IR AND UV LACQUERING
UV lacquering, as finishing method, represents additional value of the printed element, having both the role to establish a method to get more clients by various visual effects, and of protection against external environmental factors upon handling the end product.
In simple terms, UV lacquering represents the application over the printed document of a thin layer of material made of polymer chains which, under the action of a well defined quantity of ultraviolet radiation, develops strong connections between them getting to the rigidity (drying) of the deposited surface. The aforementioned material may present various viscosity degrees, and the end product has different brightness degrees. As well, the deposit may be selective or global, on the full surface of the printed sheet.
