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.

UV coating can be applied to your entire product, both front and back, or just on one side. You can also opt for spot UV coating, in which an ultraviolet coat is applied only to certain spots on your design (a great way to make logos or photos stand out).
