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 the anti-counterfeiting feature. The advantage is that the anti-counterfeiting feature is difficult to fake, but it needs Use of natural materials, not conducive to mass production
[0004] Another example is that the Chinese patent application number 98116462.5 discloses a structural texture anti-counterfeiting method, which uses the random structural texture of the logo substrate itself as a visible random structural feature as an anti-counterfeiting feature. logo base material
[0005] There is also a Chinese patent with the application number of 92109558.9 disclosing an anti-counterfeiting 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 by machinery are randomly splashed and dried. Anti-counterfeiting is more difficult to counterfeit, but it is still possible to counterfeit by taking pictures or scanning and then plate printing

Embodiment 1

[0023] as attached figure 1 , attached figure 2 As shown, the visible random structural features of this embodiment are arranged on the outer surface of the carton; first select a 40mm × 40mm area 1 on the outer surface of the carton, and use offset printing to print on the area 1 with a length of 36mm. Five black straight lines 2 horizontally and vertically with a distance of 9 mm form four rows and four columns of sixteen small reference squares 3 with a side length of 9 mm for identification; then apply a layer of colorless and transparent varnish 4 in area 1, The method of screen printing is used to print commercially available green UV light-curable foaming ink on the glazing layer 4. The screen plate adopts 80 meshes to form raised, randomly distributed, and randomly shaped foams. The ink layer 5 and the blank area 6, as well as the UV light-cured non-foaming ink layer 7 remaining on the surface of the glazing layer 4 after foaming, with uneven shades, random distribut...

Embodiment 2

[0026] as attached image 3 , attached Figure 4 As shown, the visible random structural features of this embodiment are arranged on the outer surface of a commercial stainless steel plate 8; first, a group of three rows and three columns of nine full-scale printing are used on the outer surface of the stainless steel plate 8 by screen printing. A circular UV light-cured transparent ice flower ink layer 9 with a diameter of 8mm, the screen plate adopts 300 meshes, and then it is cured by a UV light curing machine, and visible, similar Based on the random structure texture of the ice flower, take a picture of the group of UV light-cured transparent ice flower ink layer 9 with a digital camera, give the group of UV light-cured transparent ice flower ink layer 9 an inquiry code, and use the group of UV light-cured transparent ice flower ink layer 9 is stored in the computer query system database with the query code as the file name, and in the computer query system database, the...

Embodiment 3

[0028] as attached Figure 5 , attached Figure 6 As shown, the visible random structural features of this embodiment are set on a steel filing cabinet; select a 50mm×50mm area 10 on the outer surface of the steel filing cabinet, and first spray a layer of commercially available cracks in this area 10 Paint supporting primer 11, after it dries, spray one deck of commercially available crackle paint layer 12 on the crackle paint supporting primer 11 again, its spraying thickness is 0.5mm, in the drying process thereafter, this crackle paint layer 12 can produce many randomly distributed, random cracks 13 in length, direction and thickness, the surface of the cracked paint layer 12 is taken into a picture, an inquiry code is given to the cracked paint layer 12, and the picture of the cracked paint layer 12 is given as the The query code is stored in the computer query system database as the file name, and in the computer query system database, the query code is unique.

Abstract

The invention belongs to the anti-fake field, especially relates to a method of anti fake by utilizing the visible random structure character. The invention discloses a method of anti fake by utilizing the visible random structure characteristic an tifake method, wherein the key is that the visible random structure characteristic adopts the printing ink or paint during the printing and daubing-upprocess or the visible random structure character after the printing or daubing cup process.

Description

(1) Technical field [0001] The invention belongs to the technical field of anti-counterfeiting, in particular to an anti-counterfeiting method utilizing visible random structural features. (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 such 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 the most effective anti-counterfeiting A better anti-counterfeiting method. [0003] For example, the Chinese patent applicat...
