A generally applicable theoretical model describing light propagating through turbid media is proposed. The theory is a generalization of the revised Kubelka–Munk theory, extending its applicability to accommodate a wider range of absorption influences. A general expression for a factor taking into account the effect of scattering on the total photon path traversed in a turbid medium is derived. The extended model is applied to systems of ink-dyed paper sheets—mixtures of wood fibers with dyes—which represent examples of systems that have thus far eluded the original Kubelka–Munk model. The results of simulations of the spectral dependence of Kubelka–Munk coefficients of absorption and scattering show that they compare very well with those derived from experimental results.
