Abstract:
1. A method of correcting the color of a print medium, comprising the steps of: converting device-dependent image data to first colorimetric data with color converting means given to a standard print medium; thereafter, converting said first colorimetric data to second colorimetric data with color correcting means to correct the difference between the color of a desired print medium and the color of said standard print medium; and producing a proof on which the difference between the color of said desired print medium and the color of said standard print medium has been corrected, on a proof medium with an image output device based on said second colorimetric data; wherein said color correcting means comprises one-dimensional lookup tables for converting said first colorimetric data to said second colorimetric data, wherein the converting of the first colorimetric data to second colorimetric data includes a direct conversion between the first and second colorimetric data, and wherein each of the first and second colorimetric data each comprise device-independent color spaces.
