Criterion Evaluation of Qualitative Characteristics of the Contemporary Offset Printing

In this work researches had been made on color measurement patches of color control bar from the test form that was printed on waterless and conventional offset printing presses. The prints were printed with waterless and conventional offset printing technology on four widely used printing substrates which are: glossy fine art paper, matt fine art paper, coated woodfree paper and uncoated woodfree paper. The measurements on the prints were made with densitometer and results from objective research regarding to area coverage (tone value) in conventional and waterless offset printing are presented in tables. Marginal prints printed by International standards from both conventional and waterless offset printing were distinguished based on the results that came from researches. Print reproduction curves for colors that are used in multicolor offset printing were made based on the measured results of research for both conventional and waterless offset printing. Realistic print reproduction curves for prints made in conventional and waterless offset printing are shown in figures based on the area coverage (tone value) measurements. Ratios in area coverage (tone value) and ratios in realistic print reproduction curves were established based on the results that came out of the measured prints made on conventional and waterless offset printing presses on different printing substrates, and the suggestion is given for optimization in multicolor printing reproduction.
