Title: Color photography
IPC: G03C7/25
Filed: 1940-09-26
Abstract: 544,100. Photographic imbibition printing processes. DEHN, F. B. (Omnicolor Pictures Corporation). Sept. 26, 1940, No. 14582. Drawings to Specification. [Class 98 (ii)] The colour density of a dyed photographically prepared gelatine imbibition printing matrix is reduced by pressing into contact for a predetermined period with a receptive surface and retaining sufficient dye in the matrix for correct imbibition printing therefrom. Three overexposed prints are made by contact or projection printing from three colour component negatives and are converted into wash-out gelatine relief. After dyeing for a sufficient time to permit complete penetration of the dye into the gelatine, the reliefs are pressed against moist gelatine-coated paper or film to remove excess dye, and are then employed to print superimposed colour component images on the final support. The method may also be applied to the two-colour process. If coated film is used to remove excess dye, the latter may be removed in weak ammonia solution and the film re-employed. The method may be employed in still or motion picture work.
