Zusammenfassung:To provide registration system, method and program in a printer which can suppress occurrence of color tone failure due to doubling at the registration time.SOLUTION: A registration system is provided with a plurality of printing units which performs printing of a plurality of different colors including a reference color on a printing object, and each of the plurality of printing units comprises a plate cylinder. The system comprises: positional deviation amount acquisition means 13 which acquires a positional deviation amount of a printed image of other color with respect to a printed image of the reference color printed on the printing object by the plurality of printing units; and plate cylinder moving means 15 which moves a plate cylinder of a positionally deviated color of the plurality of plate cylinders in order to eliminate the positional deviation amount acquired by the positional deviation amount acquisition means 13. The plate cylinder moving means moves the plate cylinder so as to execute movement of the printed image for eliminating the positional deviation amount while dividing the movement into multiple movements with a movement amount smaller than the positional deviation amount.SELECTED DRAWING: Figure 2 【課題】見当合わせ時にダブリによる色調不良が発生することを抑制できる印刷機における見当合わせシステム及び方法並びにプログラムを提供する。【解決手段】基準色を含む複数の異なる色の印刷を印刷対象物に印刷する複数の印刷ユニットが設けられ、複数の印刷ユニットのそれぞれは、版胴を備え、複数の印刷ユニットにより印刷対象物に印刷された基準色の印刷画像に対する他の色の印刷画像の位置ずれ量を取得する位置ずれ量取得手段13と、位置ずれ量取得手段13により取得した位置ずれ量を解消するために複数の版胴のうちの位置ずれしている色の版胴を移動させる版胴移動手段15と、を備え、版胴移動手段は、位置ずれ量を解消するための印刷画像の移動を位置ずれ量よりも小さい移動量での複数回の移動に分けて実行させるべく、版胴を移動させる。【選択図】 図2
