Abstract

In this study, ink-jet prints obtained on two Epson L805 printers and Canon PIXMA G2411 MFPs were analyzed. The relevance of this work is due to the need to understand how different classes of office paper affect print quality, especially in conditions when the requirements for printed materials are becoming more and more high. In the context of growing competition in the printing services market, as well as increasing user needs for high-quality printing, it is important not only to choose the right printer, but also to choose the right paper that will meet the specifics of printing. In this regard, research on the impact of paper irregularity on print quality is becoming an important task, contributing to the optimization of printing processes and increasing user satisfaction. The study assessed the impact of paper heterogeneity on print quality using a densitometer. Optical density measured with X-Rite densitometer was chosen as one of the indicators of printed matter quality. Densitometric control of the quality of color printing is carried out indirectly through the measurement of the optical density of primary color dies. This method is fast, technological and does not require large costs and qualified specialists. Print quality was evaluated using cyan (C), magenta (M), yellow (Y) and black (K) plates. The image saturation of different paper samples was evaluated by comparing the optical density of the color dies. Analyzing the obtained data, it can be noted that the optical density values, which indirectly reflect the thickness of the ink layer on the impression, differ depending on the class of paper, as well as the structural heterogeneity of the sealed material.
