Offset UV Curing Machine

Materials. The plates used in offset printing are thin, flexible, and usually larger than the paper size to be printed. Two main materials are used: Metal plates, usually aluminum, although sometimes they are made of multi-metal, paper, or plastic.The UV Dry-Offset printing, also called waterless, is a process where the relief surface of the photopolymer transfers the ink on a blanket and subsequently the inked image on a substrate, such as the polypropylene containers.Ultraviolet curing (commonly known as UV curing) is a photochemical process in which high-intensity ultraviolet light is used to instantly cure or “dry” inks, coatings or adhesives. UV formulations are liquid monomers and oligomers mixed with a small percent of photoinitiators, and then exposed to UV energy.
