Abstract: 411,407. Colour photography. KODAK, Ltd., Kingsway, London.-(Assignees of Tuttle, F. ; 343, State Street, Rochester, New York, U.S.A.) Jan. 30, 1934, No. 3112. Convention date, Feb. 14, 1933. [Class 98 (ii).] In a method of printing from an original lenticular film bearing colour component images on to another lenticular film, the colour component images on the original film are separately and successively illuminated and projected on to the copy so as to be separately and successively recorded in positions thereon corresponding respectively to those occupied by the colour component images on the original film. The method permits the copy to be printed on a scale equal to larger, or smaller than the original. In Fig. 1 is shown diagrammatically an arrangement of apparatus for obtaining on a film 13 a copy of an original film 10 on which the colour component images have been recorded through three colour filters, for example red, green and blue. The system comprises a pair of apertured masking plates 20, 21, secured to a shaft 22, collimating lenses 23, 24, printing objective 16 and a compensating lens 25. The lenticulated side of the film is illuminated successively from different directions 17, 18, 19 corresponding respectively to the directions of the rays from the colour filters incident on the original film when exposed. In this manner the colour component images are separately and successively illuminated. The light projected from these illuminated colour images on to the copy 13 is restricted by the masking plate 21 so that the rays will be incident on the copy only in directions appropriate to subsequent projection of the copy through colour filters. The masking plates 20, 21 are provided with arcuate slots R, G, B, r, g, b radially and angularly displaced as shown in Fig. 2, and are mechanically connected to the advancing mechanism of the two films so that after optically aligning the slots in succession for separately copying the three colour images, a solid portion of the disc 20 masks the light whilst the films are advanced to bring new frames into printing position. In a modification, the masking plates reciprocate instead of rotating. The scale of reproduction in the copy may be varied by adjusting the magnification of the rear component of the printing objective.
