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 a banknote, a passport, a securities, a card, a valuable printed matter, etc., for which forgery prevention and falsification prevention are required.

[0002]

2. Description of the Related Art Banknotes, passports, securities, cards, valuable printed materials, etc., by their nature, are required to be difficult to be forged or tampered with. As a technique for taking countermeasures to prevent the forgery, there are generally known, for example, piercing based on the thickness of a paper layer, lithographic printing on a paper, or rubbing a special substance into the paper.

[0003] The inventors of the present invention printed another printed object parallel or inclined with respect to the raised printed object on a substrate on which a raised pattern such as a line pattern was printed by intaglio printing.
A patent has already been obtained for a forgery-preventing latent image print that allows recognition of specific characters, designs, and the like serving as latent images when viewed from a direction at a specific angle with respect to the base material (Japanese Patent No. 26000).
See No. 094. )

An outline of this conventional example will be described with reference to FIGS. Intaglio printing is performed on white paper 5 with a white intaglio ink having a hiding power to form a raised straight line printing image 6 representing a pattern by partially changing the angle (FIGS. 1 and 3). , 4). On the paper 5 on which the straight line image 6 is printed, straight line images 2 (FIG. 1) and 7 (FIG. 4) composed of straight lines at regular intervals are printed with colored ink to form a latent image print. Is done.

As shown in FIG. 2, when viewed from the front, this latent image printed matter can recognize only colored lines 2 as a line, but when viewed from an oblique direction, the pattern is formed by partially changing the angle. A latent image pattern (see FIG. 3) showing a pattern can be easily confirmed at a portion where the angle formed by the raised straight line printing image line 6 and the straight line image line 2 is different.

[0006] When a printed image with a relief pattern raised on an intaglio printing is formed on a substrate, and a linear line printing image is printed on the substrate to form a latent image print, the image is obliquely printed. When observing, the latent image pattern of the relief pattern is formed at a part of the relief pattern at a different angle between the straight line printing image line 6 and the straight line image line 2 which represent the pattern by partially changing the angle. (See FIG. 5).

[0007]

The forgery prevention means of the above-mentioned generally known prior art cannot discriminate a penetrated image or the like unless the paper is seen through, and the pseudo forgery means such as a varnish is used. Due to the fact that it can be inserted, it is becoming difficult to provide a complete counterfeit prevention means.

[0008] In addition, in the above patent relating to the special latent image pattern, the forgery prevention effect is great in that the special latent image pattern is revealed by changing the viewing angle with respect to the substrate. However, since the print image to be provided to exhibit the latent image effect is a monotonous design such as a line, a wavy line, etc., it is easy to duplicate the print image, and limited banknotes, securities, etc. When the forgery prevention technology is applied to the area, the area where the special latent image pattern can be provided becomes smaller, and it is difficult to effectively develop the latent image which is a feature of the special latent image pattern printed matter and the special latent image pattern forming body. .

By the way, the above-mentioned conventional patent related to a special latent image pattern has a structure in which a specific same pattern emerges by obliquely observing a substrate provided with a latent image from one direction or the opposite direction. When viewed from another direction, such a latent image effect does not appear. For this reason, the amount of information is small in spite of the wide range of the latent image provision by the intaglio printing projection image and the line image.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems. When obliquely viewed from different directions such as up, down, left, and right, latent images of the same or different designs and colors are observed depending on the viewing direction. Recognition of patterns, diversification of printed image lines by changing their width, type, size, color, etc., and adding gradation to latent image patterns, etc., and improving the authenticity discrimination function, as well as forgery, falsification, It is an object of the present invention to realize a special latent image pattern forming body which is difficult to falsify and has an enhanced anti-counterfeiting effect.

And a line printed on the substrate on which the intaglio-printed raised image is formed by being protruded along the intaglio-printed raised image. This is given by printed image lines such as dot arrays arranged in a shape, and can be recognized by observing the base material obliquely in a direction orthogonal to the first direction.

The second latent image pattern is printed on the base material by using the intaglio printing plate, using the intaglio ink of the same color or a similar color to the base material, and extending in a direction different from the first direction. A line pattern or a relief pattern that represents a pattern by making the angle different from each other, or an intaglio printing raised image forming both a line pattern and a relief pattern, and the intaglio printing raised image is formed. Line is printed on an intaglio-printed raised object on the base material, and is printed by a printed object such as a dot sequence arranged in a line. 2
Can be recognized when obliquely observed in a direction perpendicular to the direction of.

