Patent ID: 8174730

Claim:
A printing control device which designates a color material amount set, which is a combination of use amounts of plural color materials, to a printing apparatus and performs printing on the basis of the color material amount set, when permitting the printing apparatus to perform the printing by attaching the plural color materials to a print medium, the printing control device comprising: a target spectral reflectivity acquiring unit which acquires spectral reflectivity of a target as an acquired target spectral reflectivity; and a printing control unit which acquires a color material amount set corresponding to the acquired target spectral reflectivity with reference to a lookup table, the lookup table defining a correspondence relation between a plurality of color material amount sets and a plurality of target spectral reflectivities, and which designates the acquired color material amount set to the printing apparatus to perform the printing, wherein in the lookup table, a correspondence relation between a particular color material amount set and a particular target spectral reflectivity is defined based on a degree of approximation between the particular target spectral reflectivity and the spectral reflectivity reproduced on the print medium when the particular color material amount set is designated to the printing apparatus to perform the printing, said degree of approximation being adjusted by a wavelength-dependent weighting.
