Laser anti-counterfeiting, also known as laser anti-counterfeiting, or laser holographic anti-counterfeiting. Laser anti-counterfeiting technology includes laser holographic image anti-counterfeiting, encrypted laser holographic image anti-counterfeiting and laser lithography anti-counterfeiting technology. Laser holography is a stereo photography technology developed rapidly after the advent of laser in the 1960s. "Holography" means "all information", that is, compared with ordinary photography, which only records the light and dark changes of objects, laser holography can also record the spatial changes of objects.
Laser anti-counterfeiting holographic anti-counterfeiting technology includes 8 technologies:
1. Conventional holographic anti-counterfeiting technology,
2. Multi channel holographic anti-counterfeiting technology,
3. Invisible encryption technology,
4.360 ° computer dot matrix holographic technology,
5. Double layer holographic technology,
6. Fluorescence encryption holographic technology,
7. Dynamic coding anti-counterfeiting technology,
8. Telephone code anti-counterfeiting technology, nuclear micropore anti-counterfeiting technology and gene anti-counterfeiting technology, and have the characteristics of clear image, gorgeous color, strong three-dimensional sense and disposable use. When turning the logo, you will see different patterns at the same position of the logo. The invisible encryption technology makes the encrypted pattern at any position of the logo, and the encrypted pattern can be seen under the laser reproducer. The combination and transformation of radial, annular and spiral light spots will appear in the 360 ° observation range of the image, which is very dynamic. The double-layer holographic technology can uncover the holographic logo and see the second anti-counterfeiting layer printed with patterns and words, which has the anti-counterfeiting effect of double insurance.
