Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a color chart creation method for creating a color chart of a wider color range, and a color correction method.SOLUTION: In image data for printing a color chart by a printer, the restriction of ink amount to be fed to a printing medium is performed not in a TAC value or the total amount of CMYK values to be given to one pixel but is adjusted in consideration of an ink amount per unit area to be actually consumed at a printing time and the dehydration performance of each ink, so that a color chart of a wide color range can be created.SELECTED DRAWING: Figure 4 【課題】インクジェットプリンタにおける、より色域の広いカラーチャートを作成するカラーチャート作成方法および色補正方法を提供する。【解決手段】カラーチャートを印刷機により印刷するための画像データにおいて、従来のように、印刷媒体に供給するインク量の制限を、１画素に与えるＣＭＹＫ値の合計であるＴＡＣ値で行うのではなく、印刷時に実際に消費される単位面積あたりのインク量と各インクの乾燥性能を考慮して調整することで、色域の広いカラーチャートの作成を可能にする。【選択図】図４
