Abstract
A graphic arts processor capable of processing photosensitive film and paper includes digital storage for storing a replenishment control matrix formed from a plurality of individual information matrices for different photosensitive materials. Each information matrix includes replenishment control information, an indication of whether the photosensitive material is film or paper, and transport speed control information. Selector switches select one of the individual information matrices for controlling operation of the processor. A transport speed control controls the transport speed of the processor as a function of the speed control information in the selected information matrix. The replenishment control provides replenishment of the processor fluid as a function of the replenishment control information and either film density signals from a density scanner or predetermined paper density signals. The replenishment control uses the paper density signal when the information matrix includes an indication that the photosensitive material is paper, and disables the density scanner of the processor from providing density signals. Temperature control information for both solution heaters and dryer heaters is stored separately of the information matrix. Control of the solution and dryer heaters is based upon the stored temperature control information.
