Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a special latent image pattern forming body used for banknotes, passports, securities, cards, valuable printed matter, etc. for which anti-counterfeiting and tampering prevention are required.

[0002]

2. Description of the Related Art Bank notes, passports, securities, cards, valuable printed materials, etc. are required to be difficult to be counterfeited or tampered by their nature. As a technique for applying the anti-counterfeiting measure used for that purpose, there are generally known methods such as a sheet-thickness plucking, a sheet having an uneven image, and a sheet having a special substance scrubbed into the sheet.

The inventors of the present invention print a print image on a base material having an uneven image line such as a line pattern formed by scoring or embossing in parallel or at an inclination with respect to the unevenness, and print it on the base material. And a special latent image pattern forming body capable of recognizing specific characters, patterns, etc. forming a latent image when viewed from a specific angle direction (Patent 2615401).
See the official gazette. )

The outline of this conventional example will be described with reference to FIGS. The white paper 4 is embossed with the intaglio or letterpress surface (see FIG. 4). A line pattern 1 (see FIG. 1 (a)) or a relief pattern 3 (see FIG. 1) showing a design by partially changing the angle with this embossing.
(See (c)). On the surface having a convex surface by this embossing, line drawing lines 2 (FIG. 1B) composed of straight lines at regular intervals are printed with a colored ink to form a special latent image pattern forming body.

This special latent image pattern forming body A can recognize only the colored line drawing lines 2 as shown in FIG. 2 when observed from the front, but when viewed from an oblique direction, the angles are partially different. Different striped patterns are generated at different angles formed by the line pattern 1 representing the design and the line drawing line 2 and the line pattern representing the pattern (see FIGS. 3A and 3B).
Alternatively, the relief pattern (Fig. 5) can be easily confirmed.

[0006]

The above-mentioned generally known prior art anti-counterfeiting means cannot discriminate a plowed-in image or the like unless seen through the paper, and pseudo-plow with a varnish or the like. Since it can be put in, it is becoming difficult to become a perfect anti-counterfeiting means.

Further, in the patent relating to the special latent image pattern, the effect of preventing forgery is great in that the special latent image pattern is revealed by changing the visual angle with respect to the base material. However, since the printed lines that are given to develop the latent image effect are monotonous lines, wavy lines, etc., it is easy to duplicate the printed lines, and there are limitations such as banknotes and securities. When the anti-counterfeiting technology is applied to the area, the area where the special latent image pattern can be applied becomes small, and it is difficult to effectively develop the latent image that is the feature of the special latent image pattern printed matter and the special latent image pattern forming body. .

By the way, in the above-mentioned conventional patent relating to the special latent image pattern, a structure in which a specific identical pattern is raised by observing the substrate provided with the latent image obliquely from one direction or the opposite direction thereof Therefore, when observed from other directions, such a latent image effect does not appear. For this reason, the amount of information is small in spite of the wide range in which the latent image is formed by the uneven image lines and the line image lines.

An object of the present invention is to solve the above-mentioned conventional problems. When obliquely observed from different directions such as up, down, left and right, the latent image of the same or different pattern and color depending on the direction of observation. Patterns can be recognized, and the printed lines can be diversified by changing the width, type, size, color, etc., and by adding gradation to the latent image pattern, enhance the authenticity determination function, and forge, alter, It is an object to realize a special latent image pattern forming body which is hard to be tampered with and has an enhanced anti-counterfeiting effect.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a special latent image pattern forming body according to the present invention will be described with reference to the drawings based on embodiments after explaining the basic structure.

(Basic Structure) The special latent image pattern forming body according to the present invention is basically unrecognizable when observed from the front side on the base material, but the base material is orthogonal to the predetermined first direction. If you observe it obliquely from the direction you can see the first latent image pattern,
It is a special latent image pattern forming body formed by forming two latent image patterns on a base material so that the second latent image pattern can be recognized when observed obliquely from a direction orthogonal to another second direction.

The first latent image pattern is formed on the base material by plucking or embossing, extends in the first direction, and partially extends at different angles to form a line pattern or relief pattern, Alternatively, the uneven lines that form both the line pattern and the relief pattern (in the present specification, an image with an uneven cross section is
It is called "unevenness drawing line". )) And a printing line such as a line drawing printed on the base material on which the uneven drawing line is formed so as to be raised along the uneven drawing line, or a printing line such as a dot array arranged in a line shape. It can be recognized by observing the substrate obliquely in a direction orthogonal to the first direction.

