Investigation of the effects of different ink density values on color gamut in offset printing

One of the most important reasons of increased print quality is the use of inks with a high coloring feature (Leach & Pierce, 1993). The film thickness of the ink should be below 2μm during printing (Dalton et al, 2002). The critical point is the direct effect of ink film thickness on print quality and color gamut. Ink absorption of paper and drying are the other important factors (Zjakić, Bates & Milković, 2011). It is also very important to have suitable solid ink density values for the used paper surface to achieve the desired print quality and color gamut. When the optimum amount of ink that is transferred onto the paper is set, the print quality as well as the color gamut will increase.
