摘要： A color prediction system includes: database storing absorption/scattering coefficients of each primary color ink; sections for: selecting a spot color ink as a combination of primary color inks that reproduce a colorimetric value of a color sample, reading absorption and scattering coefficients of the primary color inks of a reference spot color from the database, obtaining absorption and scattering coefficients of the spot color ink of a specified formulation ratio, and calculating a spectral reflectance of the spot color ink to be reproduced; obtaining a reproduced color from the spectral reflectance; obtaining a difference from the colorimetric value of the color sample and correcting the formulation ratio to calculate a formulation ratio with an allowable difference; and calculating a Neugebauer primary color of overprinted spot color inks from the absorption and scattering coefficients of the spot color inks calculated at formulation ratios determined by the formulation ratio determination section.