FIGS. 6 to 10 are views for specifically explaining the basic principle of the special latent image pattern forming body according to the present invention. FIG.
FIG. 7 is a diagram illustrating the formation and generation of a first latent image pattern, and FIG. 7 is a diagram illustrating the formation and generation of a second latent image pattern. The first and second latent image patterns can be recognized when obliquely observed 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, a first intaglio printing raised image 7 forming a line pattern representing a design by partially changing the angle (inclination) on the surface of the base material 5 is formed at a pitch p1. (See FIG. 6A). FIG. 6B is a sectional view taken along the line AA ′ of FIG. More specifically, the first intaglio printing raised image 7 is printed by intaglio printing of the same color or a similar color to the base material using the intaglio printing surface, and the base material 5 is printed.
The ridges 9 are formed on the flat surface 8 so as to form a line pattern. Further, since the intaglio printing raised image 7 is printed using intaglio printing, the intaglio printing surface is provided with a concave portion of the second intaglio printing raised image, and at the same time, the intaglio printing raised image 7 '.

The first line drawing 10 is printed at a pitch p2 which is close to the pitch p1. FIG. 6 (c) shows a first line image 10 and FIG. 6 (d) shows a first intaglio printing image 7 and a second intaglio printing image 7 'of the substrate. A state in which the state in which the first line drawing image 10 is printed on the top is seen when viewed from the front is shown.

When the special latent image pattern formed body thus formed is observed from the front, the first intaglio printing raised image 7
And the second intaglio printing raised image 7 ′ cannot be recognized because it is printed in the same or similar color as the base material (the first intaglio printing raised image 7 and the second intaglio printing raised image 7 ′). The intaglio printing raised image 7 'is described for the purpose of describing the positional relationship with the first line image 10 for the sake of explanation, but cannot be actually recognized.), And as shown in FIG.

When observing the special latent image pattern forming body obliquely in the first observation direction (from the middle lower oblique front side in FIG. 6 (e)), the portion 16 of the line drawing 10 is the first intaglio. When the angle of the first intaglio printing raised object 7 is different, the portion 17 of the line object 10 is visible without being affected by the first intaglio printing raised object 7. The intersection 15 of the line drawing 10 that intersects the overlapped portion 6 appears to be shaded by the portion 6 having a different angle. As described above, when viewed obliquely, the relative position between the line drawing object 10 and the first intaglio printing raised line drawing 7 makes the line drawing object visible and hidden, and the invisible part 16, the visible part 17 and the intersection part of the line drawing object 10 are seen. 1

Next, the second latent image pattern will be described with reference to FIG. FIG. 7 (a) shows a second intaglio printing raised image 7 ', in which a first intaglio printing raised image 7 is formed as in FIG. 6 (a), and FIG. It is a BB 'sectional view of (a). Specifically, the first intaglio printing raised image 7 ′ is
Using the intaglio printing plate, the printing is carried out by using an intaglio ink of the same color or a similar color as that of the base material, so that the ridges 9 ′ are formed on the flat surface 8 of the base material 5 so as to form a line pattern. .
FIG. 7C shows the second line drawing 10 ′, and FIG.
FIG. 7 shows a state in which the state in which the second line drawing object 10 ′ is printed on the second intaglio printing projection object 7 ′ and the first intaglio printing projection object 7 is visible when viewed from the front.

(The second intaglio printing raised object 7 'and the first intaglio printing raised object 7 are described in order to represent the positional relationship with the second line object 10' for explanation. However, it is not actually recognizable.), But as shown in FIG. 7D, only the second line drawing 10 'can be seen.

When the substrate 5 is observed obliquely from a second direction (from the right front in 7 (d)) which is a direction orthogonal to the first latent image pattern, the line drawing 10 ' Part 16 '
Is invisible behind the second intaglio printing raised image 7 ',
A portion 17 'of the line object 10 is a second intaglio printing raised object 7'.
Of the second intaglio-printed raised image 7 'and the intersection 15' of the line image 10 '.
Appear darker and darker due to the portions 6 having different angles. As described above, when obliquely observed, the relative position between the line image 10 ′ and the second intaglio-printed raised image 7 ′ causes the image to be hidden, and the invisible portion 16 ′ of the line image 10 ′ and the visible portion 17 'and the intersection 15' gather to form a latent image. Base material 5 from the opposite oblique direction (from the left front side in FIG. 7D)
When observing, the brightness of this latent image can be reversed and recognized.

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 at the same location on the same substrate 5 as described above. . FIG.

