AI Technical Summary
Existing holographic paper is prone to color differences during the printing process, has imprecise light control, poor holographic effect, and the grating layer is easily damaged, affecting visual effects and anti-counterfeiting functions.
The light is adjusted by the material properties of the array layer, the microlens performs secondary focusing and refraction, the honeycomb support block stabilizes the position of the microlens, the multi-level structure precisely controls the light, and the built-in slots, moving blocks, rubber pads and springs buffer external forces and protect the grating layer structure.
Enhance the visibility and color vibrancy of the laser paper, maintain a stable low color difference effect, protect the grating layer from damage, and ensure the stability and consistency of the laser effect.
