3D Textured Coating via Selective UV Curing

The patent extracts the 3D structure creation from the traditional embossing process by using selective UV curing of liquid polymer. Instead of applying thick adhesive layers and mechanically embossing, the method selectively cures polymer only where needed to form 3D structures, eliminating the need for heavy adhesive weights while achieving the same surface texture reproduction.

The patent replaces the mechanical embossing system with a photopolymerization-based system. Instead of using mechanical pressure and physical molds to create 3D structures, the method uses UV light activation of liquid polymer to chemically form the 3D surface texture, eliminating the need for heavy adhesive layers and mechanical embossing equipment.

The patent replaces complex mechanical embossing systems with a simpler photopolymerization process. Instead of requiring mechanical pressure applications, physical molds, and multiple embossing steps, the method uses UV light activation of liquid polymer that is already positioned on the substrate, significantly simplifying the equipment and process requirements while maintaining 3D surface texture reproduction capability.

The patent applies liquid polymer to the substrate before the 3D structuring step, allowing the polymer to be positioned and prepared in advance. This preliminary application of liquid polymer eliminates the need for complex in-situ embossing operations, as the polymer is already in place and ready for selective UV curing to form the 3D structures.

The patent applies liquid polymer uniformly across the substrate, then uses selective UV curing to create 3D structures only in specific local areas where needed. This local quality approach allows different regions of the substrate to have different surface textures and heights, enabling customization while maintaining precise registration with the printed image through controlled UV exposure patterns.

The patent replaces mechanical embossing registration systems with optical UV curing patterns. Instead of relying on mechanical alignment and physical contact for registration precision, the method uses UV light exposure patterns that can be precisely controlled to match the printed image, achieving accurate texture registration without complex mechanical alignment systems.
