Abstract

A client controls printing of color chips (images for colorimetry) with a plurality of tones for individual color inks (printing colorants). The client acquires from a server a tone value correction table (color matching information) to match standard colors. The server can acquire the lightness data of color chips for individual inks and create the tone value correction table based on the lightness data of color chips of individual color inks and the lightness data of standard colors corresponding to the color inks, and subsequently send the color matching information to the client. As a result, it is easier to produce colors that match standard colors.
