Description: An inkjet printer was used to deliver small quantities of ink-dyed water to commercial paper and handsheets having a range of compositions and treatments. An optical profilometer recorded initial and final roughness statistics at fixed locations on the printed surfaces. For paper made with chemical pulp, the relative change in local roughness increased with the degree of supercalendering, beating and sizing. The changes in skewness and kurtosis reflected the development of increased fibre rising, so that surfaces contained a greater fraction of "peaks", and a broadening of the distribution of profile heights as the microtopography became more random. The increased relative roughening of paper with the amount of surface sizing corresponded to an increase in the ink penetration depth. Relative roughening was greatest with paper manufactured with mechanical pulp, and became smaller as the fraction of chemical pulp was increased to 0.4, after which it became insensitive to composition.
