Description

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

A printed matter in which a background pattern is printed and personal information or the like is printed on the surface of the printed matter is used as variable information that differs for each printed matter. Such variable information printed matter includes, for example, various certificates such as passports, driver's licenses, resident's cards, and family register copies, gift certificates, cash vouchers such as securities, credit cards, and the like.

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

However, such a variable information printed matter is provided with an anti-counterfeiting function by a background pattern. Therefore, since the stored blank printed matter can be easily forged by stealing and printing variable information on the surface thereof, a sufficient anti-counterfeiting effect has not been obtained. Furthermore, it is difficult to store and manage the blank printed matter so that it will not be stolen, which has led to an increase in cost.

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

As a conventional method for printing a certificate, for example, there is one described in JP-A-2000-0377976.

This Patent Document 1 describes a printing medium in which a color variable printing layer whose color changes depending on an angle is provided on a part of a base material, and variable information is printed in the region. In this print medium, a color variable printing layer is formed on a genuine product discrimination region, which is a part of a medium base material, and the color variable printing layer contains variable information.

JP-A-2002-274000

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

In view of the above circumstances, an object of the present invention is to provide a variable information printed matter and a method for producing the same, which can more effectively prevent forgery of the variable information printed matter while reducing the cost.

In the variable information printed matter of the present invention, a background pattern formed in at least a part of the surface of the base material and a plurality of first variable ones in which the same contents are continuously formed overlapping the background pattern. It is characterized by including information and a second variable information formed so as to overlap or not overlap with the background pattern.

The first variable information is continuously formed according to the regularity of the background pattern, or is continuously formed so as to be visually recognized as a part of the background pattern, and the second variable information is the regularity of the background pattern. Is irrelevant and may be formed so as not to be visually recognized as a part of the background pattern.

The first variable information may be continuously arranged along the image lines or halftone dots included in the background pattern.

As the first variable information, the first variable information may be formed with a density corresponding to a change in the gradation of the background pattern.

The first variable information may include at least a part of the content of the second variable information.

The first variable information may have the same color as at least one color included in the background pattern, and the second variable information may have a color different from that of the background pattern.

The background pattern may include at least one of a tint block pattern composed of image lines, halftone dots, or grain, or a continuous gradation pattern in which the gradation changes continuously.

The first variable information may be formed in a size readable by the naked eye in a state of being irradiated with normal light.

On the surface of the base material, there may be a region in which the background pattern and the first variable information are formed and the second variable information is not formed.

There may be a gap at at least one of the image line included in the background pattern and the first variable information.

The second variable information may be personal information.

In the method for producing a variable information printed matter of the present invention, a background pattern formed in at least a part of the surface of the base material and a plurality of first patterns in which the same contents are continuously formed overlapping the background pattern. When creating a variable information printed matter including the variable information of 1 and the second variable information formed so as to overlap or not overlap with the background pattern, the background pattern, the first variable information, and the second variable information are created. It is characterized in that the variable information of is printed in the same process.

The first variable information is continuously formed according to the regularity of the background pattern, or is continuously formed so as to be visually recognized as a part of the background pattern, and the second variable information is the regularity of the background pattern. Is irrelevant and may be formed so as not to be visually recognized as a part of the background pattern.

The first variable information may be continuously arranged along the image lines or halftone dots included in the background pattern.

The first variable information may include at least a part of the content of the second variable information.

According to the variable information printed matter and the method for producing the variable information printed matter of the present invention, it is possible to more effectively prevent forgery of the variable information printed matter while reducing the cost.

Hereinafter, a variable information printed matter according to an embodiment of the present invention and a method for producing the same will be described 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, each printed matter includes a background pattern 102, fixed information 103 such as ruled lines having fixed contents common to each printed matter, and personal information on the surface of the base material 101. As information having different contents for each, for example, variable information 104a such as an identification number and variable information 104b such as a personal name are formed by printing.

As the variable information printed matter according to such a comparative example, as shown in FIG. 1B, a blank printed matter in which the background pattern 102 is formed in advance on the surface of the base material 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 matter by so-called overprinting, and the variable information as shown in FIG. 1 (a). Printed matter is created.

