Thermal Load Effect on Print Quality of Ink Jet Printined Textile Materials

Abstract

Printed textile materials are often exposed to certain external impacts. One of the most common impact, these materials are subjected to, is thermal load. This effect causes certain changes in textile fibers as well as changes of ink colour reproduction printed on these materials. In this paper is presented an investigation of the series of thermal loads effects on print quality parameters of digitally produced impressions on textile substrates. The research includes basic print quality attributes: colour reproduction, macro non-uniformity and quality of line reproduction. Investigation results indicate that by increasing number of thermal loads, bigger changes in colour reproduction occur. Also, the influence of the series of thermal loads on mottle and line reproduction variations is confirmed, as well as the influence of printing substrate characteristics on print quality.
