Replenishing method of development replenisher in automatic developing equipment of photosensitive lithographic printing plate

摘要

A replenishing method of a development replenisher in an automatic developing equipment of photosensitive lithographic printing plate including developing plural photosensitive lithographic printing plates having been subjected to exposure processing with a developer containing an electrolyte and a development inhibitor, which includes measuring an electric conductivity of the developer; comparing the measured electric conductivity value with a predetermined electric conductivity standard value; and when the electric conductivity value of the developer is lower than the electric conductivity standard value, replenishing a development replenisher having a concentration of the development inhibitor higher than that of the developer.
