16 Claims

13. A color image forming system which comprises a color image forming apparatus capable of using a PDL (page description language) on a network, and at least one client computer connected to the network, said color image forming apparatus preparing an image for outputting by means of a printer,

wherein said color image forming apparatus comprises:

means for outputting image data;

means for analyzing a specific PDL and converting the analyzed specific PDL into a raster image;

means for analyzing a content of a specific color profile and converting the image according to the analyzed content;

means for administrating a list table of at least one color profile; and

means for holding data of the color profile,

wherein said list table consists of information functioning as a key for retrieving the specific color profile and a real data portion of the profile, and

wherein said client computer comprises:

means for displaying to a user a list of profiles available on the client computer;

means for converting a graphic language on the client computer into the specific PDL;

means for administrating a list table of at least one color profile; and

means for holding data of the color profile,

wherein said list table consists of information functioning as a key for retrieving the specific color profile and a real data portion of the profile, and

wherein said color image forming system further comprises:

means for comparing the color profile of said client computer and the color profile in said color image forming apparatus with each other on the basis of specific key information, said comparison means performing the comparison of the color profiles at arbitrary timing;

means for registering the color profile in said color image forming apparatus at arbitrary timing in a case where it is found based on the result of the comparison that color profile information of said client computer and color profile real data are non-existent in said color image forming apparatus;

means for generating a specific PDL operator to designate the color profile in a PDL code based on a specific key code, in accordance with the result of the comparison by said comparison means;

means for adding a respective printer identifier of each of one or more printers connected to the color image forming apparatus on which the predetermined profile has been registered, to a registration destination printer list to be used in judging whether the predetermined profile in the client computer is registered in each of the printers; and

means for incrementing the total number of the registered-destination printers for the registered profile.