As described above, the special latent image pattern forming body according to the present invention has a line drawing 1
Only 0 and 10 'can be seen (see FIG. 8 (d))
However, by obliquely observing from each of the first observation direction and the second observation direction, the latent images imparted in each direction can be seen, and by confirming the presence or absence of this latent image pattern, the true False determination is possible.

The special latent image pattern forming body according to the present invention has a basic characteristic configuration in which two latent image patterns formed in different directions from each other are provided. Combine the intaglio printing raised objects of the pattern representing the second pattern to form a latent image pattern such as its shape (width, dot sequence, characters, etc.), color, printing method, etc. of the first and second printed objects. By changing various elements (concave and convex shapes, printed image lines, etc.) in various ways, a more diversified latent image can be generated, and the effect of preventing forgery can be enhanced.

The components relating to the special latent image pattern forming body according to the present invention are as follows (I) to (IV). By combining these elements, the latent image pattern is further diversified, and The prevention function can be enhanced. (I) Configuration of irregularities formed on the substrate surface. That is, an intaglio-printed embossed pattern that is printed by being raised in an intaglio and forms a line pattern, a relief pattern, or both a line pattern and a relief pattern. (II) The shape of the printed image. That is, printed objects such as line objects, dot lines arranged in a line pattern, and the like. (III) The color of the printed image. (IV) Printing structure of printed image. Hereinafter, the components (I) to (IV) and the combinations thereof will be sequentially described.

(I) Intaglio-printed ridges forming a line pattern, a relief pattern, or both a line pattern and a relief pattern are printed on a base material such as white paper by intaglio printing. .

FIG. 11 is a view showing a specific example of an intaglio printing raised image formed on the surface of a base material. FIG. 11A is an example of a concavo-convex shape in which a pattern is represented by partially changing the angle, and shows an example in which a JP character and a cherry tree mark are represented as the pattern.

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

FIG. 11 (c) shows an example in which the characters of JP and the pattern of cherry blossoms are formed so as to be superimposed on the base material with their directions shifted in directions perpendicular to each other. In this case, when observing from the first direction (from the lower side in the figure), the latent image of the JP character can be recognized, and when observing from the second direction (from the right side in the figure), the latent image of the cherry mark can be recognized. In this way, the intaglio-printed raised image is formed on the base material, which expresses patterns such as characters and marks oriented in different directions from each other by partially changing the angle.

(II) With respect to the shape of the printing object, there are a line object and a line-like dot sequence (a sequence of a plurality of points). (1) A line drawing representing a design with a fixed width, a width that changes stepwise, or a width that changes continuously. (2) A line-shaped point sequence representing a symbol by the density of points, the size of points, or a combination thereof.

When the printing image is variously changed, the latent image pattern is diversified, and a latent image pattern that is difficult to forge can be provided. A specific example will be described below with reference to an example in which the width of a parallel line is stepwise changed with respect to an intaglio printing raised image forming a parallel line pattern.

FIG. 12 (a) is a front view showing intaglio printing ridges 7, 7 'printed on a base material 5. FIG. FIG.
(B) shows the line objects 10 and 10 'printed on the substrate 5 on which the intaglio-printed raised lines 7 and 7' have been applied, and the line objects 10 '
Are gradually changed into a wide portion 11 and a narrow portion 12. FIG. 12C shows an intaglio-printed raised image 7, 7 'which forms a line pattern representing a design by partially changing the angle of an intaglio on the surface of the base material 5 to form a pattern. 7, 7 '
A line drawing 10 ′ whose width is gradually changed from the line drawing 10, the wide portion 11, and the narrow portion 12 is printed thereon.

The line objects 10 and 10 'are parallel to the intaglio printing ridges 7 and 7' (to be precise, constitute intaglio printing ridges other than the portions 6 and 6 'which are partially different in angle). Part 1
3, 13 '). The widened portion 11 or the narrowed portion 12 of the line image 10 'intersects with the portion 6' at which the angle of the intaglio printing raised image 7 'is different from the wide portion 11 or the narrow portion 12 of the line image 10'. Extends over a portion 6 'of different angles.

Now, when the observer observes the special latent image pattern forming body from the front thereof, he can recognize all the patterns of the lines 10 and 10 'as shown in FIG. 12 (c). Although the intaglio-printed raised image lines 7 and 7 'constituting the line pattern cannot be actually observed, lines showing the unevenness are described for the sake of explanation.
However, this special latent image pattern forming body is
As shown in FIG. 12A, the observer is obliquely viewed from the front (FIG. 12).
(C) Observing from the lower front side)
The 0 portion 16 is invisible behind the first intaglio printing raised image 7, and the portion 17 of the line image 10 is not affected by the first intaglio printing raised image 7 and is invisible. The crossing portion 15 of the printed protruding object 7 at a different angle from the line object 10 appears to be shaded by the portion 6 at a different angle.

