Abstract

1362528 Colour electro-photography SAVIN BUSINESS MACHINES CORP 18 June 1971 [18 June 1970] 05962/74 Heading G2H The subject-matter of this Specification is substantially the same as that described in Specification 1362526 but the claims are concerned with the production of a multi-colour print by multi-stage super-imposed development using a correcting filter in at least one charging, exposing and developing stage to reduce the amount of developer deposited in the stage (to compensate for the use of impure cyan and magenta).
