The objective of this effort was to correct the deficiencies of a Continuous Tone Plate and Process. A new developer was formulated. The lacquer was modified to produce the desirable results by removing the pigments and adding proper solvents and a fixing agent. To optimize press conditions, studies of various inks, blankets, fountain solutions, and press settings were made. Coating defects were minimized in the plant through implementation of stricter quality control procedures, particularly in the anodizing and coating steps. The results of this development effort are 1 A new developer which is more active and efficient with respect to silver deposition. 2 A new lacquer which is completely clear and therefore non-pigmented. The tendency towards plugging is completely eliminated. 3 Extensive testing over 100 plates of this plate system has shown good reproducibility.
