Sažetak
This paper deals with color reproduction and differences and print quality elements of ink-jet prints on plain office paper. The printing technique used was drop-on-demand thermal ink jet. Samples were printed on HP DeskJet 5150 printer with default ink types, CMY ink being dye and Black ink being pigment type. Same ink settings were used for all the paper types, which assured that the same volume of ink was transferred on every sample. Papers chosen were all plain uncoated office papers of various quality grades. The printed images consisted of GretagMacbeth ColorChecker® ; simulated charts and ECI Target Visual Layout test forms. General, surface and optical paper characteristics were measured for the purpose of evaluating their effect on the color reproduction and the print quality elements. Color reproduction characteristics and Δ E differences, as well as print quality elements of samples were measured with spectrophotometer and densitometer respectively. All the fields of Gretag Macbeth ColorChecker® ; were measured and their L*a*b* and Δ E values were evaluated. Density and Dot Area fields (for cyan, magenta, yellow and black) of ECI Target Visual Layout were measured and reproduction curves were plotted. Print quality elements, such as Tonal Value Increase and Print Contrast were also calculated. The obtained spectrophotometric and densitometric values were correlated to the paper characteristics.
