JP7141661B2 - Variable information printed matter and its creation method - Google Patents

Description

The present invention relates to a variable information printed matter and a method for producing the same.

Background patterns are printed, and printed materials are used on which, for example, personal information and the like are printed as variable information that varies from printed material to printed material. Such variable information printed materials include, for example, various certificates such as passports, driver's licenses, resident cards, family register copies, cash vouchers such as gift certificates and securities, credit cards, and the like.

Conventionally, such variable information printed matter is printed with a background pattern such as a tint block pattern on a base material, and a commonly used certificate mount (hereinafter referred to as "blank printed matter") is created and stored. Fixed information such as ruled lines and variable information such as personal information are printed on the surface by additional printing.

However, such a variable information printed matter is provided with an anti-counterfeiting function by means of a background pattern. Therefore, by stealing stored blank printed matter and printing variable information on the surface of the blank printed matter, it is possible to easily forge the printed matter. Furthermore, it is difficult to store and manage the blank printed matter so that it will not be stolen, resulting in an increase in cost.

Also, after forming a background pattern as a first printed layer on the surface of a base material, fixed information and variable information are formed as a second printed layer on the surface. Therefore, it is relatively easy to forge by removing the variable information contained in the second printed layer, leaving the background pattern of the first layer, and printing other variable information.

A conventional certificate printing method is disclosed in, for example, Japanese Patent Application Laid-Open No. 2000-037976.

This patent document 1 describes a printing medium in which a color-variable printing layer whose color changes depending on the angle is provided on a part of a base material, and variable information is printed in that area. In this print medium, a color variable print layer is formed on an authenticity discriminating area, which is a partial area of the medium base material, and variable information is included in this color variable print layer.

Japanese Patent Application Laid-Open No. 2002-274000

However, even in the printing medium described in Patent Document 1, the anti-counterfeiting effect for variable information depends only on the color-variable printing layer, and the anti-counterfeiting effect cannot be obtained in areas where the color-variable printing layer is not formed. There was a problem that it could not be done and it was not sufficient as a countermeasure.

A variable information printed matter and a method for creating the same according to an embodiment of the present invention will be described below with reference to the drawings.

First, the configuration of a variable information printed matter as a comparative example will be described.

As shown in FIG. 1A, on the surface of a base material 101, each printed material includes a background pattern 102, fixed information 103 such as ruled lines having fixed contents common to each printed material, and personal information. For example, variable information 104a such as an identification card number and variable information 104b such as a personal name are formed by printing as information having different contents for each.

As a variable information printed matter according to such a comparative example, as shown in FIG. 1B, a blank printed matter in which a background pattern 102 is formed in advance on the surface of a substrate 101 is prepared and stored.

Then, the fixed information 103 and the variable information 104a and 104b as shown in FIG. 1(c) are printed on the surface of the blank printed material by so-called overprinting to obtain the variable information as shown in FIG. 1(a). A print is created.

A procedure for forging a variable information printed matter according to such a comparative example will be described with reference to FIG.

First, as shown in FIG. 2(a), after the background pattern 102 is formed on the surface of the substrate 101, if there is a genuine variable information printed matter in which the fixed information 103 and the variable information 104a and 104b are formed, Assume.

For such variable information printed matter, only the variable information 104a and 104b are erased as shown in FIG. c) is printed as shown.

Such a forgery procedure will be described in more detail with reference to FIG. As shown in FIG. 3A, a background pattern 102 is formed on the surface of a substrate 101 as a first printed layer. Thereafter, fixed information 103 and variable information 104a are printed as the second printed layer on the surface of the base material 101 on which the background pattern 102 is formed as the first printed layer.

As shown in FIG. 3B, the background pattern 102 as the first printed layer and the fixed information 103 as the second printed layer remain, and the variable Only information 104a is removed.