The second latent image pattern is also formed on the base material by the same staking or embossing, and extends in a direction different from the first direction and partially differs in angle to represent a pattern. Pattern or relief pattern, or an uneven drawing line that forms both a line pattern and a relief pattern, and a line drawing printed on the base material on which the uneven drawing line is formed by protruding along the uneven drawing line. It is provided by a printing line such as a line or a line of dots arranged in a parallel line, and can be recognized by observing the base material obliquely in a direction orthogonal to the second direction.

6 to 10 are views for specifically explaining the basic principle of the special latent image pattern forming body according to the present invention. Figure 6
FIG. 7 is a diagram illustrating formation and generation of a first latent image pattern, and FIG. 7 is a diagram illustrating formation and generation of a second latent image pattern. The first and second latent image patterns can be recognized by observing them obliquely from the first and second directions orthogonal to each other, and the first and second latent image patterns are formed in directions orthogonal to each other. .

The first latent image pattern will be described with reference to FIG.
In FIG. 6, the surface of the base material 5 is partially formed with different pitches (inclined) so as to form the first concave-convex image lines 7 forming a parallel line pattern with a pitch p1. (See FIG. 6A). FIG. 6B is a diagram of FIG.
It is an AA 'sectional view. Specifically, the first concave-convex drawing line 7 is formed so that the convex stripes 9 form a line pattern on the flat surface 8 of the base material 5. Also, at the same time, the uneven line 7 '
Is formed.

First parallel to the first concave-convex drawing line 7 (more precisely, parallel to the portion 13 constituting the first concave-convex drawing line 7 other than the portion 6 having partially different angles). Line drawing line 1
0 is printed at a pitch p2 that is close to the pitch p1.
FIG. 6C shows the first line drawing line 10, and FIG.
(D) shows a state in which the state where the first line drawing line 10 is printed on the first unevenness drawing line 7 and the second unevenness drawing line 7'of the base material is visible when observed from the front. ing.

When the special latent image pattern forming body formed in this manner is observed from the front, the first uneven image lines 7 and the second
Cannot be recognized (the first unevenness drawing line 7 and the second unevenness drawing line 7 ′ are the first line drawing lines 10).
It is described for the purpose of showing the positional relationship between and, but it cannot be recognized in practice. ), As shown in FIG.
Only the line drawing line 10 can be seen

When this special latent image pattern formed body is obliquely observed in the first observation direction (from the lower oblique front side in FIG. 6 (e)), the portion 16 of the line drawing line 10 has the first unevenness. It cannot be seen because it is hidden behind the drawing line 7, and the portion 17 of the line drawing line 10 is visible without being affected by the first concave-convex drawing line 7 and intersects with the portion 6 where the angle of the first concave-convex drawing line 7 is different. The crossing portion 15 of the parallel line drawing lines 10 appears to be shaded by the portions 6 having different angles. As described above, when observed obliquely, the relative position of the line drawing line 10 and the first concave-convex drawing line 7 causes the line-of-sight to be hidden, so that the invisible part 16, the visible part 17 and the intersecting part 15 of the line drawing line 10 are generated. Collected to form a latent image. When the substrate is observed from the opposite oblique direction (from the upper oblique front side in FIG. 6E), the bright and dark of the latent image appear to be reversed.

Next, the second latent image pattern will be described with reference to FIG. FIG. 7A shows a second concave-convex image line 7 ′, and FIG.
As in the case of (a), the first concave-convex image line 7 is formed.
7B is a cross-sectional view taken along the line BB ′ of FIG. First
The uneven image line 7 ′ is specifically formed so that the ridge 9 ′ forms a line pattern on the flat surface 8 of 5.
FIG. 7C shows the second line drawing line 10 ′, and FIG.
Shows a state in which the second line drawing line 10 'is printed on the second uneven drawing line 7'and the first uneven drawing line 7 and is visible when observed from the front side, and FIG. The state which can be seen when observing the base material diagonally from the second observation direction (from the right front side in FIG. 7D) is shown.

The second concave-convex drawing line 7'is specifically formed so that the ridge 9'forms a line pattern on the flat surface 8 of the substrate 5. The second concave-convex drawing line 7 ′ and the second line drawing line 10 ′ are formed in a direction orthogonal to the first concave-convex drawing line 7.

