A Re-evaluation of Factors Controlling Print Rub on Matt and Silk Coated Papers (Part 1)

摘要

Print rub, or ink scuff, remains one of the greatest challenges for the successful development of matt and silk matt offset coated papers. Using a recently proposed method for evaluating print rub, involving a non-slip pressure and friction induced stress contact between a printed and unprinted sheet, this feature seeks to test the hypothesis that the ability to improve print rub resistance is a function of coating surface capillarity (absorption) and adsorption properties, in combination with the roughness and compressibility/conformability of the basepaper-coating composite on the fibre-floc scale.
