いる。Many of the anti-counterfeit measures described in the prior art can be duplicated photolithographically, and it is difficult to achieve complete anti-counterfeit measures. The present invention, unlike these conventional techniques, can recognize a unique moire only when viewed from a certain specific angle, and it is extremely difficult to forge and falsify by color copying or a photographic method, and
It is an object of the present invention to provide a printed matter having a high anti-counterfeiting and tampering prevention effect and a manufacturing method thereof, which enables anyone to judge the authenticity.

線をオフセット印刷する方法である。[Means for Solving the Problems] In order to achieve the above-mentioned object, offset printing is performed on a line formed by lines of a color ink, such as straight lines, wavy lines and concentric lines, which are colorless and transparent. Intaglio printing is performed by changing the angle of the lines of lines that are the same or different from the lines used for offset printing with ink. This print is only when viewed from a certain angle
Can recognize specific moire. There are two ways to obtain this printed matter. One is a method in which an image line composed of colored lines is offset-printed first, and after the ink is completely dried, an intaglio image line composed of colorless and transparent lines is printed.
On the other hand, first print the intaglio line consisting of colorless and transparent lines,
This is a method in which after the ink is completely dried, the image lines composed of colored lines are offset printed.

色透明な凹版インキが得られる。When an intaglio printing is performed with a colorless transparent ink on an offset printing image formed by lines having a constant interval, such as colored straight lines, wavy lines, concentric lines, etc. It plays the role of a lens, and the position of the image lines due to offset printing looks slightly different when the printed matter is viewed obliquely and when viewed from the front.By printing at different angles, it is possible to print from a specific angle. Only when you see it, you can recognize the unique moire. On the other hand, on the contrary, when the colorless and transparent intaglio printing consisting of lines is performed first, the lines of the offset printing consisting of colored lines printed on the intaglio line are printed higher than the printing paper surface. , When viewed from an oblique direction, it looks slightly displaced, and the transferability of offset ink to printing paper and the transferability to the colorless transparent intaglio ink image line are different, and the transfer amount to the colorless transparent intaglio ink image line is slightly large. Therefore, the density of the offset ink on the colorless and transparent intaglio ink image line becomes high, and moire occurs. As the colorless transparent intaglio ink, it is necessary that the transparency of the vehicle is high, UV and EB curable inks containing acrylate as a main component are suitable, and in order to further improve printability, refraction of acrylate A colorless and transparent intaglio ink can be obtained by adding an extender pigment having a refractive index similar to the refractive index.

An image line consisting of the straight lines 1 shown in FIG. 1 (a) is offset-printed using a colored ink and completely dried, and then the image line of FIG. 1 (a) is obtained as shown in FIG. 1 (b). On the other hand, an image line consisting of straight lines 2 whose angle was slightly changed was intaglio printed with a colorless transparent ink. As shown in FIG. 2, the obtained printed matter 3 can only see the straight line 1 offset-printed using the colored ink when viewed from the front, but when viewed from an oblique direction, moire 4 is generated as shown in FIG. Also,
On the contrary, after the intaglio printing of the line composed of the straight lines 2 using the colorless transparent ink, the angle of the lines is slightly changed, and the lines made of the straight lines 1 are offset-printed using the colored ink. did. When viewed from the front, only the straight line 1 which is a colored image line of the obtained printed matter 3 was visible, but when viewed from an oblique direction, moire 4 as shown in FIG. 3 was generated.

ある。As described above, in products requiring anti-counterfeiting such as banknotes, passports, securities, cards, etc., tampering prevention and authenticity determination, only when viewed from a certain direction, Since recognizable moire can be formed, it is possible to obtain a printed material that is extremely difficult to forge and falsify. A copy such as a color copy forms a complicated moire, and the authenticity can be easily determined depending on whether or not the moire is generated depending on the viewing angle. As described above, it is difficult to reproduce the effect of the printed matter produced by combining the image lines of the colored lines and the image lines of the colorless and transparent lines with a copying machine and photoengraving. It is very effective as a counterfeiting and tampering prevention measure for banknotes, passports, securities, cards, etc.
