Is the wicker pattern celluloid film created through a one-step molding process, or is it printed on later? Is there a noticeable difference in durability between the two processes?

The Essence of Texture Processing

Molded textures are formed directly through a metal mold during material extrusion or calendering, creating a three-dimensional relief structure that is tightly bonded to the celluloid molecules. Printed textures, on the other hand, are coated with an ink layer on the substrate surface, simulating light and shadow effects through only a flat surface.
Key Differences in Durability
Physical Abrasion Resistance: After 100,000 abrasions, molded textures experience less than 5% depth loss, while printed ink layers experience over 30% loss.
Chemical Stability: Embossed textures are resistant to neutral detergents and weak acids and bases, while printed inks are easily dissolved by solvents such as alcohol.
Aging Resistance: After 500 hours of xenon lamp aging, embossed textures maintain over 85% visual legibility, while printed textures exhibit a ΔE >15 (visible to the naked eye) due to ink fading and embrittlement.
