Influence of substrate roughness on print quality parameters of digitally printed paper substrates
In addition to printing techniques, there are various characteristics that affect the quality of printed products. Most frequently questioned features are line, dot, and text reproduction. In this paper it is investigated how different substrates, printed by the same printing technique, affect the quality parameters of printed samples. Print quality includes the process of obtaining the desired reproductions of color and image elements, important parameters of print quality are the quality of lines and dots, and the feature of the substrate that is significant for this work is the roughness of the substrate. This paper presents the testing of three different materials on to which the test form was printed by electrophotography, as a digital printing technique. The tests are based on analysis of line, dot and text reproduction, as well as analysis of the roughness of the substrate on samples printed in black. Based on the obtained results it can be concluded that the substrate affects the quality of printed products.
