I've been using a Heidelberg Prosetter 74 30mW laser with Violet photopolymer plates for over 2years. Suddenly over night, the CtP has started imaging non-image areas when we attempt to burn plates. I've verified that the processor is working correctly and have cleaned the optical head and rotating mirror on the CtP. It seems to me that the CtP doesn't recognise the non-image areas of the artwork and the whole page appears green after processing the plate whereas areas outside the artboard remain white!
Any ideas how I can resolve this issue? :confused:
