As described above, whether the unevenness due to embossing is discriminated by a large-scale machine mainly using static electricity or oblique light, or whether the unevenness due to human touching the embossing is recognized by touch. The main recognition method is one of the above methods.

However, the method using a machine requires a large size of the machine, so that it cannot be easily and promptly recognized, and in order for a person to touch the emboss and confirm it, the place and shape of the emboss can be visually confirmed. It is necessary to confirm. Therefore, there is a possibility that reproduction may be performed with pseudo embossing.

In view of the above, the present invention is intended to solve the above-mentioned problems, and although the concavo-convex pattern is difficult to see with the naked eye, when a discriminating tool is closely attached and observed or white light is emitted. Since the concavo-convex pattern can be visually recognized when it is irradiated and observed, it is possible to easily make a true / false decision by using a discriminating tool. Even if it is difficult to identify the embossed shape by printing a pattern different from the embossed shape in the same area as the embossed pattern, it is possible to easily identify only the embossed shape. The present invention proposes a method of discriminating authenticity of a patterned substrate, a substrate having a concavo-convex pattern and a discriminating tool therefor.

1 shows the basic principle of the present invention.
When the discriminator 2 is brought into close contact with the base material 1 with a concave-convex pattern and the light is emitted from the oblique direction, the irregularity of the base material due to embossing can be visually confirmed from the front by the shadow of the pattern given to the discriminator. become able to.

As an example, in the case of the base material 4 provided with the concave pattern 5 of "A" as shown in FIG. 2, when the line-shaped pattern 7 is provided on the discriminating tool as shown in FIG. As shown in FIG. 4, a discriminating tool having a line pattern is brought into close contact with the embossed surface. At this time, it is necessary to bring the surface of the discriminating tool to which the line pattern is applied into close contact with the base material. By irradiating the illumination from an oblique direction, a shadow 10 due to the line pattern of the discriminating tool is generated at the place recessed by the embossing. When this state is observed from above, in addition to the line pattern 8 of the discriminator on the concave pattern, the shadow 10 generated in the concave portion can be observed from the non-image area 9 of the discriminator, which is a concave pattern. Can be recognized.

On the other hand, in the case of a base material provided with a convex pattern by embossing, the convex tops contact the discriminating tool and the surrounding base material does not adhere to the discriminating tool. Since there is a shadow on the background, it is possible to confirm even with a convex pattern by the same method. At this time, the pattern given by the concave and the pattern given by the convex are observed as if white and black were reversed.

However, when the pattern given to the discriminating tool is a line pattern, when both the illumination direction and the observation direction are in the line direction or directly above the line, or when they are exactly the same, the generated shadow is recognized. Since the uneven pattern “A” cannot be recognized because it cannot be performed, the illumination direction and the observation direction may be arbitrary under other conditions. When the pattern given to the discriminating tool is a halftone dot pattern, the illumination direction and the observation direction may be arbitrary except the case where the illumination direction and the observation direction are exactly the same.

The light-transmissive substrate used in the discriminating tool of the present invention may be made of plastic, glass, or the like. When the pattern given to the discriminating tool is the above-mentioned line pattern, the number of lines is 150 to 300 per inch. It is possible to recognize the concave-convex pattern if there is a certain number. Besides, the same effect can be obtained with a halftone dot pattern. In the case of a halftone dot pattern, an uneven pattern can be recognized if the number of lines is 150 to 300. The halftone dot shape is not particularly limited, and square dots, chain dots, round dots, special halftone dots and the like can be used. Further, the parallel line shape is not particularly limited, and the parallel parallel line,
Wavy lines can be used. Further, each pattern to be given to the discriminating tool is required to have high opacity for generating a shadow, and if the opacity is high, white other than black is possible, and is not particularly limited. Absent.

Further, as shown in FIG. 5, by providing the printed pattern 12 on the surface on which the discriminator is brought into close contact, it is possible to improve the concealment of the concavo-convex pattern 11 when observed without the discriminator being brought into close contact. However, when the printed pattern 12 is applied using a colored ink, the discriminating tool is brought into close contact, and white light is irradiated, the visibility of the concave-convex pattern 11 is impaired, so white light is passed through a color filter or a light emitting diode is used. By using it, by irradiating light of the same color as or the hue similar to that of the colored ink, it is possible to suppress the reduction in the visibility of the uneven pattern 11 due to the printed pattern 12.
The print pattern 12 of the present invention is not particularly limited, and a color pattern, a minute character, a solid color, or an ordinary pattern can be used. The colored ink of the present invention is not particularly limited, but when the black ink is used, the effect of the present invention cannot be obtained if the printing pattern is solid.

Further, as shown in FIG. 6, the printed pattern is made of a colored fluorescent ink 15 and a colorless fluorescent ink that develops a hue similar to or close to that of the colored fluorescent ink when irradiated with energy rays such as ultraviolet rays. By forming the solid pattern 17 over the entire surface of the concavo-convex pattern, it is possible to make only the concavo-convex pattern 14 visible by making the pattern of colored fluorescent ink invisible when irradiated with energy rays such as ultraviolet rays. It should be noted that the colored fluorescent ink may use a plurality of colors in the same region as long as they develop the same color or a similar hue upon irradiation with ultraviolet rays or the like.

The concavo-convex pattern of the present invention may be applied by using an impact printer, a thermal transfer printer, laser processing or electric discharge processing, in addition to embossing press processing using a mold. Further, if the height of the unevenness is about 5 μm or more, the discrimination is possible. Further, the base material may have a smoothness that does not hinder the unevenness provided. In addition, the concavo-convex pattern is made up of characters, symbols, or patterns to improve the effect of authenticity discrimination.