As shown in FIG. 3C, the second layer is printed on the surface of the base material 101 on which the background pattern 102 as the first printed layer and the fixed information 103 as the second printed layer are left. is forged by forming non-authentic variable information 204a as the printed layer of the

(Embodiment 1)
Thus, in the variable information printed matter according to the comparative example, the background pattern 102 is printed in advance as the first printed layer, and then the variable information 104a is printed as the second printed layer. It was possible to easily forge by removing only the variable information 104a as a layer and printing the inauthentic variable information 204a on its surface as a second printed layer.

On the other hand, the variable information printed matter according to Embodiment 1 of the present invention is printed on the surface of the substrate 1 on which nothing is printed as shown in FIG. All the information including the background pattern 2, the fixed information 3, the variable information 4a and 4b, and the variable information 2-4a and 2-4b included in the background pattern 2 are printed in the same process as shown in FIG. ) is produced.

The background pattern 2 is formed on at least a partial region of the surface of the base material 1, and the variable information 2-4a and 2-4b overlaps the background pattern 2 and is continuously formed with a plurality of the same contents. It is More specifically, according to the first embodiment of the present invention, they are arranged continuously along the drawing lines included in the background pattern 2 according to the regularity of the background pattern 2, for example. The variable information 4a and 4b are formed overlapping the background pattern 2 or not overlapping. In more detail, in Embodiment 1 of the present invention, they are arranged regardless of the regularity of the background pattern 2 and so as not to be visually recognized as part of the background pattern 2 . The variable information 2-4a, 2-4b includes at least part of the contents of the variable information 4a, 4b. The variable information 2-4a and 2-4b have the same color as at least one color included in the background pattern 2, and the variable information 4a and 4b have a color different from the background pattern 2. FIG.

Consider a case where an attempt is made to forge the variable information printed matter according to the first embodiment of the present invention.

First, as shown in FIG. 5A, an attempt is made to forge a variable information printed matter on which a background pattern 2, fixed information 3, variable information 4a and 4b, and variable information 2-4a and 2-4b are formed. In this case, the forger leaves the background pattern 2 and the fixed information 3 as shown in FIG. 5(b) and tries to remove the genuine variable information 4a and 4b. Alternatively, as shown in FIG. 5(c), the background pattern 2 is left and the genuine variable information 4a, 4b and the fixed information 3 are removed.

However, the background pattern 2 formed on the variable information printed material according to the first embodiment of the present invention includes variable information 2-4a and 2-4b as shown in FIG. 5(c). .

Therefore, in the case of forgery, all of the variable information 2-4a such as the ID card number and the variable information 2-4b such as the personal name contained in the background pattern 2 are removed, and the variable information to be forged is removed. must be changed to

As a result, the counterfeiter finds that the counterfeiting is difficult and discourages counterfeiting, resulting in a high anti-counterfeiting effect.

More specifically, as shown in FIG. 6A, the background pattern 2 in the variable information printed matter according to the first embodiment of the present invention includes, for example, an identification card along the lines included in the tint block pattern or the like. Variable information 2-4a such as document number and variable information 2-4b such as personal name are arranged. Therefore, it becomes necessary to replace the variable information 2-4a and 2-4b arranged along the drawing lines of the background pattern 2 with other non-genuine variable information, which makes counterfeiting more difficult.

In addition, since blank printed matter is not used unlike the prior art, there is no need for management to prevent theft, and management costs can be reduced.

A procedure for forging an authentic variable information printed matter according to Embodiment 1 of the present invention will be described with reference to FIG. As shown in FIG. 7A, a background pattern 2, fixed information 3, and variable information 4a are simultaneously printed on the surface of the substrate 1 as the first printed layer.

