-2A-18902/78 ABSTRACT OF THE DISCLOSURE A method for processing silver halide lithographic photosensitive materials suitable for making photolithographic plates using an automatic developing machine comprising maintaining the development activity of a photographic developer used uniform by adding a first replenisher (a) to compensate for exhaustion due to processing and a second replenisher (b) to the developer to compensate for exhaustion due to the passage of time which replenishers differ in free sulfite ion concentrations,bromide concentrations and pH in which the supplemental quantity of the replenisher (b) depends upon (i) the time interval between the beginning of the operation of the automatic developing machine and beginning of the operation of the automatic developing machine when previously operated, and (ii) the ambient temperature at which the developer was kept during the time of suspension of the development operation.
