We currently have a polyester plate maker and a 2-color portrait press. We plan on acquiring a landscape 4-color press and would need to upgrade our plate maker. Most runs would be short between 1000 and 5000 and every once in a while runs of approximately 25,000. I would like to go chemical free if at all possible, and would like the plate cost to be reasonable. I haven't looked at CTP technology in ten years so I am a little lost, what would you guys suggest I look at?
