Abstract

196,008. Seyfferth, E. Nov. 7, 1921. Photo-mechanical printing-surfaces; negatives, producing by means other than photography; films.-Negatives or diapositives used in the production of photo-mechanical printing-surfaces comprise a support of cellon, manufactured as described in Specifications 18189/10 and 27258/10, [both in Class 7C, Indiarubber &c.], the surface of which is treated with a weak gelatine or chromated gelatine solution, or with glacial acetic acid or acetone in order to prepare it for the reception of letterpress printing. Illustrations, previously mounted on thin cellon sheets, may be attached to the same support. Photographic films may be so employed, and these are transferred from their original supports to the thin cellon sheets by coating with a dilute solution of caoutchouc followed by a dilute solution of cellon or gelatine, cutting round the part to be transferred, coating this part with a solution of cellon, or gum arabic, pressing a thin cellon sheet thereon, and then stripping the cellon and adhering film.
