3. Visual Performance: 3D Depth vs. Surface Frosting
When a customer holds a 3D crystal, they are looking for the “magic” of a floating image.
Green Laser Effect: High-Contrast 3D
The dots created by a Green laser are bright white and reflect light beautifully.
Shading: By varying the density of the dots (Dithering), the Green laser can create “grayscale” effects, making a 3D face look realistic with shadows and highlights.
Texture: It can recreate the texture of hair, fabric, and skin inside the glass.
UV Laser Effect: Silk Surface
The UV laser creates a “velvet” or “silk” frosting.
Precision: If you are marking a 2mm tall logo on the surface of a crystal base, UV is unbeatable for sharpness.
Contrast: On the surface, it is white and clean. Inside, it is almost impossible to see.