When the special latent image pattern forming body formed in this manner is observed from the front, the second unevenness image line 7'cannot be recognized (the second unevenness image line 7'and the first unevenness image line 7 '). The concave-convex drawing line 7 is described in order to represent the positional relationship with the second line drawing line 10 ', but it cannot be recognized.), As shown in FIG. Line drawing line 1
Only 0'can be seen.

Then, when the base material 5 is obliquely observed from the second direction (from right front in 7 (d)) which is the direction orthogonal to the first latent image pattern, the line drawing line 10 ' Part 1
6'is hidden behind the second uneven drawing line 7'and is invisible, and the portion 17 'of the line drawing line 10 is not affected by the second uneven drawing line 7'and thus the second uneven drawing line 7'is not visible. 'Part 6 with different angles'
The intersection 15 'between the line drawing line 10' and the line drawing line 10 'appears as a shade due to the portions 6 having different angles. Thus, when observed obliquely, the relative position between the line drawing line 10 'and the second concave-convex line drawing 7'causes the appearance and concealment of the line drawing line 10', and the invisible part 16 'and the visible part 17' of the line drawing line 10 '. And intersection 15 '
Gather to form a latent image. From the opposite diagonal direction (Fig. 7
When the substrate 5 is observed from the left front side in (d), the brightness and darkness of this latent image can be reversed and recognized.

The special latent image pattern-forming body according to the present invention is such that the first latent image pattern and the second latent image pattern as described above are provided at the same location on the same base material 5. . Figure 8
FIG. 8A shows this special latent image pattern forming body according to the present invention, and FIG. 8A shows first and second concave-convex image lines 7 and 7 ′ formed on a base material in directions orthogonal to each other. Shown in FIG.
(B) has shown the 1st and 2nd line drawing lines 10 and 10 'printed in the mutually orthogonal direction.

FIG. 8C shows the first and second parallel line drawing lines 10 and 10 'with respect to the first and second concave-convex drawing lines 7 and 7'.
When the printed state (actually, printed with a grid line drawing line as shown in FIG. 15 (a) described later) is observed from the front, the first and second line drawing lines 10 and 10 ′ are A grid-like appearance is shown (the concave-convex drawing lines 7 and 7 ′ are shown for the purpose of explaining the positional relationship with the line drawing lines 10 and 10 ′, but they are not actually visible).

FIGS. 9 and 10 show a state in which the special latent image pattern forming body according to the present invention can be seen when viewed obliquely,
FIG. 9A shows a first special latent image pattern forming body according to the present invention.
10A shows a latent image pattern recognizable when obliquely observed from the observation direction of FIG. 10A, and FIG. 10A shows a latent image pattern recognizable when the special latent image pattern formed body according to the present invention is obliquely observed from the second observation direction. A latent image pattern is shown. Further, FIG. 9B shows a state in which the line drawing line 10 is hidden by the uneven drawing line 7 when the special latent image pattern forming body according to the present invention is observed obliquely from the first observation direction. FIG. 10 (b) is a cross-sectional view of the special latent image pattern-forming body according to the present invention, which is obliquely observed from the second observation direction by the concave-convex drawing line 7 ′ and the line drawing line 1 ′.
It is sectional drawing showing the state where 0'is concealed.

As described above, the special latent image pattern forming body according to the present invention has a parallel line drawing line 1 which is orthogonal to each other when observed from the front.
Only 0, 10 'can be seen (see FIG. 6 (d))
However, by observing obliquely from each of the first observation direction and the second observation direction, the latent image provided in each direction can be seen, and the true image can be confirmed by checking the presence or absence of this latent image pattern. False discrimination is possible.

The special latent image pattern forming body according to the present invention has a basic characteristic structure in that two latent image patterns formed in mutually different directions are provided, and in addition to this, the first and second Elements that form the latent image pattern, such as the shapes (widths, dot sequences, characters, etc.), colors, printing methods, etc. of the first and second print drawing lines are combined by combining the uneven print lines of the pattern showing the second design. It is possible to generate more diversified latent images by variously changing (concavo-convex shape, print image line, etc.), and it is possible to enhance the forgery prevention effect.

