Analysis on anti-counterfeiting technology of new anti-counterfeiting technology

Nowadays, various new anti-counterfeiting technologies are emerging one after another. The key to anti-counterfeiting technology is to extend the timeliness and uniqueness of anti-counterfeiting technology, and it is also the main purpose of anti-counterfeiting technology. Now the anti-counterfeiting technology mainly includes: anti-counterfeiting of printing design, anti-counterfeiting of printing paper, anti-counterfeiting of printing ink and anti-counterfeiting of printing process. Among them, the development of printing ink anti-counterfeiting technology is very good, and the application range is increasingly wide.

1. Anti-counterfeiting principle of achromatic ink

The so-called anti-counterfeiting ink is a special printing ink which is processed by a special process by adding a special performance anti-counterfeiting material to the ink binder. Anti-counterfeiting inks are mainly classified into the following types according to their anti-counterfeiting functions:

1 magnetic security ink

2 fluorescent ink and phosphorescent ink

3 reaction color ink

4 anti-altering ink

5 daylight excitation color ink

6 smart security ink

7 infrared ink

8 nanometer ink

Among them, the reaction color changing ink is an important part of the anti-counterfeiting ink, and can be further divided into: thermochromic ink, photosensitive color changing ink, moisture sensitive color changing ink, pressure sensitive color changing ink and the like. Reactive color-changing inks are chemical substances that are added to the ink under certain conditions (such as light, heat, humidity, pressure, etc.), and various chemical reactions can occur, so that the ink changes color and achieves anti-counterfeiting purposes.
