If hiding computations are to be made in conjunction with computer color matching, the Kubelka–Munk absorption and scattering coefficients, K and S, must be dimensioned (absolute) coefficients. Two procedures for calculating the dimensioned coefficients were compared. In the first, the coefficients were calculated directly by two different methods from films applied at incomplete hiding over white and black substrates. In the second, previously calculated dimensioned coefficients for titanium dioxide formed the basis of determining the coefficients for the remaining pigments from films applied at complete hiding. Experimental results showed the second procedure superior to either method of the first procedure, except for determining dimensioned K and S for titanium dioxide.
