Abstract
A method and apparatus for uniformly developing a graphic arts process photosensitive film by producing a uniform laminar flow of treating liquid over the surface of the film as it passes through a treatment bath. The film is conveyed vertically on a rack through the bath with a U-turn near the bottom. Treatment fluid is flowed horizontally below the U-turn. Discharge and withdrawal pipes in the treatment bath container and apertures in the rack positioned at disclosed preferred locations provide the desired flow pattern.