As the base material of the present invention, papers, films, plastics, metals and the like can be used.

Further, as the tampering prevention technology using the present invention, for example, in the case of a check as shown in FIG. 7, a check writer or the like with a face number is used on a base material on which a specific pattern is already printed. Printing is performed by using the present invention, but by using the present invention, further tampering prevention can be performed.

FIG. 7 shows visual information 19 such as a charge number printed on a base material on which a specific pattern is printed, generally in black, and at the same time, unevenness is formed on an arbitrary place of the base material. An uneven pattern (unevenness information) 20 such as a fee number is provided. In this case, it is sufficient that the provided unevenness is difficult to see. When there is a possibility that the visible information 19 has been tampered with, the discriminator of the present invention is brought into close contact with the uneven portion, and the uneven information 20 is observed to make a comparison with the visible information 19 to see if the visible information is authentic. It can be determined whether or not.

The concavo-convex information 20 added at the same time does not have to be the same as the visible information 19 and is correlated.
For example, it may be encrypted or encoded.

[0037]

The present invention will be described in more detail below with reference to examples, but the contents of the present invention are not limited to the scope of these examples.

(Example 1) In order to give unevenness to the base material, the ink ribbon of the dot impact printer was removed so that only the marking was possible. Then, a pattern was printed on the thick coated paper to give a concave pattern by stamping to the base material. A glass plate having 150 lines of parallel lines printed on one side was used as a discriminating tool. The surface of the discriminator with parallel lines is brought into close contact with the place where the recess is provided, and white light (a flashlight is used in this example) is radiated obliquely to the discriminator and the base material for observation. By doing so, the pattern due to unevenness could be confirmed.

(Example 2) In order to impart irregularities to the substrate, the irregularities were imparted by stacking ink using a thermal transfer printer. Then, by printing characters or the like on the smooth base material, a convex pattern was applied to the base material.
In order to reduce the visibility of the concavo-convex pattern when the discriminating tool is not in close contact, it is necessary to overlap the concavo-convex pattern,
It is red when observed under visible light, and offset printing is used for pattern printing using colored fluorescent ink that emits red light when observed under ultraviolet light.It is also colorless and transparent under visible light and observed under ultraviolet light. A solid fluorescent pattern was printed by offset printing so as to cover the entire surface with a colorless fluorescent ink that emitted the same color as the colored fluorescent ink and emitted in red. 15 for the discriminating tool
A glass plate with 0 parallel lines printed on one side was used. The surface of the discriminator with parallel lines is brought into close contact with the place where the concavo-convex pattern is provided, and the discriminator and the concavo-convex base material are irradiated with ultraviolet rays from the front direction, and the pattern is printed by colored fluorescent printing. Since it was difficult to visually recognize, only the concavo-convex pattern could be confirmed.

Example 3 The ink ribbon of the dot impact printer was removed in order to give unevenness to the base material so that only the marking could be performed. Then, by stamping characters or the like on the base material having smoothness, a concave pattern was given to the base material. In order to reduce the visibility of the concavo-convex pattern in the state where the discriminating tool is not in close contact, a pattern was printed with a normal colored ink so as to overlap the concavo-convex pattern. A glass plate having 150 lines of parallel lines printed on one side was used as a discriminating tool. Place the parallel lines of the discriminator in close contact with the place where the concavo-convex pattern is applied, and pass through the color filter of the same color as the colored ink used for pattern printing from an angle to the discriminator and the concavo-convex substrate. By irradiating with the above-mentioned light and observing, the pattern formed by printing with the colored ink becomes difficult to visually recognize, so only the concavo-convex pattern was confirmed.

(Embodiment 4) When printing an amount of money on a base material such as a check in a normal black color, at the same time, a portion of the base material is printed by using a dot impact printer in which the ink ribbon is removed. Make a tick. In addition, it is better that the place to be stamped is a place that is not known at first glance. By doing so, even if the fee portion printed in black should be tampered with, the person who has knowledge about the uneven place will bring the discriminator into close contact with the uneven place, and the discriminator and the base material Since the amount of charges due to the unevenness can be confirmed by irradiating white light from an oblique direction and observing, the authenticity of the amount of charges in the black portion can be determined.

Although the present invention has been described above based on the embodiment, the present invention is not limited to this embodiment, and various other things are possible within the scope of the technical idea described in the scope of claims. Various embodiments are possible.

[0043]

EFFECTS OF THE INVENTION Although the concavo-convex pattern provided on the base material is difficult to see with the naked eye, the concavo-convex pattern can be visually recognized when observed with the discriminator in close contact or when irradiated with white light or the like. The person who knows the formation location can easily and surely make a genuine / counterfeit determination by using a simple discriminating tool, and the person who does not know the formation location of the concavo-convex pattern can see where the concavo-convex pattern is formed. It is difficult to duplicate because it is not known whether or not it is.

Further, since the discriminating tool only needs to have the size of the concavo-convex pattern to be recognized, it does not require an installation space for the discriminating device and can be portable in size. Also, the pattern of the discriminator and the lighting conditions,
As long as the observation direction satisfies a certain condition, the concavo-convex pattern may have any shape, and even when superposed with a discriminating tool, it is not necessary to strictly align and superimpose it, so it is a very easy discrimination method. Can be used.
