13701Re: [PPLetterpress] Buying a Platemaker, advice needed.
- Jan 26, 2014Let me step back, and add that my experience is all with steel-back plates. I keep forgetting about liquid and film-back photopolymer, which have different exposure requirements. All liquid photopolymer, and some film-back, uses an additional exposure through the back, rather than relying completely on a diffused exposure from the front.
The main difference in development is that the liquids may use a detergent bath.
