Abstract
We propose a method that uses the point spread function of specular reflection(SR-PSF)
to simulate paper gloss. The SR-PSF is defined as the impulse response
of specular reflection, which is the distribution of light intensity reflected
from microscopic facets on the surface of the paper. In this study, we
used a flat sample holder and measured the SR-PSFs of six paper samples,
each of which had a different level of specular gloss. We then used two
different methods based on the measured SR-PSFs to simulate the gloss of
curved paper. The results show that the gloss of curved paper can be adequately
simulated by using the measured SR-PSF of that paper.
