ABSTRACT:
Method and apparatus for processing dry film. The non-emulsion side of the film is placed in contact with a plate surface that is at or above the developing threshold potential of the film. A second heated plate surface, at the same temperature as the first plate surface, is placed in close non-contiguous relation with the exposed emulsion side of the film whereby the film is heated under adiabatic conditions during processing. The film is removed from the developing region and allowed to cool in air.
