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).
Is UV coating waterproof? No, UV coating is not waterproof, but it is water resistant.
Aqueous coating vs. UV coating: Aqueous coating is water-based, and though it can be a good coating option for paper, UV coating offers greater gloss and better protection
UV coating vs. lamination: Lamination offers good protection, but the lamination process requires edge trimming – which can increase production costs. Lamination can offer waterproofing, where UV coating does not
As you can see, the UV coating process differs from other types of paper finishes and offers its own distinct advantages.
