Abstract

1396719 Screened exposure RESEARCH LABORATORIES OF AUSTRALIA PTY Ltd 20 Dec 1972 [24 Dec 1971] 58944/72 Headings G2H and G2M In a method of electro-photographic recording a charged photo-conductive member is exposed twice before development, one of said exposures being through both a continuous tone transparency to be copied and a patterned screen and the other of said exposures being through the continuous tone transparency only. The image so obtained may be developed with a coloured toner and transferred to a receiving surface. The process may be repeated to produce multi-colour prints.
