Surface energy⁽¹⁾ of a substrate plays a vital role in determination of surface characteristics in terms of interactions with liquid phases, such as inks. The polar and dispersive components of surface energy are employed so as to estimate the interaction of a substrate with polar and non-polar liquids.

This study involves the determination of the dependence of surface energy of coated paper on various calendering conditions and effect of post-calendering environmental conditions, such as relative humidity, on surface energy. This is of great importance in estimation of ink-substrate interactions and associated print attributes.
