Effect of Substrate and Ink Formulation on Printed Color Gamut

The goal of this work was to gain a fundamental understanding of how the structural and optical properties of the coated substrate and the printing ink formulation impact the color gamut of the final printed matter. The collected data suggests that the main influences on printed color gamut are from coated paper whiteness, coating pore volume, and the ink used during printing. Each of the coating properties are in turn influenced by the coating materials used, and whether those materials create changes in the coating structure or the final color tone of the coated paper. Secondly the ink formulation, and mainly the relationship between the ink vehicle, resins and other ink components, influences the ink setting and final print quality. This paper will take a more focused look into the mechanics behind color gamut by attempting to isolate the different components that affect the final color gamut volume. The main goal is to quantify the impact each of these has on the final printed color gamut.
