an algorithm for color matching of textiles with elimination of limitation on primaries

the proposed algorithm suggests a new method for determination of k/s value of primaries based on linear least squares technique. by applying the matrix pseudoinverse, a modification is introduced to eliminate the limitation on the numbers of applied dyes in one – constant kubelka-munk theory. the selection of dyes for tristimulus matching are also done on the basis of the initial spectrophotometric results. the applicability of suggested methods are tested through a computer colour matching attempt with more/less than three primaries.
