Abstract
The invention provides a method of characterizing a scattering colored pigment for use in the determination of the absorption and scattering coefficients of the scattering colored pigment, the method comprising the step of obtaining a reflectance spectrum of a mixture of the scattering colored pigment with a substantially non-absorbing scattering pigment at a plurality of different volume fractions wherein the substantially non-absorbing scattering pigment has a particle size greater than 0.6 micron. Also provided is a pigment characterization system adapted to perform the method of the invention to characterize a scattering colored pigment.
