Abstract
A replenishment control system for a graphic arts continuous-tone film processor includes a scanner which scans a light spot across the film transport path and a sensor bar for receiving the light spot. The output of the sensor bar is periodically sampled during each scan of the light spot to produce a plurality of sample values for scan. Each sample value is then converted to a density value, and the density values are summed to produce an integrated density. Replenishment control signals for developer and fix replenishment are produced as a function of the integrated density.
