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 if I've noted this yet, but the operator on this press had the same problem on the same model at the last place he worked. We never had it until he showed up. That, along with everything else, indicates to me that it's operator related. The DPM went from a 2508 to a 400 Pro a couple months ago. Problem didn't change when we had the new one installed.
