Nominal Scaling of Print Substrates

Print substrates are often measured or characterized using optical measurements, such as spectra or colorimetric measurements. Specialized devices or techniques exist to measure other properties, such as thickness, surface roughness, fluorescence, opacity or gloss. However, these measurements are often disjoint and, with respect to color imaging requirements, they are often a secondary consideration. We present specific measurement data for a collection of digital commercial print substrates and explore the correlations of these measures and their general distributions. We then present the results of a nominal scaling experiment in which both the visual and tactile properties of 72 print substrates was evaluated by 21 subjects. These evaluations were based on unconstrained text descriptions of the samples. The analysis made use of techniques from corpus linguistics to determine multivariate clustering by keywords and by samples. This allows both a global view of the visual and tactile categorization schemes of the subjects, as well as specific pairing of print substrates deemed to be most similar by subjects. We conclude with a discussion of nominal scaling and it's relevance to perceptual categorization.
