An increasing number of color prints are now obtained from digital information with the hard copy being produced by ink jet, thermal dye transfer, and electrophotographic technologies. The permanence of these materials is of paramount concern. While there has been considerable investigation on the image stability of these materials, as it is affected by heat, humidity, light, and pollutants, there has been relatively little on their physical integrity. A physical property of primary interest is abrasion resistance. Damage to prints can occur when they are pulled from a stack or when they are accidentally subjected to rubbing action by other materials such as storage enclosures. This study was primarily concerned with the suitability of standard test methods for these materials. Abrasion resistance was evaluated using two standard abrasion tests; the Ugra Rub Test and the Sutherland® Rub Test. Experiments were made on ink jet prints on both swellable and microporous paper as well as on electrophotographic prints. The back side of one sheet of paper was rubbed against the image side of another, simulating a real-life situation. Additional abrading surfaces were a standard envelope paper, a smooth polyester sheet, and a relatively smooth abrasive cloth. Abrasion damage was determined by density change, by gloss change of a 1.0 density patch, by average grey levels, by delta E, and by the degree of smudging of colorants onto an adjacent Dmin area. These quantitative tests were compared to visual ratings. Both the Ugra and Sutherland tests produced similar abrasion actions, although the latter was more severe.
