Manufacturing method of anti-fake label

Abstract

The invention provides a manufacturing method of an anti-fake label. The method comprises the following steps of: microfilming anti-fake information coding to be printed on a medium for plate making, carrying out plate making on an anti-fake pattern to be printed on the medium, printing the anti-fake information coding on a first designated position of the medium by using infrared absorbing printing ink capable of absorbing a wavelength of 720-1200nm, and then printing the anti-fake pattern on a second designated position of the same medium by using infrared laser anti-fake printing ink; or, printing the anti-fake pattern on the second designated position of the medium by using the infrared laser anti-fake printing ink, and then printing the anti-fake information coding on the first designated position of the same medium by using the infrared absorbing printing ink capable of absorbing the wavelength of 720-1200nm. The manufacturing method provided by the invention can be used for invisibly printing the anti-fake information coding and the anti-fake pattern on the same medium so as to be combined into an integrated anti-fake label, so that the printed anti-fake label is invisible for naked eyes of human. In addition, the anti-fake label is well elusive and has strong anti-fake capability, and thus the manufacturing method of the anti-fake label provided by the invention is a big advance in an anti-counterfeit technology.

Description

[0001] The invention relates to a method for manufacturing an anti-counterfeit mark, in particular to a method for manufacturing an anti-counterfeit mark used for bills, certificates and other anti-counterfeit marks with high anti-counterfeiting requirements. Background technique [0002] Existing anti-counterfeiting marks are usually printed with anti-counterfeiting images, codes, barcodes or texts that can be seen by naked eyes on the medium to be printed. Although, invisible anti-counterfeiting marks have been used now, it uses special ink to print invisible coded anti-counterfeiting marks, and then detects them with a detector equipped with an infrared camera to judge the authenticity of the anti-counterfeiting marks, such as applying The invention patents No. ZL200910136063.9 and ZL200910000647.3 both use colorless ink to print anti-counterfeiting information codes on the medium. However, with the improvement of the anti-counterfeiting level, the counterfeiting technology...
