Abstract

Kubelka and Munk absorption and scattering coefficients for a nonwhite pigment dispersion (tinter) can be obtained from reflectance measurements on opaque samples of a reference white base and two tinter/white mixtures. The precision of the coefficients depends on the strengths of the mixtures, and the conditions for maximum precision have been determined from a theoretical analysis of the errors caused by a constant error in the measurement of absolute reflectance. One sample should consist of tinter without admixture of white, while the other should have reflectances as far as possible between 25% and 75% throughout the spectral range of interest.
