Patent ID: 7333239

Claim:
A printing control apparatus that carries out printing with transmission of image data to a plurality of color printing devices, the plurality of color printing devices being capable of carrying out the printing upon input of image data expressed in a first color system and process of color conversion into image data expressed in a second color system, the printing control apparatus comprising: a specification module that specifies the color printing device among the plurality of color printing devices for carrying out the printing; a color conversion information setting module that sets color conversion information corresponding to the specified color printing device, the color conversion information defining the color conversion, wherein a group of color conversion information is defined in the format of a color conversion table that enables tone data in the first color system to be converted into tone data in the second color system, the color conversion information setting module including a color conversion information storage module that stores standard color conversion information used in common among the plurality of color printing devices and multiple sets of correction data for correcting the standard color conversion information, the multiple sets of correction data being preset to respective color printing devices, and a color conversion information generation module that generates the color conversion information, based on the standard color conversion information and the correction data corresponding to the specified color printing device; and a transmission module that transmits the image data and the color conversion information to the specified color printing device, wherein the multiple sets of the standard color conversion information are preset depending on the type of printing media, and wherein the color conversion information generation module generates the color conversion information using the correction data corresponding to the specified color printing device and the standard color conversion information corresponding to the type of printing medium that is selected by a user.