The constituent elements relating to the special latent image pattern forming body according to the present invention are as follows (I) to (IV), and by combining these elements, the latent image pattern can be made more diverse and synergistic forgery can be made. The prevention function can be enhanced. (I) Concavo-convex configuration formed on the substrate surface. That is, a line pattern, a relief pattern, or a concavo-convex drawing line pattern that forms both the line pattern and the relief pattern, which are formed by embedding or embossing. (II) The shape of the printed line. That is, a line drawing line, a print line such as a dot array arranged in a line shape. (III) Color of printed line. (IV) Print line printing structure. Hereinafter, the components (I) to (IV) and combinations thereof will be sequentially described.

(I) The uneven image lines forming the line pattern, the relief pattern, or both the line pattern and the relief pattern are formed on the base material by plucking or embossing. In the case of forming by plucking, an uneven image is imparted by a letterpress surface having a line pattern, a relief pattern, or both patterns at the time of papermaking. When forming by embossing, a base material such as white paper is embossed with an intaglio plate surface or a letterpress plate surface.

FIG. 11 is a view showing a concrete example of the uneven image lines formed on the surface of the base material. FIG. 11A is an example of a concavo-convex shape in which a pattern is represented by partially changing angles, and shows an example in which JP characters and cherry blossom marks are represented as a pattern.

In the special latent image pattern forming body according to the present invention, the first latent image pattern and the second latent image pattern are provided.
(B) shows an example in which both characters have the same JP character, and the directions thereof are shifted in directions orthogonal to each other and are stacked on the base material. In this case, the latent image of the JP character can be recognized by observing from the first direction (from the left side in the drawing) or observing from the second direction (from the lower side in the drawing).

FIG. 11C shows an example in which JP characters and cherry blossom patterns are formed, and the directions thereof are shifted in the directions orthogonal to each other and are formed on the base material. In this case, the latent image of JP characters can be recognized when observed from the first direction (from the lower side in the drawing), and the latent image of cherry blossoms can be recognized when observed from the second direction (from the right side of the drawing). In this manner, the concave-convex drawing lines that represent patterns such as characters and marks facing different directions by partially changing the angle are formed on the base material.

(II) Regarding the shape of the printed image line, there are a line drawing line and a line array of lines (a line of a plurality of dots). (1) A line drawing line that represents a pattern with a constant width, a width that changes stepwise, or a width that changes continuously. (2) Dense / dense points, size of points, and a line of points in a line shape that represents a pattern by a combination thereof.

When the printed image lines are variously changed, the latent image pattern is diversified, and a latent image pattern which is difficult to forge can be provided. A specific example thereof will be described below by taking an example in which the width of the parallel line is changed stepwise with respect to the uneven image line forming the parallel line pattern.

FIG. 12 (a) shows an uneven drawing line 7,
Figure 7 shows a front view forming 7 '. FIG. 12B shows
The line drawing lines 10 and 10 'to be printed on the base material 5 having the concave-convex line drawing 7 and 7'are shown.
1 and the narrow width portion 12 are changed stepwise. 12
(C) shows uneven surface lines 7 and 7 ′ forming a parallel line pattern representing a pattern by partially changing the angle on the surface of the base material 5 by pruning or embossing, and the uneven surface lines 7 and 7 are formed. A line drawing line 10 having a width that changes stepwise from the line drawing line 10, the wide width portion 11 and the narrow width portion 12 is printed on the top.

The line drawing lines 10 and 10 'are the uneven drawing lines 7 and
7'parallel (to be exact, part 6 with different angles,
It is printed on the portions 13 and 13 'constituting the uneven image line other than 6'). A portion 6 ′ having a different angle of the uneven drawing line 7 ′ and a wide width portion 11 or a narrow width portion 12 of the line drawing line 10 ′ intersect with each other to form a wide width portion 11 or a narrow width portion 12 of the line drawing line 10 ′.
Extend so as to get over the portions 6'having different angles.

Now, when the observer observes the special latent image pattern forming body from the front side, all the patterns of the line drawing lines 10 and 10 'as shown in FIG. 12C can be recognized. The concavo-convex image lines 7 and 7'constituting the line pattern cannot be observed actually, but for the sake of explanation, the lines showing the concavo-convex lines are described. However, as shown in FIG. 13 (a), when the observer observes this special latent image pattern formed body from diagonally forward (from the lower front side of FIG. 12 (c)), the line drawing line 10 Part 16
Is hidden behind the first uneven drawing line 7 and cannot be seen.
The part 17 of 0 can be seen without being affected by the first concave-convex drawing line 7,
Portions 6 and line drawing lines 10 having different angles of the first uneven drawing line 7
The crossing portion 15 of 6 appears to be shaded by the portions 6 having different angles.

