Abstract

　１枚の印刷文書において、埋め込まれた情報の読み取り、偽造及び改竄の検出の機能、並びに複写の牽制の機能が充分に発揮にされるようにする。牽制デザイン１１により定められたデザインから、所定の位置、大きさ、色を有する牽制点からなる牽制画像１３を生成する。一方、文書付地紋透かし画像１２から、一部の地紋点を除去した除去後地紋透かし画像１４を生成する。この牽制画像１３と除去後地紋透かし画像１４を合成して合成画像１５を生成する。合成画像１５として出力された印刷文書は、地紋透かしの効果及び牽制の効果の両効果が互いに干渉することなく、埋め込まれた情報の読み取り、偽造及び改竄の検出の機能、並びに複写の牽制の機能が充分に発揮にされた非常にセキュリティの高い印刷文書である。
