Особливості додрукарської підготовки кольорових оригіналів для відтворення репродукцій трафаретним способом друку

Abstract

This article is devoted to preparation of images for creation of reproductions by screen printing. In this way, some images with next description were selected: in general, only a few colours, and some of them in the similar shades but with different lightness; images consist to areas of one-tone; images don’t contain much of thin lines. These images were recommended to print by screen printing method with using transparent inks. The artworks were separated into based colours which combine to create the full spectrum of colours needed for vibrancy prints. This stage also includes determination of the percents of ink in each colours. The elements of images were reduced to one or two colours with different lightness. At the end of prepress stage, the files must be decomposed on forms with taken into consideration numbers of overlay in each colour. This means a large number of colours can be simulated using fewer screens, reducing costs, time and set-up.
