METHOD TO SELECT COMPONENTS OF PRINTING SYSTEM FOR OPTIMAL COLOUR RENDITION IN MULTICOLOUR PRINTING

摘要

FIELD: printing industry.;SUBSTANCE: proposed solution discloses the method to select components of a printing system for optimal colour rendition, which consists in design of an original, assessment of its colour characteristics, selection of optimal components of the printing system, verification of compliance between a printing impression and an original image and run printing. At the same time the printing system is previously tested, and colour triangles are built. Assessment of colour characteristics of the original is carried out on the basis of an electronic copy of the original. Modelling of colour characteristics of the original and characteristics of the printing system is carried out in a uniform colour space. Printing system components are selected by comparison of original and printing system characteristics modelled in the uniform colour space. When detecting groups of elements arranged outside a colour triangle of the printing system, a combination of printing system components is selected, at which the vast majority of elements will be absorbed with a colour triangle of the printing system.;EFFECT: reduced capital intensity of printing system components selection providing for colour rendition without distortion and with optimal colour rendition.;8 dwg
