Abstract

1529716 Half-tone printing TRIPRINT PTY Ltd 4 Nov 1975 45833/75 Heading B6C [Also in Division G2] In a method of half-tone printing involving three primary colour printing passes, four differentially angled screen images of the primary colour and black components of an original are prepared. The dot sizes of the screen images corresponding to the primary colours are reduced prior to the combining of each image with its respective black component, to form negatives from which three printing plates are made. During printing the density and volume of the inks are maintained to balance the reduction in dot-size of the primary colour components.
