Abstract
327,200. Chapman, W. Jan. 3, 1929. Drawings to Specification. Colour photography, multicolour screen processes.-In a process for printing from component colour-record negatives, a positive emulsion on a base bearing a regular pattern of colours is successively exposed to each negative, so that only the emulsion covering the colour on the base corresponding to the negative is exposed. In an example, the base is ruled with red, green and blue lines and a grating consisting of transparent lines and opaque lines double the width is laid over it. The green partial negative is printed with the transparent lines of the grating in register with the green lines on the base, and the remaining negatives are printed similarly, the grid being shifted between the printing. For kinematography, a film produced for example as described in Specifications 319,195 and 324,989, [both in Class 97 (i), Optical systems &c.], is projected on to a film bearing red-orange, and greenblue lines, two shutters co-operating with a grating having transparent and opaque lines of equal width being used.
