Abstract
The present invention provides a color conversion apparatus that converts image data for a printing press into image data for a printer. The apparatus includes: a first spot color conversion processing section that converts a spot color name into a L*a*b* value by referring to a L*a*b* separation spot color table in which spot colors are associated with L*a*b* values and converts the obtained L*a*b* value into process colors of ink colors for a printer by referring a printer profile; and a second spot color conversion processing section that converts a spot color name into ink color data for the printer by referring to an N-color separation table in which spot color names are associated with ink colors for the printer. The apparatus uses either one of these sections by switching from one to the other, or uses both the sections according to priority.
