    After the holidays and vacation, I come back to the same problem. We have run more plates for our smaller press, which uses 6 mil plates, and they all work perfectly. The box of 8mil plates though is still hit and miss throughout the box. I am notices that even if I had process them, they have splotchy areas where the background doesn't come off. Wouldn't the fact that the smaller plates work fine rule out the machine?

      Could the error: LD Power deviated from target power Ch. 0.1.2.3 cause problems like I am describing? We have gotten that twice.

        Looks like a bad batch of plates. usually the thermal plates are not that sensitive to light. On the other hand CTCP or UV plates are more sensitive to light.

          Agfa is not advanced Plate. This is negative plate - Write to Print. Put clear plate (no image) to print maschine, and run. No images = clear paper. Calibration
          If its gets dirty, may be it is problem with water (osmose) or fount - changing water.
          The best plate ist Sonora Kodak. No problem, no chemistry, large range sensitvity.

            I have been running these plates for years and never had a sensitivity problem, you could have a bad batch. What is the use by date on the box? These only really have about a year shelf life.

              I thought I would follow up and let others know what we found out. Our problems seem to have been with our Crestline dampening system hitting the plates with ink and water at the same time. While this works just fine on Kodak Sanora XP that we had been running, with the Azura TE plates it didn't. If before mounting, we simply use Agfa's washout gum solution to clean the plates everything works great.

                The Azura plate is not designed for roll-up developing on press, whereas the Sonora plate is.

                  We were told the TE should work. We are switching to Sonora.
