Sažetak
This paper studies the influence of substrate roughness and thickness on the print quality in electrophotography. Mechanical dot gain in the printing process and the impact on the gloss change as a function of ink applied to various substrates were investigated. Printing on a digital printing machine HP Indigo 4500 was performed on three types of surfaces: Paper Fasson White Top Indi Centaure ALF606 S2030 weight 93 g/m2, Polypropylene Digit Fasson PP Top White Indi 300 ALA S692N weight 58 g/m2, and coated Fasson Digit Indi MP Gold Top S2000N weight 60 g/m2. The dot gain measurements were carried out in the fields of 20 %, 40 %, 60 % and 80 % of black ink, and the data were analyzed using ImageJ software. The measurement of gloss was performed using a Gloss Master device, in the same fields of 20 %, 40 %, 60 %, 80 % and additionally in full-tone (100 %) for the four process colors (CMYK). Roughness and thickness measurements of the printed substrates were carried out to determine the impact of these parameters on the gloss.
