company news about What is UV Coating

UV coating is a clear compound that is applied to paper wet, then instantly dried by ultraviolet light (UV coating is short for ultraviolet coating). Several types of compounds are used to coat paper; UV coating chemicals include polyethylene, calcium carbonate and kaolinite. These compounds are refined and mixed with viscosifiers that help them adhere to paper. A UV coating machine is used to apply the coating after printing.

UV coatings can vary in reflectivity and thickness, depending on the application, though a high-gloss or subtle matte UV coating are typically used for premium printing applications.
