Micro-nano Anti-counterfeiting Technology
Using the lens imaging principle and optical Moire effect, applying the world’s most advanced micro-nano optical processing technology to make master plate (its processing accuracy and difficulty is comparable to that of semiconductor chip), and then through accurate pairing and the use of optical zoom effect to achieve a multi-layer structure of anti-counterfeiting technology. Also can make up and down, orthogonal drift, left and right switch, Scan scan and other effects, its anti-counterfeiting strength can be comparable to the level of banknote anti-counterfeiting.
Here Are Some Common Micro - Nano Structure Hidden Technical Effects
1. Micro-graph and Micro-text
For LOGO images or text with a height of 50~150um, 10~ 40x handheld magnifying glass or mobile phone macro camera can be used to observe the miniature information. This technology can be used for first-line, second-line anti-counterfeiting.
2. Hyperfine miniaturization
For LOGO images or text with a height of 20~50um, can be observed by a magnifying glass of 40~100 times or a macro camera of a mobile phone.
3. Information fiber
Fiber line is anti-counterfeit paper process, random distribution, often made of fluorescent multicolor, widely used in the RMB and other ticket industry.
Macroscopic view of information fiber is a fiber line, 40 times magnification can be seen a string of distorted phrase, fiber line width and text height, usually 150~300um. This technology can be used for two - line, three - line anti-counterfeiting. To the miniaturized information, can be used for two - line, three - line anti-counterfeiting.
4. Trajectory rotation
Under ordinary light source, the appearance shows a closed-loop scratch track, illuminated by a small light source such as a shaking mobile phone flashlight, presenting graphic and text information and rotating along with the scratch track. Suitable for use with circular or oval contour edges. It is characterized by the need to occupy a certain area and can be used for first-line and second-line anti-counterfeiting.
In addition, there are like metacharacters, laser reproduction, diffraction characteristic pattern, 3D torsion and other micro-nano techniques.
