Roughening Due to Ink Jet Rewetting: Effect of Paper Treatment and Composition
  DOI :  10.2352/J.ImagingSci.Technol.(2008)52:1(010506)  Published OnlineJanuary 2008

An ink jet printer was used to deliver small quantities of ink-dyed water to laboratory 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, it was found that the relative change in local roughness after rewetting (change in roughness divided by initial roughness, ΔRa/Rao) increased with the degree of calendering, beating, and the amount of surface and internal sizing. The corresponding changes in skewness and kurtosis after rewetting reflected the development of increased fiber rising. Increasing amounts of surface sizing produced larger ΔRa/Rao, corresponding to an increase in the ink penetration depth. Rewetting produced the greatest ΔRa/Rao in paper manufactured with mechanical pulp, with ΔRa/Rao becoming smaller as the fraction of chemical pulp was increased to 0.4, after which it became insensitive to composition.
