Coating Proofing Printers

Description of Coating Proofing Printers
Coating proofing printers are designed for professional printing, packaging, and design industries to accurately simulate final print jobs, test different coatings, or create contract proofs before mass production.

In today's efficient production methods, Roll-to-Roll coating, printing, and lamination are being used in various new materials, new products, and new technology areas. Especially the production methods of functional film as substrate, masterbatch coating, micro-nano embossing, and printing and lamination.

Flexible display: Application of PI (polyimide) transparent films and micro-nano structures, and verification of the possibility of quantum dot printing production.
Flexible circuit boards: Design and material manufacturing of circuit boards.
Flexible batteries: Charging speed and energy density of lithium batteries.
Carbon composite materials: Application of coating fluids and composite technologies.
