Problems solved by technology

[0002] Traditional electronic code anti-counterfeiting labels are anti-counterfeiting by means of numbers. These numbers are first arranged in combinations from 0 to 9. Because the numbers are very easy to be copied, plagiarized, or even decrypted
Therefore, the current digital anti-counterfeiting technology still has limitations, especially the digital anti-counterfeiting technology applied to traditional label printing, which is basically an anti-counterfeiting method formed by the combination of ordinary numbers. The combination of 10 digits from 0 to 9 and ordinary fonts cannot form an effective anti-copying and anti-plagiarism effect. Many counterfeiters use photo-plate making to fully copy the digital anti-counterfeiting technology, resulting in numbers being copied many times. Repeated copying, or counterfeiters write a set of numbers at will, because consumers cannot recognize the characteristics of the label numbers, as a result, consumers are also entering the trap of counterfeiters when they verify
[0003] At the same time, the traditional code anti-counterfeiting only changes the algorithm at the system end, and does not change the key at the production end, which makes it very easy for people to find the production rules of the key and crack it in the case of a large number of digital production
[0004] Since most digital anti-counterfeiting at this stage adopts black or monochrome digital printing, therefore, the diversity of color itself is not well used for anti-counterfeiting

Embodiment 1

[0024] An anti-counterfeiting method for computer random color graphics. The codes generated by the system key are multi-digit characters or Chinese characters, and the codes generated by the system are used as codes by a digital printing machine, and then the pattern is defined again, and the characters are marked with color logic. , so that each code represents a designated, colored pattern, wherein the code generated by the system is a symbol, ASCII code, Chinese character, English, number or symbol, and the pattern presented on the anti-counterfeit product is A pattern or combination of pattern and color that is redefined to the numbers or characters produced by the system.

[0025] In this example, figure 1 : As shown in the schematic diagram of the characters and corresponding patterns generated by the system, put the random code generated by the system key into the digital printing device, use the digital printing device to convert the system code into a pattern, and ch...

Embodiment 2

[0036] Such as image 3 Schematic diagram of an anti-counterfeit label with a grating, which is an anti-counterfeit card or an anti-counterfeit label. On the basis of Embodiment 1, an anti-counterfeit module with variable grating decoding is added on the surface of the product, and the pattern presented by the module corresponds to the printed pattern. Further improve the anti-counterfeiting performance.

[0037] Others, such as the verification method are the same as in Example 1.

Embodiment 3

[0039] Such as Figure 5 Anti-counterfeit card-schematic diagram and Figure 6 As shown in the schematic diagram of anti-counterfeit card 2, the anti-counterfeit card made by the following method, Figure 5 coded for the pattern, Figure 6 The preparation method of the anti-counterfeiting card is as follows: the code generated according to the system key is multi-digit characters or Chinese characters, and the code generated by the system is re-defined by a digital printing machine, and the characters are marked with color logic. Each code represents a specified and colored pattern, and the pattern presented on the anti-counterfeiting card is a combination of pattern or pattern and color that is redefined for the numbers or characters generated by the system.

[0040]According to the verification information provided on the anti-counterfeit card, each graphic or number corresponds to a related graphic or number, and the color information is directly fed back to consumers by ...

Abstract

The invention relates to a computer random color graphics anti-counterfeiting method. A digital anti-counterfeiting technology and a variable printing technology are organically combined. Codes generated according to a system key are multidigit characters or Chinese characters, the codes generated by the system are redefined to obtain a pattern by using a digital printer, the characters are given color logical labels, and thus each code represents a specified and colorful pattern, wherein the codes generated by the system are signs, ACSII (American Standard Code for Information Interchange) codes, Chinese characters, English letters, digits or operational symbols, and the pattern shape presented on an anti-counterfeiting product is the pattern obtained by redefining the codes generated by the system or a combination of the pattern and color. The duplication of anti-counterfeiting codes is prevented, the uniqueness of each code is guaranteed, and thus the security of the anti-counterfeiting product is guaranteed. A consumer can verify the anti-counterfeiting product through various information channels. Because pattern information also has diversified colors, counterfeiting becomes more difficult.

Description

technical field [0001] The invention relates to an anti-counterfeiting method of computer random color graphics, and relates to the combination of digital anti-counterfeiting technology and variable printing technology. Background technique [0002] Traditional electronic code anti-counterfeiting labels are anti-counterfeiting through numbers. These numbers are first arranged in combinations from 0 to 9. Because the numbers are very easy to be copied, plagiarized, or even decrypted. Therefore, the current digital anti-counterfeiting technology still has limitations, especially the digital anti-counterfeiting technology applied to traditional label printing, which is basically an anti-counterfeiting method formed by the combination of ordinary numbers. The combination of 10 digits from 0 to 9 and ordinary fonts cannot form an effective anti-copying and anti-plagiarism effect.
