GAMUT SHAPE PREDICTION METHOD, GAMUT SHAPE PREDICTION PROGRAM, AND PRINTING APPARATUS LOADED WITH COLOR CONVERSION TABLE GENERATED USING GAMUT PREDICTED BY GAMUT SHAPE PREDICTION METHOD

摘要

A gamut shape prediction method of predicting a shape of a gamut expressed on a predetermined color space for an output apparatus includes: forming a plurality of target data which represents a cross-section surface along a first axis in the predetermined color space where the gamut is formed and which is used to search for boundary points of the gamut; calculating the boundary points of the target data by setting all boundary points of the target data located above or below along the first axis as references; and predicting the shape of the gamut from the calculated boundary points of each target data.
