Rapid Processing of a Panchromatic Negative Film by the Application of a Viscous Monobath

J. C. Barnes, W. H. Bahler, G. J. Johnston

A black-and-white camera negative-monobath processing system has been designed for use in the Eastman Viscomat Processor, Model 20. Processing of the film is accomplished by the application of a thin layer of viscous monobath at 130 F in an atmosphere saturated with water vapor. With machine speed of 18 ft/min, the entire process takes approximately 2 min dry-to-dry. The photographic quality obtained with the system compares favorably with that provided by conventional processing.
