Been having this issue come and go for months now. Running large and smaller LP-NV plates and Fuji chemical—having trouble with plates either not cleaning up or the lighter coverage (screen) area do not show up on the plate. It seems that anything below 12% opacity sometimes shows up and sometimes does not. Burning the plates at 44-47 joules, everything is clean in imagesetter (lenses, etc.), processor has fresh chemical and water. Earlier this last year we had to increase the preheat temps. to 215 and 210, then all of a sudden we needed to decrease temps to Fuji specs of 190 and 180, don't know why. This has been driving us all nuts. I've re-linearized the press out puts; which seemed to work well for a while. We're printing at 130 and 180 lpi. I'm starting to wonder if I need to completely re-setup our CTP and start from a clean slate. The only problem with this is that the rip help menu isn't much help.
Any information would be greatly appreciated.
