We have a 4 year old Agfa Palladio platesetter and have recently noticed a large variance in dot values across the width of the plate (Agfa LapV plates). We had some variances to a small degree from the start, but Agfa says this is normal for this machine, and it appeared to be within tolerances. However, it is now well out of tolerance, with at least a ten percent difference in the 50 percent dot, from the gripper edge of the plate to the center of the plate, and then even more differences to the tail of the plate. Would some recalibration help this, along with cleaning the optics, or does this point to possible laser end-of-life? We have cleaned the optics in the past to help eliminate distortions and other exposure issues, and we dont appear to have calibration issues for our press curve, but the inconsistent exposure along the width of the plate shows us concern. Any ideas would be most appreciated.
