Abstract
In this paper, we extend the data analysis of gloss from prints making use of the visibility concept for the signal of a diffractive optical element based glossmeter. It is shown that the visibility is sensitive to the borders of the prints on uncoated paper. We suggest that the gloss map is due to the simultaneous dependence on both the refractive index and the surface roughness of the print, whereas the visibility is independent of the refractive index, and hence is sensitive only to the surface roughness. The visibility map and relevant statistical parameters provide new means to inspect prints on paper and other substances.
