Abstract

600,161. Printing kinematograph films. DEBRIE, A. L. V. C. Sept. 28, 1945, No. 25289. Convention date, Feb. 5, 1943. Drawings to Specification. [Classes 98 (i) and 98 (ii)] A strip having apertures of different light transmission for selective use between the light source and the printing gate when printing films having sections of different density is either transparent or is apertured at the desired locations, which are fitted with detachable opaque plates as of metal or plastic provided with apertures of different light transmission. These may be unscreened apertures of different sizes, or apertures of equal size covered with screens of different neutral densities. For colour work, colour screens may be associated with the said apertures.
