Method for supplementing replenisher for developer in automatic developing machine for presensitized plate |
摘要 |
A method for supplementing a replenisher for developer which comprises developing a large number of PS plates imagewise exposed to light with a developer composed of an aqueous solution containing electrolytes in an automatic developing machine, characterized by determining an AC impedance of the developer contained in the automatic developing machine, obtaining a correction impedance from the measured impedance value and rate of replacement and supplementing a desired amount of the replenisher to the developer when the correction impedance reaches a predetermined value. This method makes it possible to maintain a desired activity of the developer even when a large number of PS plates are processed and to relax the restriction on the incorporation of optional devices such as an autofeeder into the automatic developing machine.
