on the observation angle. Furthermore, since the printed material 4 (e4) uses a concentric circular line image, it can be observed by changing the observation angle from any direction in the circumferential direction, and “A” is confirmed together with the change in contrast due to the observation angle. can do. Further, since the concentric relief image (d) is intaglio-printed, it has finger sensitivity due to the intaglio ink.
[0040]
In this embodiment, a commonly used paper is used as the printing medium. However, in the present invention, the printing medium is not limited to the paper, and any printing material such as film, plastic, or intaglio printing may be used. Further, the characters and figures that can be confirmed are not limited to “P” or “A”.

【The invention's effect】
As described above, the printed matter produced by the method for producing a forgery-preventing printed matter according to the present invention includes various lines by offset printing with colored ink different from the surface color of the substrate, and various intaglio printing with transparent intaglio ink. It is a forgery-preventing printed matter that is overprinted so as to overlap in parallel without overlapping the printing order of the line relief image, and a concentric circle image by offset printing with colored ink different from the surface color of the substrate, and It is a forgery-preventing printed matter obtained by overprinting the concentric relief images obtained by intaglio printing with the transparent intaglio ink so that the centers overlap without questioning the order of printing.
[0042]
When the printed material is observed from the vertical direction, the various lines or the concentric images can be confirmed, and the printed material is substantially orthogonal to the image lines constituting the various printed lines that are offset printed, or concentric images that are offset printed. When the observation angle is changed from a direction substantially orthogonal to the tangential direction with respect to the image line constituting the image, the various line relief images or the concentric relief images intaglio-printed with the transparent intaglio ink are transparent and raised. Therefore, the reflection of light and the refractive index affect the appearance of the surface of the printing medium and the various lines or the concentric images printed by offset printing. At this time, since the positional relationship between the various lines printed with offset printing differs between the characters and graphic parts of the various line relief images printed on intaglio and the background parts, there is a difference in contrast between the characters and graphic parts and the background part. It is possible to confirm specific characters and figures that appear and appear with a change in contrast depending on the viewing angle. Further, since the anti-counterfeit printed matter uses intaglio printing, it is possible to obtain unique finger sensibility due to the printing of the intaglio ink.
[0043]
These effects can be easily confirmed by ordinary people without using any device, etc., and since the ink pile due to intaglio printing is not reproduced on a copy by a color copier or the like, the contrast due to a change in observation angle is not reproduced. Characters and figures with changes are not confirmed, and finger sensitivity by intaglio printing is lost. Therefore, whether or not the printed matter is forged or altered by a copying machine or the like by performing anti-counterfeit printing according to the present invention can be genuinely easily and surely used without using an instrument or device. Or a copy.
