Abstract
A computer product for controlling a color-reproduction process employing N colorants, where N is greater than 3, the computer program product comprises: a computer readable storage medium having a computer program stored thereon for performing the steps of: defining a first transformation from a N-dimensional colorant-signal space associated with the color-reproduction process to a 3-dimensional colorimetric space such that each combination of N colorant signals is mapped to a visual color that would be produced by the process in response to that combination of signals; defining a second transformation for mapping from a 3-dimensional parameter space into the N-dimensional colorant-signal space for defining a particular 3-dimensional subspace of the N dimensional colorant-signal space for ultimately restricting the permitted combinations of the N colorant signals; combining the first and second transformations for defining a third transformation for transforming data directly from the 3-dimensional parameter space to the 3-dimensional calorimetric space; finding the mathematical inverse of the third transformation for defining an inverse transformation which transforms data from the 3-dimensional calorimetric color space to the 3-dimensional parameter space.
