Colorless fluorescent security method

Abstract

The invention discloses a colorless fluorescent security method which comprises the following operation steps of: (1) writing or drawing personalized signatures or texts; (2) scanning and inputting the personalized signatures or texts to a computer; (3) carrying out hyperline and frequency modulation processing on the texts of an original manuscript; (4) carrying out colored superimposition processing on the texts of the original manuscript; and (5) carrying out offset printing on the modified and processed image texts of the original manuscript to obtain an anti-counterfeiting label. The invention has the advantages that the colorless fluorescent printing has hidden performance and un-knowability and is hidden without tracks; the obtained patterns cannot be copied or scanned; and the anti-counterfeiting performance of the colorless fluorescent printing is better enhanced.

Description

technical field [0001] The invention relates to an anti-counterfeiting method, in particular to a colorless fluorescent anti-counterfeiting method. Background technique [0002] Anti-counterfeiting technology is a measure to prevent copying and counterfeiting. There are many types of anti-counterfeiting technologies, mainly including laser anti-counterfeiting, query digital anti-counterfeiting labels, texture anti-counterfeiting labels, and security thread anti-counterfeiting technology. The disadvantage of laser anti-counterfeiting is that , Consumers do not have the ability to confirm the authenticity of the label, and the label is easy to forge. In the absence of comparability, 60% of counterfeit products are difficult to confirm with genuine products; for query-type digital anti-counterfeiting, because it is only printed on the surface of the paper, Therefore, it is easy to be forged, so it is often difficult to achieve the purpose of anti-counterfeiting. For texture ant...

[0002] Anti-counterfeiting technology is a measure to prevent copying and counterfeiting. There are many types of anti-counterfeiting technologies, mainly including laser anti-counterfeiting, query digital anti-counterfeiting labels, texture anti-counterfeiting labels, and security thread anti-counterfeiting technology. The disadvantage of laser anti-counterfeiting is that , Consumers do not have the ability to confirm the authenticity of the label, and the label is easy to forge. In the absence of comparability, 60% of counterfeit products are difficult to confirm with genuine products; for query-type digital anti-counterfeiting, because it is only printed on the surface of the paper, Therefore, it is easy to be forged, so it is often difficult to achieve the purpose of anti-counterfeiting. For texture anti-counterfeiting labels, fingerprints, wood grains, zebra patterns, etc. can be used, and its randomness, uniqueness and incompleteness can be used to achieve the purpose of anti-counterfeiting. But its disadvantage is that the preparation of the texture is more troublesome; security thread anti-counterfeiting paper technology includes various product bottle stickers and anti-counterfeiting labels, consumers can easily identify the authenticity by identifying whether the security thread is embedded in the middle of the paper, this type of anti-counterfeiting The imitation threshold of the product is extremely high, but its disadvantage is that it is difficult to make and easy to damage

[0003] There is also a photoluminescent colorless fluorescent anti-counterfeiting technology. Although it has the advantages of invisibility and non-scannable copying, but because the colorless fluorescent anti-counterfeiting graphic manuscripts often use the original LOGO pattern and text of the product manufacturer, counterfeiters can show it according to fluorescent irradiation. The type and size of the pattern text and size are copied in the computer production software, and then counterfeited by colorless fluorescent anti-counterfeiting printing, which not only brings economic losses but also causes inconvenience to users.
