Claim One:
1. A method of providing at least one optical property of a coating system having a coating adjacent a base sheet comprising: a) providing a radiative transfer equation that relates a number of physical characteristics of the coating system selected from the group consisting of coating thickness, coating pore size distribution, coating pigment particle size, a coating pigment particle size distribution, a coating roughness, scattering coefficient, absorption coefficient, anisotropy factor, and optical properties of a base sheet to one or more optical properties for a coating system selected from the group consisting of gloss, brightness, and opacity; b) solving the equation by inputting a number of the physical characteristics of the coating system to obtain at least one optical property output of the coating system; and c) formulating a pigment coating including the obtained at least one optical property output.
