Influence varnish on color indicator of the imprints

Abstract

According to the results of the research, established that the varnish layer influence on the color indicators of the prints for triad paints of different colors are quite stochastic. In general, it is possible to allocate some dependence of color change indicators of prints under layer of a matte varnish Soft Touch influence. The most expressed change in color is characteristic of mixed test fields, which visually reflected by a decrease in color saturation the image becomes brighter. Composite gray and black colors, based on the triad, lose saturation in deep shadows, and as a result become lighter. A black color, incompatible, when applying a layer of varnish acquires a chromatic part. Based on the analysis of experimental data, recommend use a comprehensive approach when varnishing printed products with Soft Touch varnish. First, it is necessary to carry out test printing on new materials to set up the effect of the varnished coating on color change. Secondly, having information about the nature of the color change, make them at the stage of prepress preparation of the original layouts. Thirdly, to select for reproduction of the image, after varnishing have minimal color differences.
