ABSTRACT:
It is well known to process photographic materials in web and sheet form by passing the material through a photographic processor which comprises a plurality of processing stages. The material being processed is substantially immersed in the solution in each of the processing stages which results in the use of large volumes of processing solutions. Described herein is a multi-tank processing bath which utilizes low volumes of processing solution and in which the rate of flow of processing solution through the multi-tank processing bath is matched with the transport speed of the material being processed so that the processing solution effectively travels with the portion of the material being processed which it encounters when first introduced into the processing bath. This means that the processing solution is fully exhausted by the time it reaches the end of the processing bath and can be discarded. This ensures that each part of the material being processed has new processing solution.
