A, the concept:
Security printing ink, refers to has the function of security, namely, in ink printing ink links to material properties of the special security material, the special processing technology from the special printing ink.
Second, anti-counterfeiting principle:
Through the applying different external conditions, mainly USES the light, heating, spectrum testing and other forms, to observe ink mark kind of color changes, achieve the purpose of security.
Three, type:
1) according to the security function into:
The first kind, uv inspire fluorescence ink;
The second type, sun inspire change color ink;
The third kind, thermal anti-counterfeiting ink (hot to change color ink);
The fourth class, chemical reaction change color ink;
The fifth class smartphone, read (machine experts identify) security printing ink;
The sixth class, multi-function or comprehensive anti-counterfeiting ink (laser holographic and fluorescence anti-counterfeiting ink);
The seventh class, other special security printing ink, such as light variable anti-counterfeiting ink OVI.
2) prints a different object: Indian ink. News ink, plastic printing ink, etc.
3) printing forms: divided into TuYin, intaglio printing, offset printing. Nets and water-based flexo printing ink, etc
Four, implementation methods:
With ink printing mode in negotiable instruments, product trademark printing and packaging.
Five, the advantage:
Simple operation, low cost, easy to conceal, colourful, inspection convenient (hand even change the color temperature) and reproducibility, and strong smartphone read (machine experts identify) security printing ink because detection complex, reproducibility of strong, color diversity and other advantages, is the ticket and trademark paper money, the first choice of anti-counterfeiting technology.
