Gloss has been estimated by the numerical value of the traditional glossmeter, but it is not necessarily in agreement with subjective assessment. The subjective evaluation of gloss is presumed to be related to reflected light intensity and the distribution around the specular direction. We simulate specular reflected light intensity distribution by measuring the surface shapes and optical properties of sample papers. We then conduct a comparative study of the simulation results and the measured distribution.
