Claims (4)

  1. 刷装置によって描画される赤外マークであって、
    少なくとも高赤外吸収ガマットおよび低赤外吸収ガマットから導出されるカラー混合物と、
    前記カラー混合物を反するように構成された下地と、
    を備え、
    前記高赤外吸収ガマットおよび前記低赤外吸収ガマットは、境界により限定される類似の形状を有し、前記高赤外吸収ガマットおよび前記低赤外吸収ガマットは、各々、元の高赤外吸収ガマットおよび低赤外吸収ガマットの相関から由来し、前記カラー混合物は、前記高赤外吸収ガマットおよび前記低赤外吸収ガマットのうちのより下の方の端から生成された変換に由来し、
    前記高赤外吸収ガマットは、前記低赤外吸収ガマットに比べてカーボンブラックトナーの量を多く含む、
    赤外マーク。
  2. 赤外マークを画像上に作成するための方法であって、
    印刷するための入力画像を受け取り、
    高赤外吸収ガマットおよび低赤外吸収ガマットの相関効果をもたらす印刷ストラテジーを採用し、該相関効果は、前記高赤外吸収ガマットおよび前記低赤外吸収ガマットを、同一のガマット境界を有する同一の形状に変換し、
    前記印刷ストラテジーを使用して、赤外反射基板上に前記入力画像の印刷物を描画するため前記境界から生成された変換を使用し、赤外透かしを作成するために前記高赤外吸収ガマットおよび前記低赤外吸収ガマットが代替的に使用され、前記高赤外吸収ガマットの印刷物はブラックトナーの量が比較的多く、前記低赤外吸収ガマットの印刷物はブラックトナーの量が比較的少ない、
    ことを含む、方法。
  3. 前記印刷ストラテジーは、前記入力画像を、前記高赤外吸収ガマットおよび前記低赤外吸収ガマットの混合物に写像し、
    前記高赤外吸収ガマットの領域又は前記低赤外吸収ガマットの領域のうちの少なくとも一つは、他方から除外される、
    請求項2に記載の方法。
  4. 前記印刷ストラテジーは、前記入力画像を、前記高赤外吸収ガマットを前記低赤外吸収ガマットの形状に限定する前記低赤外吸収ガマットの境界に写像する、
    請求項2に記載の方法。
