We are a digital printers but have started a small offset section. However we are having problems with the platemaking. We are imaging using our digital press onto Nova Sharp laser film "Peal" The problem we have is the film also images as a tint. We have tried different exposure times with no success. We are using a Parker frame & Agfa Positive plates. Could it be fogged plates or could it be old lamps in the Paker frame. Any help please advise