In this state, the forger attempts to remove the variable information 4a while leaving the background pattern 2 and the fixed information 3 as shown in FIG. 7(b). However, in Embodiment 1 of the present invention, the background pattern 2, the fixed information 3, and the variable information 4a are formed as the same first printed layer. Therefore, it is difficult to leave the background pattern 2 and the fixed information 3 and remove only the variable information 4a. In particular, in a portion where the variable information 4a and the background pattern 2 are in contact with each other, as indicated by the area 5, ink may remain when only the variable information 4a is removed. Further, in the variable information printed material according to Embodiment 1 of the present invention, as described above, the variable information 2-4a and 2-4b are arranged along the background pattern 2 as the same first printed layer, It is extremely difficult to remove not only the variable information 4a but also the variable information 2-4a and 2-4b and rewrite them with other variable information while the background pattern 2 remains. Therefore, according to the variable information printed matter according to Embodiment 1 of the present invention, a high anti-counterfeiting effect can be obtained.

(Embodiment 2)
A variable information printed matter according to Embodiment 2 of the present invention will be described with reference to FIG.

The variable information printed matter according to Embodiment 2 of the present invention is printed with a background pattern as shown in FIG. 2. All information including fixed information 3, variable information 4a and 4b, and variable information 2-4a are printed in the same process to create a variable information printed matter as shown in FIG. 8(a). The variable information 2-4a does not follow the regularity of the background pattern 2 here. More specifically, the variable information 2 - 4 a is not arranged along the drawing lines included in the background pattern 2 . However, the variable information 2-4a is arranged continuously in a fixed direction so that it can be visually recognized as part of the background pattern 2. FIG. The variable information 4 a and 4 b are arranged so as not to be visually recognized as a part of the background pattern 2 irrespective of the regularity of the background pattern 2 .

A case where an attempt is made to forge a variable information printed matter according to the second embodiment of the present invention having such a configuration will be considered.

First, as shown in FIG. 9(a), when attempting to forge a variable information printed matter in which background pattern 2, fixed information 3, variable information 4a and 4b, and variable information 2-4a are formed, The forger tries to remove the variable information 4a and 4b while leaving the background pattern 2 and the fixed information 3 as shown in FIG. 9(b). Alternatively, as shown in FIG. 9C, the background pattern 2 is left and the variable information 4a, 4b and the fixed information 3 are removed.

However, in the background pattern 2 formed on the variable information printed material according to the second embodiment of the present invention, as shown enlarged in FIG. Variable information 2-4a is included.

Therefore, in the case of forgery, not only the variable information 4a and 4b but also the variable information 2-4a, such as the ID card number, contained in the background pattern 2, are included in the variable information to be forged. must change.

As a result, the counterfeiter finds that counterfeiting is difficult and discourages counterfeiting, thereby preventing counterfeiting.

In the variable information printed matter according to the first embodiment of the present invention, the variable information 2-4a and 2-4b included in the background pattern 2 are arranged so as to blend in with the curved lines of the tint block pattern included in the background pattern 2 and having design properties. , and there is a possibility that the forger may be unaware of the existence of the variable information 2-4a, 2-4b.

Therefore, if the variable information 2-4a, 2-4b included in the background pattern 2 is not noticed and the variable information 4a, 4b is replaced and forged, the variable information 2-4a, 2-4b, which is the same as the genuine variable information printed matter, will be printed. 2-4b remains, and a clear difference occurs between the forged variable information 4a and 4b, making it possible to easily determine authenticity.

On the other hand, in the variable information printed matter according to Embodiment 2 of the present invention, the variable information 2-4a included in the background pattern 2 is not arranged along the curved lines included in the tint block pattern of the background pattern 2, It is formed with an intentionally independent existence that does not fit in with the curved lines. As a result, the forger can easily notice the existence of the variable information 2-4a, and his motivation to forge will be discouraged, resulting in a high forgery prevention effect.

(Embodiment 3)
The variable information printed matter according to Embodiment 3 of the present invention is printed with a background pattern as shown in FIG. All information including 2A and 2B, fixed information 3, variable information 4a and 4b, and variable information 2-4a and 2-4b included in the background pattern 2 are printed and formed in the same process, as shown in FIG. A variable information print as shown in a) is produced. Here, in the variable information printed matter according to Embodiment 3 of the present invention, background patterns 2A and 2B different from each other are formed as background patterns.

