Abstract
327,283. Jos-Pe Farbenphoto-Ges. Feb. 16, 1929, [Convention date]. Plates and films.-A film or plate for the production of wash-out gelatin reliefs is coated with a mixture of a small proportion of higbly sensitive silver halide emulsion with a large proportion (85 per cent-95 per cent) of a less sensitive emulsion. The film may be subjected to pre-exposure to uniform light from the support side, and a powerfully acting screen colouring material mav also be added to modify the height of the relief.
