Abstract: A system has been devised and applied to one processing machine demonstrating the principle of adapting conventional processing machines for viscous-layer development. Equipment modifications were confined to the developer system and to controlling the temperature of the developer chamber. The viscous developer was supplied by an accurate metering pump through a specially designed heat exchanger to an extrusion-type applicator, which coated a uniform layer on the emulsion. A temperature-controlled, water-saturated atmosphere was maintained in the developer chamber by recirculating water sprays to prevent heat loss from the viscous developer by evaporation. The developer was removed by a water spray between the developer chamber and the fixer section. Comparison projections show very close agreement between the results of normal and viscous-layer development. The viscous-layer development produces a somewhat crisper picture because of effects in the toe.
