Patent ID: 7933042

Claim:
An image document creation apparatus provided so as to be connectable to a plurality of image forming apparatuses that have been arranged on a network, the image document creation apparatus comprising: a color gamut information acquisition unit that acquires color gamut information possessed by the image forming apparatuses; an identification unit that identifies input colors included in document data and/or image data saved in the image document creation apparatus; a color difference calculation unit that performs, for each of the image forming apparatuses, processing to obtain a color difference sum and a color difference maximum value by calculating a color difference between the input colors identified by the identification unit and the color gamut information acquired by the color gamut information acquisition unit, and processing to obtain a color difference average value based on the obtained color difference sum and the number of input colors; an apparatus selection unit that selects an image forming apparatus as a print target based on the color difference average value obtained by the color difference calculation unit; a printing unit that instructs the selected image forming apparatus to print the document data and/or the image data; a color difference table in which color difference perception messages corresponding to a plurality of color differences have been registered in advance; and a showing unit comparing, respectively to the color difference table, the color difference average value and the color difference maximum value obtained with the color difference calculation unit relative to the image forming apparatus as the print target selected by the apparatus selection unit, extracting the color difference perception messages that corresponds to the color difference average value and the color difference perception messages that corresponds to the color difference maximum value from the color difference table, and showing each extracted color difference perception message.