A procedure in the case where the variable information printed matter according to such a comparative example is forged will be described with reference to FIG.

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

For such a variable information printed matter, only the variable information 104a and 104b are erased as shown in FIG. 2B, and the variable information 204a and 204b different from the genuine variable information 104a and 104b are shown in FIG. It is printed as shown in c).

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 the base material 101 as a first printing layer. After that, the fixed information 103 and the variable information 104a are printed as the second printing layer on the surface of the base material 101 on which the background pattern 102 as the first printing layer is formed.

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

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

(Embodiment 1)
As described above, in the variable information printed matter according to the comparative example, the background pattern 102 is printed in advance as the first layer, and then the variable information 104a is printed as the second layer, so that the second layer is printed. By removing only the variable information 104a as a layer and printing the non-authentic variable information 204a on the surface of the variable information 104a as a second layer, it was possible to easily forge.

On the other hand, the variable information printed matter according to the first embodiment of the present invention is shown in FIG. 4 (c) on the surface of the base material 1 on which nothing is printed as shown in FIG. 4 (b). As described above, 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, and FIG. 4A ), A variable information printed matter is created.

The background pattern 2 is formed in at least a part of the surface of the base material 1, and the variable information 2-4a and 2-4b are continuously formed by overlapping the background pattern 2 with the same contents. Has been done. In the first embodiment of the present invention, in more detail, according to the regularity of the background pattern 2, for example, the background pattern 2 is continuously arranged along the image lines included in the background pattern 2. The variable information 4a and 4b are formed so as to overlap or not overlap with the background pattern 2. In the first embodiment of the present invention, in more detail, the background pattern 2 is arranged so as not to be visually recognized as a part of the background pattern 2 regardless of the regularity of the background pattern 2. The variable information 2-4a and 2-4b include at least a part of the contents of the variable information 4a and 4b. Further, the variable information 2-4a and 2-4b have the same color as at least one of the colors included in the background pattern 2, and the variable information 4a and 4b have a color different from that of the background pattern 2.

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

First, as shown in FIG. 5A, an attempt is made to forge a variable information printed matter in 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 counterfeiter tries to remove the genuine variable information 4a and 4b, leaving the background pattern 2 and the fixed information 3 as shown in FIG. 5B. Alternatively, as shown in FIG. 5C, the background pattern 2 is left, and the genuine variable information 4a and 4b and the fixed information 3 are removed.

However, the background pattern 2 formed on the variable information printed matter according to the first embodiment of the present invention contains variable information 2-4a and 2-4b as shown in FIG. 5C. ..

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

As a result, the counterfeiter discovers that 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, identification along the image lines included in the tint block pattern or the like. Variable information 2-4a such as a book number and variable information 2-4b such as a personal name are arranged. Therefore, it becomes necessary to replace the variable information 2-4a and 2-4b arranged along the image line of the background pattern 2 with other variable information that is not genuine, which makes it more difficult to forge.

Further, unlike the conventional case, since blank printed matter is not used, it is not necessary to manage the printed matter so as not to be stolen, and the management cost can be reduced.

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

In this state, as shown in FIG. 7B, the counterfeiter attempts to remove the variable information 4a while leaving the background pattern 2 and the fixed information 3. However, in the first embodiment of the present invention, the background pattern 2, the fixed information 3, and the variable information 4a are formed as the same first print layer. Therefore, it is difficult to remove only the variable information 4a while leaving the background pattern 2 and the fixed information 3. In particular, in the portion where the variable information 4a and the background pattern 2 are in contact with each other, as shown as the region 5, ink may remain in an attempt to remove only the variable information 4a. Further, in the variable information printed matter according to the first embodiment of the present invention, as described above, variable information 2-4a and 2-4b are arranged along the background pattern 2 as the same first layer of the printed matter. With the background pattern 2 left, it is extremely difficult to remove not only the variable information 4a but also the variable information 2-4a and 2-4b and rewrite it with other variable information. Therefore, according to the variable information printed matter according to the first embodiment of the present invention, a high anti-counterfeiting effect can be obtained.

