We tried moving the GTO operator over for a couple days. He saw the same problem, but was able to mitigate it more than the main operator had. One...
Arc- No the plates look fine. We've used the same plates on both presses, and changed the platemaker since this problem started. Also, don't know...

We have been having an issue where our plates come out fine, but develop spots as soon as we start running them. We currently run a DPM Pro 400...
