摘要

Improvements in the photomechanical procedures to prepare multicolored mosaic supports usable for color photography, characterized in that they consist of sunning behind a mask, a layer of sensitized gelatin, in clearing it so that discontinuous colored filters are obtained and in completing the cleared parts with two other series of differently colored films, also obtained by insolation and clearance of sensitized gelatin and also characterized in that the masks used are obtained from transparent plates engraved in the manner of the diffraction gratings and whose engraved grooves are filled with an opaque material, thus presenting the plates in the form of alternately opaque and transparent bands.
