Abstract

21,281. Sury, J., and Bastyns, E. Sept. 17. Colour photography. - Relates to the production of colour photographs by superposing three separately printed monochromes and consists in perforating the monochromes before their superposition in order that the colours of the underneath components may blend more easily with the superposed components. To perforate the prints a roller or rolling mill provided with points may be employed. When three wet prints are joined together, the prints are compressed in a press, as thus the colour passes through the perforations and renders the whole more homogeneous.
