Abstract

The invention relates to an anti-counterfeiting method for random color graphics of computers implemented by using a screen code control method, which comprises the steps of obtaining random screen codes according to the screen code control method, printing characters on a screen by using a digital printing machine, and endowing the characters or graphics with color logical labels, so that each character represents a designated and colored pattern, wherein the screen codes are symbols, ASCII (American standard code for information interchange) codes, Chinese characters, English characters, numbers or characters, and a pattern shown on an anti-counterfeiting product is in a form of a pattern printed on a specific screen or a combination of pattern and color; and the anti-counterfeiting products are anti-counterfeiting tags, anti-counterfeiting certificates and anti-counterfeiting cards. According to the invention, the copied property of anti-counterfeiting codes is completely eradicated, thereby ensuring that each code is unique and different; the safety of the anti-counterfeiting products is ensured, and consumers can carry out verification through various information channels so as to obtain a process of graphic information; and the graphic information also has the diversity changes of color, so that the counterfeiting difficulty is greatly improved.

Description

technical field [0001] The invention relates to an anti-counterfeiting method for computer random color graphics using a screen coding control method, and relates to the combination of the anti-counterfeiting technology and digital printing technology using the screen coding control method. 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. Many counterfeiters use photo...
