There are essentially 3 methods of processing or washing out photopolymer plates. These processes include solvent wash, thermal removal, and water wash processing. The water wash plates of the past were not known necessary to be the best printing plate but they were known to resist ink swell and last a long time. In the … Read More...
Flat-Top Dots Let’s start by stating what is meant by the term flat-top dot. A flat-top dot on a photopolymer plate is one that accepts the transfer of data from an imaging device to the finished plate at a 1:1 ratio. The 1:1 imaging ratio is measured in the file, post-CDI imaging, and ultimately on the … Read More...
