Abstract
A system and method can generate a singular solution where a color is represented by an unique set of values in a first color space corresponding to more than one set of values which represent the same color in a second color space. One preferred method determines a singular set of colorant values from an N dimensional system for a given set of values from an N minus M dimensional system, 1.ltoreq.M<N, where a function which describes a transformation from the N dimensional system to the N minus M dimensional system is predefined, and the method includes the steps of: defining a first predetermined error function based on the N minus M dimensional system; defining a second predetermined error function based on the N dimensional system; defining one of the error functions as a primary error function and the other as a secondary error function by applying predetermined weighting functions thereto; combining the primary and secondary error functions; and determining a set of values from the N dimensional system by minimizing the combined error functions.
