<p>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 (422) in order to create a plurality of initial spectra values (424). 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. The initial spectra values and the additional spectra values are transformed into a set of device independent color values defined in the device-independent color space. Finally, the device-independent color values are inserted into a color table arranged so as to establish a correspondence between ones of the device-independent color values and device- dependent color values defined with respect to the device-dependent color space (520).</p> |
