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-counterfeiting card, each graphic or number corresponds to a related graphic or number, and the color information is directly fed back to consumers ...
