Problems solved by technology

[0003] For example, the Chinese patent application number 97126167.9 discloses a natural anti-counterfeiting method, which uses the visible random structural features of some natural materials such as marble and wood as an anti-counterfeiting feature. Natural materials, not conducive to mass production
[0004] Another example is that the Chinese patent application number 98219607.5 discloses a structural texture anti-counterfeiting marker, which uses the random structural texture of the marking substrate itself as a visible random structural feature as an anti-counterfeiting feature. Its advantage is that the anti-counterfeiting feature is difficult to fake, but it needs Specialty Marking Substrates
[0005] There is also a Chinese patent with an application number of 92109558.9 disclosing an anti-counterfeit password trademark, which uses the visible random structural features left on the label as anti-counterfeiting features, such as the traces left after the colored liquid droplets thrown out by machinery are randomly splashed and dried, which is better than digital anti-counterfeiting. Harder to counterfeit, but still possible by photographing or scanning and printing

Embodiment 1

[0024] as attached figure 1 , attached figure 2 As shown, the present embodiment is a 40mm×40mm square anti-counterfeit label, on the front of the base paper 4, five black straight lines 2 with a length of 36mm and a distance of 9mm are printed on the front side, forming four rows and four columns with sixteen sides with a side length of 9mm. The reference small squares 3 used to help identification; on the sixteen reference small squares 3, there are full-scale 80-mesh screen printing, formed when the ink passes through the screen, and finalized after UV light curing Visible random structure anti-counterfeiting features, the visible random structure anti-counterfeiting features include: raised, randomly distributed, green UV light-cured foaming ink layer 5 with random shape, blank area 6, remaining in the blank area 6 of different shades Uniform, randomly distributed and random-shaped UV light-cured non-foaming ink layer 7; an inquiry code 1 is printed on the top of the ant...

Embodiment 2

[0027] as attached image 3 , attached Figure 4 As shown, the present embodiment is a packaging carton printed with a UV light-curable ice flower ink layer; on the outer surface of the packaging carton 12, a group of three rows and three columns of nine circular UV light-curable transparent ice flower inks with a diameter of 8mm are printed Layer 13 has a visible random structure anti-counterfeiting feature on the ice flower ink layer 13, and the visible random structure anti-counterfeiting feature is a visible random structure texture similar to ice flowers formed by the ice flower ink layer 13 in the UV light curing process after printing 14; On the other surface of the carton 12, there are also printed inquiry codes, inquiry telephone numbers and inquiry websites, and the entire or part of the random structure texture 14 of the UV light-curable ice flower ink layer 13 can be obtained by using the inquiry codes by telephone or the Internet Voice description information or ...

Embodiment 3

[0030] as attached Figure 5 , attached Figure 6 As shown, the present embodiment is a steel file cabinet sprayed with crack paint; on the outer surface of the steel file cabinet 21, a layer of commercially available crack paint 15 is sprayed in a region of 50 mm * 50 mm, and on the crack paint layer 15 There is a layer of pre-sprayed crack paint supporting primer 16 below, and the thickness of the crack paint layer 15 is 0.3mm. There is a visible random structure anti-counterfeiting feature on the crack paint layer 15. The visible random structure anti-counterfeiting feature is that the crack paint layer 15 is in the drying process. Many cracks 17 formed in random distribution, random length, direction and thickness; above the cracked paint layer 15 are printed with query code 1, and below the cracked paint layer 15 are printed with query telephone 10 and query website 11. The query code 1 can obtain all or part of voice description information or picture information of ran...

Description

(1) Technical field [0001] The invention belongs to the technical field of anti-counterfeiting, in particular to an article with anti-counterfeiting features of a visible random structure. (2) Background technology [0002] Using random features as anti-counterfeiting features and querying identification information through telephone, network, mobile phone short message and other communication methods is a new type of anti-counterfeiting method developed in recent years. It has many advantages such as accurate identification and rapid query. Among these methods, digital anti-counterfeiting using random codes as anti-counterfeiting features is the most widely used at present, but the pure information characteristics of its random codes make it easy to be plagiarized and copied; using visible random structural features as anti-counterfeiting features is more effective in anti-counterfeiting. Good anti-counterfeiting method. [0003] For example, the Chinese patent application...
