In the world of label printing, the use of photopolymer CTP flexo printing plates has become increasingly popular. These plates offer a range of benefits, including high-quality print results, durability, and cost-effectiveness. In this article, we will explore everything you need to know about photopolymer CTP flexo printing plates for label printing.
What is a Photopolymer CTP Flexo Printing Plate?
A photopolymer CTP flexo printing plate is a type of printing plate that is used in flexographic printing. It is made from a photosensitive material that is exposed to UV light to create an image. The plate is then washed with a solvent to remove the unexposed areas, leaving behind a relief image that can be used for printing.
