AI Technical Summary
The smoothness of existing special anti-counterfeiting paper for high-security documents is generally around 30 seconds, which leads to blurred patterns and loss of details during high-precision printing. Furthermore, existing anti-counterfeiting technologies such as watermarks and security threads have a low level of anti-counterfeiting, making them easy to counterfeit.
It adopts a special anti-counterfeiting paper with high smoothness, including an anti-reflective anti-reflective film layer, a refractive coating layer, a surface smooth layer, a fluorescent fiber layer, a nano antibacterial protective layer, a three-dimensional dynamic anti-counterfeiting tape, and a magnetic induction layer. Combined with nanoparticles, it forms a gradient refractive index structure and a micron-level groove structure to enhance the anti-counterfeiting function.
It achieves high smoothness and high precision printing, and has anti-counterfeiting functions such as fluorescent fibers and chemical resistance, which enhances the anti-counterfeiting level and makes it difficult to imitate.
