Laser labels security principle: laser anti-counterfeit laser known, or known as laser holographic anti-counterfeiting. Laser anti-counterfeit laser holographic anti-counterfeiting technology, including encryption and laser anti-counterfeit laser holographic lithography image security technology in three areas. Holographic anti-counterfeiting technologies include:. A conventional holographic anti-counterfeiting technology, the image is clear, colorful, three-dimensional sense, single-use features. b. Multi-channel holographic anti-counterfeiting technology, when rotating logo, you will see there are different patterns in the same position on the logo. c. Stealth encryption technology to encrypt pattern produced in any location identified under the laser instrument reproduction encryption pattern seen before. d.360 ° computer dot matrix hologram technology, the image observed within the range of 360 ° occurs in combination with transform radial, annular, spiral, etc. of the light spot, dynamic strong. e. double holographic technology, the holographic label opened, you can still see a pattern and text printed on a second layer of security, anti-counterfeiting effect double insurance.
