Effect of Ink Formulation and Paper Surface Morphology on Ink-jet Printing Properties

The purpose of this study was to investigate the effect of different type of alcohols and humectants in inks formulation, as well as the influence of paper surface morphology on the ink-jet printing properties. In order to investigate the influence of alcohol and humectant types on printing properties, the optimum ink containing C.I. Reactive Blue 21 (Ink2) was formulated with different type of alcohols and humectants. The results of optical density and water fastness evaluations indicated that, the prints depend more on paper surface morphology rather than the type of alcohols and humectants in ink formulation. Optimum optical density and good water fastness properties were obtained on glossy coated ink-jet printed papers comprising optimum-diameter nano-porosities in their coating layer.
