Patent ID: 8861037

Claim:
A total color material amount restriction profile creation method used in image signal processing which creates an image signal supplied to an image formation apparatus and which includes color management system processing using a common printer profile and total color material amount restriction processing using a total color material amount restriction profile after the color management system processing, the method comprising: a step of acquiring a first total color material amount restriction profile that defines a correspondence relationship between color data prior to total color material amount restriction processing before the total color material amount restriction processing used in the color management system processing is implemented, and color data subjected to total color material amount restriction processing which is acquired by the total color material amount restriction processing, under a first configuration condition of the image formation apparatus; a step of acquiring a first color predictor that defines a correspondence relationship between the color data subjected to total color material amount restriction processing and an output color output from the image formation apparatus, under the first configuration condition of the image formation apparatus; a step of acquiring a second color predictor that defines a correspondence relationship between color data based on an image signal input to the image formation apparatus and an output color output from the image formation apparatus, under a second configuration condition of the image formation apparatus; a step of searching and acquiring, through the second color predictor, color data under the second configuration condition corresponding to an output color that matches or approximates an output color which is acquired through the first color predictor from the color data subjected to total color material amount restriction processing which is acquired by the total color material amount restriction processing using the first total color material amount restriction profile; and a step of associating the color data searched and acquired under the second configuration condition and the color data prior to total color material amount restriction processing and creating a second total color material amount restriction profile.