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

The variable information printed matter according to the second embodiment of the present invention has a background pattern as shown in FIG. 8 (c) on the surface of the base material 1 on which nothing is printed as shown in FIG. 8 (b). 2. All the information including the fixed information 3, the variable information 4a and 4b, and the variable information 2-4a is printed in the same process to create a variable information printed matter as shown in FIG. 8A. Here, the variable information 2-4a does not follow the regularity of the background pattern 2. More specifically, the variable information 2-4a is not arranged along the image line included in the background pattern 2. However, the variable information 2-4a is continuously arranged in a fixed direction so as to be visually recognized as a part of the background pattern 2. The variable information 4a and 4b are arranged so as not to be visually recognized as a part of the background pattern 2 regardless of the regularity of the background pattern 2.

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

First, as shown in FIG. 9A, when attempting to forge a variable information printed matter in which a background pattern 2, fixed information 3, variable information 4a, 4b, and variable information 2-4a are formed, As shown in FIG. 9B, the counterfeiter attempts to remove the variable information 4a and 4b while leaving the background pattern 2 and the fixed information 3. Alternatively, as shown in FIG. 9C, the variable information 4a and 4b and the fixed information 3 are removed while leaving the background pattern 2.

However, the background pattern 2 formed on the variable information printed matter according to the second embodiment of the present invention is formed so as to be included in the background pattern 2 as shown enlarged in FIG. 10 (b). 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 identification number included in the background pattern 2 are included according to the variable information to be forged. Must be changed.

As a result, the counterfeiter discovers that counterfeiting is difficult and discourages counterfeiting, and counterfeiting is prevented.

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 adapted to the curved lines of the tint block pattern included in the background pattern 2 and having a design property. It is arranged along the above, and the counterfeiter may not be aware of the existence of the variable information 2-4a and 2-4b.

Therefore, if the variable information 2-4a and 2-4b included in the background pattern 2 are forged by replacing only the variable information 4a and 4b without noticing, the variable information 2-4a, which is the same as the genuine variable information printed matter, 2-4b remains, and a clear difference occurs between the forged variable information 4a and 4b, so that the authenticity can be easily determined.

On the other hand, in the variable information printed matter according to the second embodiment of the present invention, the variable information 2-4a included in the background pattern 2 is not arranged along the curved line included in the tint block pattern of the background pattern 2. It is intentionally formed as an independent entity without being familiar with the curved line. Therefore, the counterfeiter easily notices the existence of the variable information 2-4a, the motivation for counterfeiting is clearly discouraged, and a high anti-counterfeiting effect can be obtained.

(Embodiment 3)
The variable information printed matter according to the third embodiment of the present invention has a background pattern as shown in FIG. 11 (c) on the surface of the base material 1 on which nothing is printed as shown in FIG. 11 (b). All the 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, and FIG. A variable information printed matter as shown in a) is created. Here, in the variable information printed matter according to the third embodiment of the present invention, different background patterns 2A and 2B are formed as the background patterns.

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

A case where an attempt is made to forge the variable information printed matter according to the third embodiment of the present invention will be considered.

When attempting to forge a variable information printed matter in which the background pattern 2, fixed information 3, variable information 4a and 4b, and variable information 2-4a and 2-4b shown in FIG. 12A are formed, The counterfeiter tries to remove only the variable information 4a and 4b and leave the other information behind.

However, the background pattern 2 formed on the variable information printed matter according to the third embodiment of the present invention contains variable information 2-4a and 2-4b as shown enlarged in FIG. 12 (b). It has been. Further, as described above, two types of background patterns 2A and 2B that are different from each other are formed as background patterns, and variable information 2-4a and 2-4b are formed in each.

Therefore, in the case of forgery, 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 are included, and the variable information to be forged is included. Must be changed according to. As a result, the counterfeiter discovers that counterfeiting is extremely difficult and discourages counterfeiting, resulting in a high anti-counterfeiting effect.

Further, 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 curved line of the tint block pattern included in the background pattern 2A and having a design property. Has been done. However, the variable information 2-4b included in the background pattern 2B is not arranged along the curved line of the tint block pattern included in the background pattern 2B and has a design property, and is intentionally independent without being familiar. It is formed. As described above, the variable information 2-4a and 2-4b formed in different modes are present in the different background patterns 2A and 2B, respectively, and the motivation for counterfeiting can be more effectively discouraged.

