  • Patent number: 6636315
    Abstract: The quality of distribution of pigments in a matrix is estimated by measuring the reflectivity of a sample of the pigmented matrix at a shorter and a longer wavelength, and calculating a function of the two measurements. A ratio of the normalized reflectivity for broad short and long wavelength bands is the preferred function.
