Abstract: A method for generating a color space transformation table configured to convert an input color defined in a device-dependent color space of an imaging device into an output color defined in a device-independent color space is disclosed herein. The method comprises printing a plurality of sets of primary color targets using each of a corresponding plurality of primary colorants of the device-dependent color space. The primary color targets are printed by the imaging device at a selected number of coverage percentages. Target spectra of the primary color targets included within each of the plurality of sets of primary color targets are measured in order to create a plurality of initial spectra values. A plurality of additional spectra values corresponding to combinations of the primary color targets are then calculated. Each of these additional spectra values are based upon a combination of at least two of the initial spectra values.
