In order to obtain a desired print result, a color correction process may be performed on image data based on the characteristics of a printing device. Data called target profile (TP data) showing the characteristics of the printing device is used for the color correction process. When a user makes a request to an image processing device for image processing, it is judged whether TP data is required for the image processing or not. When TP data is required, image processing using the TP data is executed. Further, the fee for use of the TP data and the fee for the image processing are charged on the user of the requester.
