THE ANALYSIS OF THE SUBSTRATE INFLUENCE ON THE PRINT QUALITY PARAMETERS OF SCREEN-PRINTED TEXTILE

Abstract

Textile printing is an increasingly important area of the contemporary graphic industry, and screen printing represents a dominant technique in this field. The quality of the print depends on many parameters, such as the type of substrate material or the type of printing ink. The usual way to evaluate print quality consists of an objective assessment of the color and tone of the printed image. Quality parameters, such as contrast, sharpness, and macro non-uniformity, are not associated with color reproduction, but certainly affect print quality. These parameters are directly related to the quality of the lines and raster dots, which is an integral part of any image. Therefore, when evaluating print quality, it is necessary to analyse these elements. The aim of this paper was to investigate the influence of the textile substrate on the quality of print obtained by the screenprinting technique. Digital image analysis of the scanned image of the print, appropriate software application and visual evaluation of the prints, were used to determine the print quality. The obtained results show the importance of interaction between the textile material and printing ink and its influence on the print quality parameters.
