Description
<インクジェット印刷装置の全体構成>
本発明の実施例1では、用紙の搬送方向と直交する方向(主走査方向)に配列されたインクジェットヘッドを有し、搬送経路上で搬送された用紙に対して、画像データに基づいてインクジェットヘッドのノズルからインクを吐出して印刷するライン型のインクジェット印刷装置を例に挙げて説明する。
次に、本発明の実施例1であるインクジェット印刷装置1の機能構成について説明する。
次に、影響度算出部81aは、ステップS180において算出された影響度Eが、影響度閾値Eth以上か否かを判定する(S190)。
本発明の実施例1では、取得したギャップ影響度Egと、温度影響度Etと、画像位置影響度Elとに基づいて、影響度Eを算出するインクジェット印刷装置1を例に挙げて説明した。
図14は、本発明の実施例2であるインクジェット印刷装置1のCPU81により算出された影響度Eの算出例を示した図である。