By the way, the special latent image pattern forming body is shown in FIG.
As shown in (a), the observer obliquely moves forward (see FIG. 12).
When observed from the right side of (c)), the line drawing line 1
The proportion of the thick portion 11 and the narrow portion 12 of 0'which are hidden by the second concave-convex drawing line 7'is different, the visible portion of the thick portion 11 is large, and the visible portion of the narrow portion 12 is small, and When the portion 11 and the narrow portion 12 intersect the portion 6 having different angles, the shaded area changes. In short, the gradation of the pattern changes when the size of the many visible portions forming the pattern is different. As a result, a pattern with light and shade is generated.

A case where the special latent image pattern forming body 18 is viewed from an oblique direction will be described. FIG. 13B is the same view as FIG. 9B when viewed from the lower front side in the drawing, and is a cross-sectional view taken along line GG ′ and HH ′ of FIG. 13A. The ink 14 of the line drawing 10 is attached to the surface of the uneven portion 7.

FIG. 14B is a cross-sectional view taken along the line II ′ and JJ ′ of FIG. 14A when viewed from the right front side in the figure, and is taken along line EE of FIG. 10B. 'Cross section and II'
14A is the same as the sectional view of FIG.
The cross-sectional view of J ′ is different from the cross-sectional view of FF ′ in FIG. 10B due to the influence of the wide width portion 11 of the line drawing line 10 ′, and the visible region is wide. In other words, even if the uneven lines are the same,
By changing the line drawing line, a part 16 where the ink 14 is partially hidden and a part 17 where the ink 14 is partly hidden due to the width of the concavo-convex drawing line is generated depending on the width of the line, and as a result, as shown in FIG. As shown in a) and FIG. 14 (a),
Special latent image patterns 17 and 17 'having a completely different pattern from the pattern viewed from the front (see FIG. 12C) can be recognized.

In any case, the special latent image patterns 17, 17 'that can be observed when viewed obliquely from the lower side as shown in FIG. 13 or the right side as shown in FIG. In advance, the concavo-convex image lines 7 and 7'constituting a line pattern in which the parts 6 and 6'having different angles are arranged are formed on the surface of the base material 5, and the width of the concavo-convex image lines 7 and 7'is wide. Part 11
And line drawing lines 10 and 10 'in which the narrow portion 12 is appropriately changed.
The special latent image pattern forming body 18 is produced by printing. As a result, the special latent image pattern forming body 18 is observed from the lower side or the diagonally right front side, and the special latent image patterns 17 and 1 are observed.
By confirming 7 ', it is possible to easily discriminate the authenticity and enhance the forgery prevention effect.

By the way, in the above description, regarding the base material and the printing image line, as a comparatively easy-to-understand example, it is assumed that the base material 6 has an uneven image line forming a parallel line pattern, and regarding the print image line, It has been described as a line drawing line that represents a pattern by gradually changing the width of the line.

However, the present invention is not limited to this, and as the base material, a base material in which a relief pattern, or an uneven image line of both a line pattern and a relief pattern is formed by scoring or embossing may be used. Further, as the print image line, a print image line composed of dots, characters and the like arranged in a parallel line may be used. In such a case as well, a detailed description is omitted, but when observed obliquely, printed lines of patterns such as line-shaped dots and characters form the relief of the base material and / or the line-shaped pattern. Like the line drawing line, it crosses the uneven image lines with each other to create a striped pattern with gradation, and the printed image lines may be partially visible or invisible due to the shape of each part. The latent image pattern can be recognized, and as a result, the anti-counterfeit function is generated.

(III) The colors of the first and second printed lines are
Each is printed with the following color inks. Colored ink that does not emit light, which is different from the color of the base material. Ink that emits light with a colored ink that is different from the color of the base material. An ink that normally emits colorless transparent ink.

(IV) The print structure of the first and second print image lines is as follows. Continuous color change. This is a configuration in which the hue (color density, type) continuously changes in the longitudinal direction of one image line. Partial color change. In this case, the print lines are partially formed in different colors. To do this, by overprinting, the drawing lines of different colors overlap each other and the colors partially differ along the drawing lines, and the partial plate consisting of only the area corresponding to each color is inked. There is a configuration in which the inks are collected in the same collective plate, and then all the inks are simultaneously transferred to the printing plate surface to partially change the color.
