Abstract
792,361. Colour screen photography. BARVE, V. R. July 2, 1954 [May 6, 1953], No. 12681/53. Class 98(2) Substantially identical colour screens are made by exposing a colour plate or film in contact with a multicolour particle filter and processing as to a positive of the filter. The particles of the filter may be of starch coloured with the primary colours and may be caused to adhere with aid of gelatin to a transparent strip or tape as of regenerated cellulose which forms the support of the filter. Register marks or guides in the form of crosses may be provided on the filter and consequently printed on the screens. An appropriate plate or film may be exposed through one of the screens, developed to black and white, printed to form a positive thereof and the positive projected through the same or another one of the screens in register.
