[Prior art]
Conventionally, in order to prevent forgery of this kind of cash vouchers and the like, for example, there is a method of inserting a scissors. Because Sukasi requires large-scale equipment for its manufacture, it is not easy to manufacture, and because images change by allowing light to pass through, forgery prevention can be easily performed. It is popular as an effective means.
[0003]
Scaffolds are classified into papermaking, pseudo-squat and the like depending on the manufacturing method.
The paper making scum forms an image by removing or adding a paper layer only at a specific portion during paper making. A paper layer with a paper layer removed is called a white sushi, and a paper layer with a paper layer added is called a black sushi.
The pseudo-squash is to print an image with a special transparent ink and to have an effect equivalent to that of papermaking.
[0004]
[Problems to be solved by the invention]
However, as described above, the papermaking skewer is not suitable for small-scale production because it requires large-scale equipment for production.
In addition, because of the presence of a scissors during papermaking, it was difficult to express a fine pattern.
Furthermore, because of the legal restrictions that black scales can only be used for bills, it is difficult to differentiate them from other companies' products because only white scales can be used and it is not easy to add color. Met.
[0005]
In addition, it is difficult for the above-described pseudo-squash to clarify the difference between images when the watermark is added to the light and when it is not.
Furthermore, similar things could easily be made by infiltrating the oil.

The forgery determination medium 10 includes a base material 11, a first forgery determination layer 12, a second forgery determination layer 13, and pattern print layers 14 and 15.
[0023]
The base material 11 is a base material that serves as a carrier for the counterfeit discrimination medium. When the base material 11 is transparent to light, it is necessary for the surface on the back side to be visible, and it is desirable that the opacity is about 90% or less.
[0024]
As a material of the substrate 11, paper (for example, art paper, coated paper, synthetic paper, etc.) or a plastic material that is generally used (for example, vinyl chloride, PMMA, PET, ABS, polyolefin, PET-G, polycarbonate) Acrylonitrile-styrene copolymer, cellulose propionate, cellulose acetate butyrate and the like) are preferably used.
In addition, the thickness of the base material 11 is good to determine so that opacity can be satisfied using these materials.
[0025]
The first forgery discrimination layer 12 is a layer printed on one side of the substrate 11 and has a pattern region 12a, a second pattern region 12b, and a camouflage region 12c. (Figure 1 (C))
[0026]
The pattern region 12a is a region having a regular pattern. In this embodiment, the pattern region 12a is a region of black equidistant stripes that rise 45 degrees to the left. Further, as shown in FIG. 1C, the pattern region 12a is formed in the shape of the numeral “1”.
This stripe is preferably as fine as possible. This is because the smaller the value, the more difficult it is to copy with a copying machine. Specifically, the fineness is 400 dpi or less.
[0027]
The second pattern region 12b is a region provided around the pattern region 12a, and has a pattern shifted by a half cycle from the pattern of the pattern region 12a.
[0028]
The camouflage area 12c is an area for concealing the specific shape of the pattern area 12a, that is, the formation of the number “1” in this embodiment. The pattern area 12a and the second pattern area 12b is a region having a pattern, color, etc. that cannot be discriminated visually.
In this embodiment, it has the same pitch as the pattern region 12a and a black stripe that rises 45 degrees to the right.
[0029]
The second forgery discrimination layer 13 is a layer printed on the base material 11 and is formed on the surface opposite to the surface on which the first forgery discrimination layer 12 is provided. The second forgery discriminating layer 13 has the same type of black stripes 45 degrees left as the pattern region 12a. (Fig. 1 (D))
[0030]
The pattern print layers 14 and 15 are print layers for making the portions of the base material 11 other than the first forgery discrimination layer 12 and the second forgery discrimination layer 13 opaque, and are provided on the front and back surfaces of the base material 11. It has been. The design printing layers 14 and 15 are printed with the name and design of the forgery discrimination medium 10.
Since the pattern printing layers 14 and 15 are for making the base material 11 opaque, only one of the layers may be used as long as the purpose can be satisfied.
[0031]

At this time, the user can check the first forgery discrimination layer 12, but cannot distinguish the pattern region 12a, the second pattern region 12b, and the camouflage region 12c.
[0034]
(2) The user allows the forgery determination medium 10 to pass through the light.
At this time, since the second forgery discrimination layer 13 is printed on the back surface of the forgery discrimination medium 10 as a stripe that rises 45 degrees to the left (FIG. 3B), it appears to rise 45 degrees to the right when seen through from the front side. . (Figure 3 (C))
[0035]
Accordingly, when the counterfeit discrimination medium 10 is viewed through the front side, the pattern region 12a appears to be uniformly filled by combining the black line of this region and the black line of the second forgery discrimination layer 13. (Fig. 3 (D))
[0036]
On the other hand, in the second pattern region 12b, the black line of this region and the black line of the second forgery discrimination layer 13 overlap, so even if the forgery discrimination medium 10 is watermarked from the surface side, the influence of the second forgery discrimination layer 13 is not affected. It remains the same as the original black stripe.
[0037]
In addition, the camouflage region 12c appears as a region filled with a net by combining the black line of this region and the black line of the second forgery discrimination layer 13.
[0038]
The shape of the pattern area 12a becomes visible due to the difference in lightness and darkness of these areas.
The forgery determination medium 10 has a pattern region 12a in other portions of the first forgery determination layer 12, and when the forgery determination medium 10 is seen through, the shape of the other pattern region 12a is also visible. . (Fig. 4)
[0039]
(3) The user can see the number “1000” on the forgery determination medium 10.
(4) Since the shape of the pattern region 12a is made visible by making the forgery determination medium 10 transparent, the user can confirm that the forgery determination medium 10 is a genuine product.
[0040]
According to this embodiment, since the shape of the pattern region 12a can be visually confirmed by making the forgery determination medium 10 transparent, the user can easily confirm that the forgery determination medium 10 is a genuine product.
Moreover, since the 1st forgery discrimination layer 12 and the 2nd forgery discrimination layer 13 are formed by printing, even if it is a comparatively small-scale production, it can implement suitably. In addition, coloring is easy, and differentiation from other companies' products can be achieved. In particular, when a dark color such as black, cyan, magenta, or the like is used, the shape of the pattern area 12a can be easily confirmed, and authenticity determination can be easily performed.
