1. Marking security ink
Marking anti-counterfeiting ink system includes intelligent anti-counterfeiting ink, ink, identification device, etc. It is a high-tech product that combines new energy spectrum (infrared spectroscopy, nuclear energy spectrum, etc.) analysis technology and computer technology. It is mainly manifested in the variability of security materials, that is, the material consists of a variety of variable chemicals. Intelligent detection instruments, due to the use of confidential detectable substances, in the instrument through the computer-specific interface, plug board, software program to control the detection instrument window photosensor detection signal, complex digital logic spectrum processing, to achieve a special intelligent anti-counterfeiting authentication Instrument to determine qualitative, quantitative, signal alarm uniqueness. For example, the invisible anti-counterfeiting ink has its anti-counterfeiting principle by adding invisible marks such as Isotag and Coircode to the general ink. Its anti-counterfeiting feature is due to the fact that these marks are invisible, and only when professionals and certain instruments and light of a specific wavelength irradiate the specific marks appear, and thus the authenticity thereof can be identified. Its technical content is higher and its anti-counterfeiting performance is better.
2. Chemical encryption ink
Chemical encryption ink anti-counterfeiting principle is the addition of specific compounds in the ink. Its anti-counterfeit feature is to display a concealed image or generate fluorescence immediately after applying a decryption chemical reagent within a predetermined range. Different temperatures and pressures have different combinations of encoding and decoding. It can also be used to prevent alteration, and its anti-counterfeiting principle is to add chemicals to the ink or chemical substances that have a color reaction. The anti-counterfeiting feature is that when the correction fluid such as the eraser is encountered, the anti-printing shading will appear discolored or discolored. When encountering correction fluid such as erasing spirit, the printed matter has the differences of fading, coloration and discoloration. The anti-flood and anti-counterfeiting ink must have the following anti-counterfeiting characteristics: It has a color reaction to chemicals used for alteration.
