The notch 7 is formed at two points symmetrically with respect to the center 8 while being radially formed at the center 8 of the mold body 6. And the center angle A of the notch part 7 is formed at 40-80 degree | times. For example, the maximum width diameter D of the fine component printing unit 2 is 0.18 to 0.22 mm, and the distance L between the centers 8 is 0.4 mm.

  Further, the halftone dot printing portion 5 is formed in the blank portion 4 other than the latent image 3, which is denser than the latent image 3, that is, the diameter d is smaller than the diameter D (d <D). The halftone dot printing unit 5 is called a flat net or the like, and has an occupied area of about 7 to 13%.

  Next, the operation of the above configuration will be described. On the surface of the base paper 1 on which the latent image 3 and the like are formed, a printing unit 12 for various information such as amounts such as letters and numbers is made. In the embodiment, “I” is displayed as the printing unit 12. When copying is performed by copying by a copying machine (not shown), the printing unit 12 is copied as shown in FIG. 3 and a latent image 3 called “COPY copying” appears on the copy paper 13. This manifestation is reproduced darkly by being painted because the cutout portion 7 in the micro component printing unit 2 cannot be reproduced at the time of copying. On the other hand, the blank portion 4 forms a halftone dot printing portion 5 that is denser than the latent image 3, so that it is difficult for copying to have a resolving power, and the background portion of the latent image 3 is reproduced lightly.

As described above, in the embodiment, corresponding to claim 1, the latent image 3 on which the character composed of the fine component printing unit 2 is displayed on the surface of the base paper 1 is printed using ink, and the fine component printing is performed. Since the cutout portion 7 is formed in the round body portion 6 whose overall plane is round , the portion 2 is compatible with the halftone dot printing portion 5, that is, a flat mesh, in terms of camouflage, and the latent portion during copying is improved. The expression of the image 3 and the camouflage effect can be enhanced.

Further, in the embodiment, corresponding to the first aspect, the fine component printing unit 2 is configured such that the notch portion 7 is formed in the round main body portion 6 whose overall plane is a round shape, so that halftone printing of the background portion is performed. The portion 5, that is, the flat net can be thinned to about 7 to 13%, and the visibility of the printing portion 12 and the writing portion in a form or the like can be improved.

  Further, in the embodiment, corresponding to claim 2, the notch 7 is formed radially at the center 8 of the round body 6, and the notch 7 is point-symmetric with respect to the center 8. By forming a plurality, it is possible to disperse the arrangement of the blank portion in the round main body 6 and to increase the diameter D of the fine component printing unit 2 as much as possible.

  Moreover, in the said Example, since the center angle A of the said notch part 7 was formed in 40-80 degree | times corresponding to Claim 3, the margin part of the suitable magnitude | size by the notch part 7 can be arrange | positioned, and fine structure The diameter D of the element printing unit 2 can be increased as much as possible. When the central angle A is smaller than 40 degrees or when the central angle A is larger than 80 degrees, it is impossible to arrange a margin part having an appropriate size.

  Further, in the above-described embodiment, the notch portions 7 of the adjacent micro-component printing sections 2 corresponding to the fourth aspect are arranged substantially in parallel with each other so that the blank portion is arranged in the same direction by the notch portions 7. It can arrange | position to camouflage property.

  In addition, since the halftone dot printing unit 5 denser than the latent image 3 is formed in the blank portion 4 other than the latent image 3 in correspondence with the fifth aspect, the fine component printing unit 2 is changed by the halftone dot printing unit 5. Can be more camouflaged.

Further, in accordance with claim 6, when the fine component printing unit 2 is set to a CIE L ^* a ^* b ^* (Elster, Aster, Biester) chromaticity diagram, a brightness value is 50 or less. By doing so, the expression of the latent image at the time of copying can be further enhanced by the contrast between the surface of the base paper 1 and the fine component printing unit 2. If the CIE L ^* a ^* b ^* brightness value of the fine component printing unit is greater than 50, the latent image is displayed and the camouflage effect is produced due to the contrast between the surface of the base paper 1 and the fine component printing unit 2. Can not be increased.

  In addition, corresponding to claim 7, the diameter D, which is the maximum width of the fine component printing unit 2, is set to 0.18 to 0.22 mm, so that a latent image at the time of copying having a size of approximately 100% is expressed. The camouflage effect can be reliably increased.

  4 to 6 show the second embodiment, and the same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  In Example 2, the latent image 3 formed by the fine component printing unit 2 is printed on the white surface of the base paper 1 using black ink, and the latent image 3 is printed on the margin 4 other than the latent image 3. A denser dot printing unit 5 is formed using black ink. A blank portion 14 is formed in the margin 4. The white portions 14 are arranged in a straight line, and are directed in two directions so as to be in one direction or intersect. Note that a pattern portion (not shown) may be provided instead of the white portion 14.

  Next, the operation of the above configuration will be described. On the surface of the base paper 1 on which the latent image 3 and the like are formed, a printing unit 12 for various information such as amounts such as letters and numbers is made. When copying is performed by a copying machine (not shown), the printing unit 12 is copied as shown in FIG. 6 and a latent image 3 of “COPY copying” appears on the copy paper 13. This manifestation is reproduced darkly by being painted because the cutout portion 7 in the micro component printing unit 2 cannot be reproduced at the time of copying. On the other hand, in the blank portion 4, a halftone dot printing portion 5 and a white portion 14 are formed which are denser than the latent image 3, so that the copying is more difficult to catch up and the background of the latent image 3 is copied. The part is reproduced thinly.

  As described above, in the above-described embodiment, similar to the first embodiment, the expression of the latent image 3 during copying, the camouflage effect, and the like can be enhanced.

  As described above, the printed matter having the anti-copying pattern according to the present invention can be applied to various uses. For example, although the example in which the white portion is formed is shown in the second embodiment, a camouflage with one additional color may be provided in addition to the white portion.
