Surface pattern

(Picture from VDI3400)

- The surface patterns of plastic products can provide various visual and tactile sensation based on the pattern's roughness. 
We use VDI 3400 as reference standard for surface roughness.

Color & lustre

- For painting products, you can specify commonly used RAL or PANTONE color numbers (for the Japanese market, you can refer to NIPPON COLORS) or provide samples for comparison.