Also, the variable information 2-4a is arranged continuously along the drawing line according to the regularity of the background pattern 2A, and the variable information 2-4b does not follow the regularity of the background pattern 2B, but They are arranged continuously in a certain direction so as to be visually recognized as part of the pattern 2B. The variable information 4a and 4b are arranged so as not to be visually recognized as part of the background patterns 2A and 2B regardless of the regularity of the background patterns 2A and 2B.

Consider a case where an attempt is made to forge variable information printed matter according to the third embodiment of the present invention.

When attempting to forge a variable information printed matter formed with background pattern 2, fixed information 3, variable information 4a and 4b, and variable information 2-4a and 2-4b shown in FIG. 12(a), The forger will try to remove only the variable information 4a, 4b and leave the other information.

However, the background pattern 2 formed on the variable information printed material according to the third embodiment of the present invention includes variable information 2-4a and 2-4b, as shown enlarged in FIG. is Furthermore, as described above, two different types of background patterns 2A and 2B are formed as background patterns, and variable information 2-4a and 2-4b are formed respectively.

Therefore, in the case of forgery, the variable information to be forged includes not only the variable information 4a and 4b but also the variable information 2-4a and 2-4b included in the two types of background patterns 2A and 2B, respectively. must be changed accordingly. As a result, the counterfeiter discovers that counterfeiting is extremely difficult and loses the motivation to counterfeit, resulting in a high anti-counterfeiting effect.

Furthermore, in the variable information printed matter according to the third embodiment of the present invention, the variable information 2-4a included in the background pattern 2A is arranged along the curving lines of the background pattern 2A included in the background pattern 2A and having design properties so as to fit in. It is However, the variable information 2-4b included in the background pattern 2B is not arranged along the curving line of the background pattern included in the background pattern 2B and has a design property, and is intentionally independent without fitting in. formed. In this way, the variable information 2-4a and 2-4b formed in different manners are present in the different background patterns 2A and 2B, respectively, and it is possible to discourage counterfeiting more effectively.

Further, as shown in FIG. 12(a), the variable information printed material according to the third embodiment of the present invention includes a background pattern 2 and variable information 2-4a and 2-4b. There are empty areas 6a and 6b where 4a and 4b are not formed. Due to the presence of these empty areas 6a and 6b, it is clearly visible that the variable information 2-4a and 2-4b are arranged in the background patterns 2A and 2B, respectively. This can clearly discourage counterfeiting.

(Embodiment 4)
A variable information printed matter according to Embodiment 4 of the present invention will be described with reference to FIG.

A variable information printed matter according to Embodiment 4 of the present invention has a specific product configuration such as a passport, and as shown in FIG. Fixed information 3 and variable information 4a, 4b, and 4c are printed in the same process in areas other than empty areas 6a, 6b, and 6c. For example, the variable information 4a represents an identification card number, etc., the variable information 4b represents a personal name, etc., and the variable information 4c represents a photograph of the face. A boundary portion 7 exists between the variable information 4 c and the background pattern 2 . Variable information 2-4a is formed on the outer periphery of the boundary portion 7. FIG.

Here, the variable information 2-4a is arranged along the boundary portion 7, although it does not follow the regularity of the background pattern 2. FIG. The variable information 2-4b is continuously arranged along the drawing line according to the regularity of the background pattern 2. FIG. Regardless of the regularity of the background pattern 2, the variable information 4a and 4b are arranged so as not to be visually recognized as part of the background pattern.

This boundary portion 7 is provided between the ellipse of the variable information 4c and the background pattern 2, and the boundary portion 7 is blurred. Since such blurring exists between the variable information 4c and the background pattern 2, the boundary line between the variable information 4c and the background pattern 2 or the boundary line between the variable information 4a and the background pattern 2 becomes unclear. . This makes it difficult to cut the variable information 4c into an elliptical shape and change it to another face photograph.

Also, the variable information 2-4a and 2-4b are arranged along the curved image lines included in the background pattern 2, as shown in FIG. 13(b).

With such a configuration, the variable information printed matter according to the fourth embodiment of the present invention can more effectively prevent forgery.