Further, as shown in FIG. 12A, the background pattern 2 and the variable information 2-4a and 2-4b are formed in the variable information printed matter according to the third embodiment of the present invention, but the variable information There are free areas 6a and 6b in which 4a and 4b are not formed. By the existence of the free 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 makes it possible to clearly discourage counterfeiting.

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

The variable information printed matter according to the fourth embodiment of the present invention has a specific product form configuration such as a passport, and as shown in FIG. 13A, the background pattern 2 is formed on the entire surface of the base material 1. Fixed information 3, variable information 4a, 4b, and 4c are printed in the same process in areas other than the free areas 6a, 6b, and 6c. For example, the variable information 4a represents an identification number or the like, the variable information 4b represents a personal name or the like, and the variable information 4c represents a face photograph. A boundary portion 7 exists between the variable information 4c and the background pattern 2. Variable information 2-4a is formed on the outer circumference of the boundary portion 7.

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

The boundary portion 7 is provided between the periphery of the ellipse of the variable information 4c and the background pattern 2, and a blur is formed in the boundary portion 7. When 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 out the variable information 4c into an elliptical shape and change it to another facial photograph.

Further, the variable information 2-4a and 2-4b are arranged so as to fit along the curved line included in the background pattern 2 as shown in FIG. 13B.

By providing such a configuration, forgery can be prevented more effectively according to the variable information printed matter according to the fourth embodiment of the present invention.

(Embodiment 5)
The configuration of the variable information printed matter according to the fifth embodiment of the present invention will be described with reference to FIGS. 14 and 15. FIG. 14 (a) shows an example of a contact point 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. 14 (b) shows a partial contact point A. It is shown enlarged in. In this example, the background pattern 2 and the variable information 4a are connected to each other at the contact point A. 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 a part of the background pattern 2.

FIG. 15 (a) shows another example of the contact point 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 point B. Partially enlarged and shown. In this example, there is a gap between the background pattern 2 and the variable information 4a so that the background pattern 2 and the variable information 4a are separated from each other.

The configuration in which the background pattern 2 and the variable information 4a shown in FIG. 14 are connected and the configuration in which the background pattern 2 and the variable information 4a shown in FIG. 15 are separated are in terms of visibility and design. It's different. In the configuration shown in FIG. 15, the presence of a gap at the contact point B differentiates the variable information 4a from the background pattern 2 and improves visibility.

When there is a gap between the background pattern 2 and the variable information 4a, for example, only the area where the variable information 4a of "3" exists is erased, and other areas such as "4" and "5" are deleted. When the character is changed, the relative positional relationship between the changed character and the background pattern 2 changes, and it becomes necessary to extend or erase a part of the background pattern 2. In this way, 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 anti-counterfeiting effect can be obtained. This gap may be formed in all of the background pattern 2 and the variable information 4a, but may be formed in at least one of the gaps. When a gap exists only in a limited place between the background pattern 2 and the variable information 4a, it is difficult for the counterfeiter to notice the existence of the gap and forgery becomes difficult.

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

As shown in FIGS. 16 (a) and 17 (a), as an example of anti-counterfeiting technology, for example, an infrared absorbing material is used in a vacant region where variable information 4a and 4b are not formed in advance on the surface of the base material 1. A municipal mark 9 is formed with a certain silver ink and is not visible to the naked eye when normally irradiated with light, but it overlaps with the municipal mark 9 due to a functional material such as colorless fluorescent ink that emits light when irradiated with ultraviolet rays. As described above, the word "proof" is formed, and the mark 10 of the local government is formed by a functional material such as colorless fluorescent ink in the central region where variable information is formed.

On the surface of such a base material 1, in the background pattern 2 and the background pattern 2 as shown in FIGS. 16 (b) and 17 (b), similarly to the above-described first to fifth embodiments of the present invention. Variable information 2-4a, 2-4b, fixed information 3, and variable information 4a, 4b formed so as to be familiar are printed in the same process.
