Non-destructive methods in the study of IJ ink – substrate interaction

The quality of ink-jet prints depends to a large degree on the interaction between printing substrate and Ink-Jet ink. The penetration of printing ink should be low in order to retain high optical colour density. The surface of the paper also plays an important role: the absorption capacity for printing inks should be controlled. It should not dust and should have a suitable level of smoothness as well as other properties necessary for good operability and printability. The scope of the study was to find non-destructive methods that can give a rapid and accurate insight into the Ink-Jet ink penetration in z-direction of the substrate. The aim of the study was to investigate the radial and vertical distribution of Ink-Jet printing ink, both on and beneath the paper surface, on different types of papers, as well as to determine the impact of the paper surface on print quality.
