Hot melt/phase-change or solid inks differ with other digital and conventional inks in terms of properties and mechanisms of transfer onto a substrate, therefore there exists a need for developing low cost substrates compatible with these solid inks in terms of surface properties and print attribute standards.

These inks solidify immediately upon contact with the substrate which results in very little absorption of the ink into the substrate or its coating, hence, some substrates perform better with these inks in terms of print quality and ink adhesion. Thus, it is important to understand the controlling mechanisms governing surface properties of substrate so as to find the best low cost solution to printing with digital solid ink printers.

Economics also play a vital role as the paper specially formulated for digital printing with phase-change inks are an order of magnitude being more expensive, so there is a need for the development of lower cost substrates compatible with solid inks so as to achieve high print quality at a reduced price.