(Embodiment 5)
A configuration of a variable information printed matter according to Embodiment 5 of the present invention will be described with reference to FIGS. 14 and 15. FIG. FIG. 14(a) shows an example of contact points between the background pattern and the variable information in the variable information printed matter according to Embodiment 5 of the present invention, and FIG. 14(b) shows the contact points A partially. is shown magnified in . In this example, the contact point A is formed so that the background pattern 2 and the variable information 4a are connected. Here, the variable information 2-4a does not follow the regularity of the background pattern 2, but is continuously arranged so as to be visually recognized as part of the background pattern 2. FIG.

FIG. 15(a) shows another example of the contact between the background pattern and the variable information in the variable information printed matter according to the fifth embodiment of the present invention, and FIG. 15(b) shows the contact B. It is shown partially enlarged. In this example, a gap exists between the background pattern 2 and the variable information 4a so that they are separated.

The configuration in which the background pattern 2 and the variable information 4a are connected shown in FIG. 14 and the configuration in which the background pattern 2 and the variable information 4a are separated shown in FIG. differ. In the configuration shown in FIG. 15, the presence of the gap at the contact point B allows the variable information 4a to be differentiated from the background pattern 2, thereby improving the visibility.

Further, when there is a gap between the background pattern 2 and the variable information 4a, only the area where the variable information 4a such as "3" exists is erased, and other areas such as "4" and "5" are erased. When trying to change to characters, the relative positional relationship between the changed characters and the background pattern 2 changes, and it becomes necessary to extend or erase a part of the background pattern 2. - 特許庁Thus, it is very difficult to change to another character while maintaining the original gap spacing. Therefore, by providing a gap between the background pattern 2 and the variable information 4a as shown in FIG. 15, a higher forgery prevention effect can be obtained. The gap may be formed entirely between the background pattern 2 and the variable information 4a, or may be formed in at least one of them. If the gap exists only in a limited portion between the background pattern 2 and the variable information 4a, it is difficult for the counterfeiter to notice the existence of the gap, making counterfeiting difficult.

(Embodiment 6)
A variable information printed matter according to Embodiment 6 of the present invention will be described with reference to FIGS. 16 and 17. FIG. A variable information printed matter according to Embodiment 6 of the present invention has a configuration as a specific product form such as a certificate of a local government, for example. The variable information printed matter shown in FIGS. 16 and 17 has the same structure, FIG. 16 shows the visible state when irradiated with ultraviolet rays, and FIG. 17 shows the visible state when photographed by an IR camera using infrared rays. .

As shown in FIGS. 16(a) and 17(a), an infrared absorbing material, for example, is used as an example of an anti-counterfeiting technology in an empty region on the surface of the base material 1 where the variable information 4a and 4b are not formed in advance. A municipality mark 9 is formed with a certain silver ink, and it overlaps the municipality mark 9 with a functional material such as a colorless fluorescent ink that emits light when irradiated with ultraviolet rays, although it is not visible to the naked eye under normal light irradiation. A character "certificate" is formed as shown above, and a municipality mark 10 is formed with a functional material such as colorless fluorescent ink in the center area where variable information is formed.

On the surface of such a base material 1, a background pattern 2 and within the background pattern 2 are formed as shown in FIGS. Variable information 2-4a and 2-4b, fixed information 3, and variable information 4a and 4b, which are formed so as to be familiar, are printed in the same process. The variable information 4a, 4b is made of a material containing, for example, carbon black as an infrared absorbing material.

When the surface of this variable information printed matter is irradiated with ultraviolet rays using the ultraviolet irradiation tool 11, as shown in FIG. Authenticity can be determined by emitting light from the municipality mark 10 . The other background pattern 2, variable information 2-4a, 2-4b, fixed information 3, and variable information 4a, 4b are printed with ordinary ink different from functional materials such as colorless fluorescent ink, and are printed with ultraviolet rays. It does not emit light even if it is irradiated with Further, since the municipality mark 9 is also formed with silver ink, it does not emit light when exposed to ultraviolet rays.

