The aim of this experiment was to explore the perception of tactile surface-feel of 21 printing papers. A multidimensional scaling (MDS) experiment was conducted with 20 women. They scaled similarity among all possible pairs of the papers. Similarity measurements were mapped by INDSCAL and modeled with PREFMAP. Test-retest and concordance coefficients were high. It is not yet established what physical properties best determine tactile feel. It seems likely though that finger friction and surface roughness are strong contenders. Finger friction for the papers was measured as a ratio of friction force to normal force;(while stroking a human finger on the surface. Average surface roughness was measured with a profilometer. Physical properties were rotated into the 3D INDSCAL solution. This solution identified and mapped the tactile surface feel of the papers in an interpretable way with regard to i.e. friction, surface roughness and weight.
