To provide for achieving color stability with better accuracy.SOLUTION: An area, in which a prescribed number of recording materials is used in a read image, which is obtained in such a manner that an acquisition part reads a recording medium on which a printing part has printed by use of a plurality of recording materials, is so made as to be a reference area. Correction information is created for the recording material, which has not yet created correction information for reducing density change in printing by the printing part, of the recording materials used in the reference area. A printing image, which is printed by the printing part, is corrected by use of the created correction information. The afore-said creation is performed for each read image, and the prescribed number is increased at each time of performing the creation.SELECTED DRAWING: Figure 1 【課題】 より精度良く色安定を図るための技術を提供すること。【解決手段】 印刷部が複数の記録材を用いて印刷を行った記録媒体を取得部が読み取ることで得られる読み取り画像において所定数の記録材が用いられている領域を参照領域とする。そして、該参照領域に用いられている記録材のうち、印刷部による印刷における濃度変化を低減させるための補正情報を未だ作成していない記録材について補正情報を作成する。該作成した補正情報を用いて、印刷部が印刷する印刷画像を補正する。読み取り画像ごとに上記の作成を行い、該作成を行うたびに所定数を増加させる。【選択図】 図１