On the other hand, when the IR camera 12 is used to irradiate and photograph the surface of this variable information printed matter with infrared rays, variable information 4a and 4b formed of an infrared absorbing material and local governments are photographed as shown in FIG. 17(c). The mark 9 is visually recognized black.

According to Embodiment 6 of the present invention, in which the present invention is applied to such a certificate of a municipality, not only is the forgery prevention effect of the municipality's marks 9 and 10 formed so as to be included in the background pattern 2 By forming the variable information 2-4a and 2-4b, a high forgery prevention effect can be obtained.

In the variable information printed matter according to the first to sixth embodiments of the present invention, the variable information formed in the background pattern 2 may or may not be legible.

FIG. 18 shows an example in which the variable information has no legibility or readability. As shown in FIG. 18(a), when the variable information 2-4a and 2-4b formed on the surface of the base material 1 is observed with the naked eye 13 under normal light irradiation from the light source 14, , and as shown in a partially enlarged view in FIG. 18(b), the variable information 2-4a and 2-4b are formed in a size that makes it difficult to visually recognize them.

The Arabic numerals shown in FIG. 29(c) are arranged along the image line in which the direction of the straight line changes slightly like a polygonal line, so that the variable information can blend in with the background pattern. The Arabic numerals shown in FIG. 29(d) blend the variable information with the background pattern by arranging them along the image line in which the direction of the straight line changes more greatly than in FIG. 29(c). be able to.

Also, the Arabic numerals shown in FIG. 29(f) are arranged along the drawing lines arranged concentrically as shown in FIG. can let

Also, the Arabic numerals shown in FIG. 29(h) are arranged along the streaks arranged in concentric circles having corrugated irregularities as shown in FIG. Information can be blended into the background pattern.

By using such a technique, the variable information can be blended with the drawing lines included in the background pattern. However, the method of blending the variable information with the background pattern is not limited to that shown in FIG.

The background pattern in the variable information printed matter according to the first to sixth embodiments of the present invention includes various patterns such as a tint block pattern composed of streaks and a tint block pattern composed of halftone dots. The tint block pattern is a pattern such as light-colored halftone dots, sand grains, line drawings, etc., printed on the background of characters and patterns, and includes a continuous tone pattern in which the gradation changes continuously. When the background pattern is a continuous gradation pattern, the first variable information is formed with a density corresponding to the change in gradation of the background pattern. FIG. 30 shows an example of background patterns in variable information printed matter according to the first to sixth embodiments of the present invention.

The background pattern shown in FIG. 30(a) is an example of a line drawing pattern, and is based on a flat tone in which the same pattern is continuously repeated, and the gradation is constant and does not change. However, a pattern in which the gradation is continuously changed may be used.

The background pattern shown in FIG. 30(b) is an example of a continuous gradation pattern, in which the area ratio of halftone dots changes continuously and the gradation changes continuously. The shapes of halftone dots included in such a continuous tone pattern include linear shapes such as triangles, quadrilaterals, and polygons having a pentagon or more, and curved shapes such as circles and ellipses.

The background pattern shown in FIG. 30(c) is an example of a continuous tone pattern like the background pattern shown in FIG. 30(b). is continuously changing. The shape of halftone dots included in this continuous tone pattern has a curved shape such as a circle or an ellipse.

The background pattern shown in FIG. 30(d) is an example of a grainy halftone dot pattern, and the gradation is expressed by the density density of irregularly arranged minute dots. Frequency Modulation) screen. Another halftone dot pattern is called an AM screen (Amplitude Modulation), which expresses gradation with the density of minute dots that are regularly arranged.

The background pattern may be formed on at least a portion of the surface of the substrate, and may be formed on a plurality of regions or may be formed on the entire surface.

Accurate matching of prints is difficult when different plates are used for each color, but Zummel printing is used, which enables accurate matching of fine lines by applying multicolor inks on one plate. wavy patterns may be formed.
