press calibration August 10, 2017, 11:35:58 AM Well, the management finally decided to calibrate our plates to the presses.Our Komori 5 colour was measured and calibration curves were input to the rip for each of CMYK.Our Komori 4 color pressman was away on holidays and his press did not get calibrated, he's been running linear plates for years with no big complaints. Boss says give him the same curves for the plates as the 5 colour but he is having a hell of a time making his work look good now. We have had to bump up his calibration curves a lot for him to get good colour. We're still trying..... next trial is a dot gain in the 50 percent area of about 8 percent. The other press is about 18 percent which seems about normal. Both guys are running the same Agfa Azura plates. They are running up the proper ink densities on the color bars....up to spec.Question is.... could 2 presses be so far apart in the calibration curves they require?