Incidentally, the special latent image pattern forming body is shown in FIG.
As shown in FIG. 12A, the observer is obliquely viewed from the front (FIG.
Observation (from the right front side of (c)) shows that
The ratio of the 0 'wide portion 11 and the narrow portion 12 hidden by the second intaglio printing raised image 7' is different, the visible portion of the wide portion 11 is large, and the visible portion of the narrow portion 12 is small, When the wide width portion 11 and the narrow width portion 12 intersect with the portions 6 having different angles, the shaded area changes. In short, if the size of many visible parts constituting the pattern is different, the gradation of the pattern will be different. As a result, a pattern with shading is generated.

The case where the special latent image pattern forming body 18 is viewed obliquely will be described. FIG. 13 (b) is the same as FIG. 9 (b) when viewed from the lower front side in the figure, and is a cross-sectional view taken along line GG ′ and HH ′ in FIG. 13 (a). Ink 1 of line drawing 10 on the surface of uneven shape portion 7
4 shows the state where 4 is attached.

FIG. 14B is a sectional view taken along the line II ′ and JJ ′ in FIG. 14A when viewed from the right front side in the figure. 14A is exactly the same as the cross-sectional view taken along the line II ′. However, the cross-sectional view taken along the line JJ ′ in FIG. 14A is the same as the cross-sectional view shown in FIG. Unlike the cross-sectional view taken along the line FF ′ in b), the visible region is widened. That is, even if the intaglio printing raised image is the same, by changing the line image, depending on the width, the ink 1 is partially hidden behind the intaglio printing raised image.
A portion 16 where the ink 4 is not visible and a portion 17 where the ink 14 is partially visible are formed, and as a result, as shown in FIGS. 13 (a) and 14 (a), a design viewed from the front (see FIG. 12 (c)). ) Can be recognized.

In any case, the special latent image patterns 17, 17 'which can be observed when viewed obliquely from the lower side as shown in FIG. 13 or from the right side as shown in FIG. Intaglio-printed raised images 7, 7 'forming a line pattern in which the portions 6, 6' having different angles are arranged in advance are formed on the surface of the substrate 5, and the intaglio-printed raised images 7, 7 'are formed on the surface. On the other hand, the special latent image pattern forming body 18 is produced by printing the lines 10 and 10 ′ in which the wide portion 11 and the narrow portion 12 are appropriately changed. By observing the special latent image pattern forming body 18 from the lower side or the obliquely right front side and confirming the special latent image patterns 17 and 17 ′, it is possible to easily determine the authenticity of the special latent image pattern forming body 18. The prevention effect can be enhanced.

In the above description, it is assumed that the base material and the printing object are relatively intelligible examples, and that the base material 6 has an intaglio-printed protruding object forming a line pattern. Has been described as a line drawing representing a design by changing the width of the line step by step.

However, the present invention is not limited to this. As the base material, a relief pattern, or an intaglio-printed raised image of both a line pattern and a relief pattern can be printed by screen printing, foam printing, or the like. Substrates made by techniques may be utilized. Further, as the print object, a print object consisting of dots, characters, and the like arranged in a line may be used. Also in such a case, although a specific description is omitted, when obliquely observed, a printed image of a pattern such as a line-shaped point or a character constitutes a relief and / or a line pattern of the base material. Intersecting with the intaglio printing raised image, a stripe pattern with gradation is generated similarly to the line image, and furthermore, partly visible or invisible due to the shape of each part of the printed image, Certain special latent image patterns can be recognized, resulting in a forgery prevention function.

(III) The colors of the first and second printing objects are
Each is printed with the following color inks. Colored ink that does not emit light, different from the color of the base material. An ink that emits light with a colored ink that differs from the color of the substrate An ink that emits light with a colorless transparent ink at normal times.

(IV) The printing structure of the first and second printing objects is as follows. Continuous color change. This is a configuration in which the hue (color density and type) of one image line continuously changes in the longitudinal direction. Partial color change. This is one in which the print image is partially composed of different colors. For this purpose, the overprinting is performed so that objects of different colors overlap with each other and the colors are partially different along the images, and a partial printing plate consisting of only a region corresponding to each color is provided for each color. There is a configuration in which after all the inks are collected on the same collective plate, all the inks are simultaneously transferred to the printing plate surface, and the color is partially changed.
