Paper Abstract
Angle-resolved light scattering (ARLS) was used to investigate the roughness of
coatings on glossy paper. Angular spectra were measured for laser light scattered
from several glossy paper samples and from uncoated paper. These spectra are compared
to those calculated using the Beckmann model of a random surface that is isotropic
and rough in two dimensions. Such a surface is characterized by its rms
roughness and autocorrelation function, which are determined from surface profiles
measured with a stylus instrument. There is very good agreement between the measured
and the computed ARLS spectra. The surfaces are too rough to produce a specular
beam large enough to provide an accurate value of the rms roughness, but ARLS
provides information about the coating roughness when the measured spectra are cornpared
to computed ones.
