COMPARATIVE ANALYSIS OF THE QUALITY OF FEATURES PROVIDED BY THE ELECTROPHOTGRAPHIC PROCESS AT KUNSTDRUCK PAPERS

Abstract

The paper presents research in the field of digital technique of press-electrophotography. For prin- ting, the Konica Minolta Bizhub C220, Konica Minolta Bizhub PRO C1060L and Xerox Versant 80 Press graphic system were used. For the purposes of this research, a test card was created, which was printed on three sub- strates of different grammes of 100 g/m², 250 g/m² and 300 g/m², followed by optical densities, increase in tonal values, CIE Lab values, spectral field reflection on the test map and white and yellow paper measurements. The results of the work are shown using graphics, followed by analyzing and comparing the results obtained. The aim of the study is to calculate the color difference, the analysis of which later determined the quality of print reprodu- cibility in different time intervals.
