Description
本発明によれば、原稿画像データと目標印刷物に基づいて、目標プロファイルとしての色変換テーブル（第２の色変換テーブル）を作成することができる。本発明によれば、目標プロファイルの色変換テーブルを作成するにあたり、印刷装置による印刷物の出力とその印刷物の読み取り作業を省略することができ、色合わせ作業を簡易化できる。 According to the present invention, on the basis of the original image data and the target printed matter, it is possible to create a color conversion table as a target profile (second color conversion table). According to the present invention, when creating the color conversion table of the target profile, the output of the printed material by the printing apparatus and the reading operation of the printed material can be omitted, and the color matching operation can be simplified.
また、本発明によれば、原稿画像データの色空間（第３の色空間）とデバイス非依存色空間（第２の色空間）との多次元の対応関係を表す色変換テーブル（第２の色変換テーブル）を作成するため、従来の一次元の対応関係で色調整を行う場合と比較して、より高精度な色合わせが可能となる。 Further, according to the present invention, the color conversion table (the second color space) representing the multidimensional correspondence relationship between the color space (third color space) of the document image data and the device-independent color space (second color space). Since the color conversion table is created, more accurate color matching is possible compared to the case where color adjustment is performed using a conventional one-dimensional correspondence.
従来の印刷システムの場合、このような色変換テーブルを作成する際は、一般に、カラーチャートを用いて、色空間全体に規則的に配置された画像信号値と色度値との対応関係を求め、この対応関係から所定の補間方法で補間して色変換テーブルを作成する。 In the case of a conventional printing system, when creating such a color conversion table, generally, the correspondence between image signal values and chromaticity values regularly arranged in the entire color space is obtained using a color chart. From this correspondence, a color conversion table is created by interpolation using a predetermined interpolation method.
ＩＤ＝２〜５については、直接的に対応する格子点がないため、近隣の格子点に対して色度値を設定する。図１１に示すように、ＩＤ＝２，３，４について、原稿画像信号値を取り囲む周囲４つの格子点に色度値を設定する。 For ID = 2 to 5, because there is no lattice points corresponding directly, with respect to neighboring lattice points set the chromaticity values. As shown in FIG. 11, for ID = 2, 3, and 4, chromaticity values are set at the four surrounding grid points surrounding the document image signal value.
