Description

本発明の目的を達成するために、例えば、本発明の印刷装置は以下の構成を有する。即ち、記録媒体上に印刷されたパッチの測色結果を、該パッチの温度を用いて補正する印刷装置であって、記録媒体上の印刷位置に印刷する印刷対象パッチについて予め求めた、該記録媒体の紙白温度に対する該印刷対象パッチの相対温度値を格納する手段と、前記印刷位置に対して前記印刷対象パッチを定着させる定着手段と、前記定着の後、前記印刷位置に定着させた印刷対象パッチを測色する測色手段と、前記記録媒体の紙白温度を測定する測定手段と、前記相対温度値と、前記測定手段が測定した紙白温度と、を用いて、前記印刷位置に定着させた印刷対象パッチの該測定した紙白温度を基準とする温度を、前記測色手段による前記印刷対象パッチの測色値を補正するために用いる温度として求める計算手段とを備えることを特徴とする。 In order to achieve the object of the present invention, for example, a printing apparatus of the present invention has the following configuration. That is, a printing apparatus that corrects a colorimetric result of a patch printed on a recording medium by using the temperature of the patch, the recording target obtained in advance for a printing target patch to be printed at a printing position on the recording medium. Means for storing a relative temperature value of the print target patch with respect to the paper white temperature of the medium; fixing means for fixing the print target patch to the print position; and printing fixed at the print position after the fixing Using the color measuring means for measuring the target patch, the measuring means for measuring the paper white temperature of the recording medium, the relative temperature value, and the paper white temperature measured by the measuring means, Calculating means for obtaining a temperature based on the measured paper white temperature of the fixed patch to be printed as a temperature used for correcting the colorimetric value of the patch to be printed by the colorimetric means. When That.

Claims
