Roughness of a variety of commercial ink jet papers was tested by Parker Print Surf (PPS), EMVECO stylus profilometer and Atomic Force Microscopy (AFM). The papers were printed on three Epson ink jet printers. Correlations between roughness and paper or print gloss were studied. From all three roughness-testing methods used, the best correlation was found for AFM. Topography of ink film was also studied by AFM.
