Colour and tone corrections of digitized colour pictures

Vol. 29, pp. 111-118, 1981

Abstract

Masking as a method of obtaining improved reproduction of colour and tone has been studied extensively, based on photographic and on analogue or digital scanner processing systems. However, relatively little has been published on digital masking processes, and the practice involved in commercial digital scanners leaves much to be desired. In the present paper, the principle of a novel approach to digital masking is introduced which,in particular, allows a long-scale black printer tobe prepared, ensuring stable neutral tones tobe produced in printing at all density levels. Experiments are based on the digital scanning and exposing equipment Photomation P1700 and demonstrate good control over both colour and tone, taking the shape of the characteristic curve of the recording film into account.
