Abstract

The invention relates to the technical field of security paper, in particular to a production method of security paper with multiple security patterns. The security paper with multiple security patterns is produced via coating on paper, introducing preset patterns regularly through a roller type transfer coating process, and producing a plurality of layers of security information in the pattern formed via coating. Multiple security technologies are combined, and imitators must overcome all technical points to combine the security technologies for successful imitation. Therefore, the security paper cannot be imitated easily, the cost of imitation is high, high difficulties are formed for imitation of security products, and the security paper has high security performance.

Description

technical field [0001] The invention relates to the technical field of anti-counterfeiting paper, in particular to a method for making anti-counterfeiting paper with multiple anti-counterfeiting patterns. Background technique [0002] With the development of science and technology, the struggle between counterfeiting and anti-counterfeiting has become increasingly fierce. Some criminals have used high-tech means to manufacture counterfeit and shoddy goods to the extent that they are fake and genuine, disrupting the anti-counterfeiting product market, which puts higher demands on anti-counterfeiting technology. requirements. Combining the application and development of anti-counterfeiting technology at home and abroad, in order to make anti-counterfeiting products achieve a relatively ideal anti-counterfeiting state, multiple anti-counterfeiting technologies must be comprehensively applied, and in fact, currencies representing the world's highest level of public anti-counterf...
