Claims (1)
- 色インクを用紙に吐出する色インクノズルおよび色インクとの間でにじみを生じる無色透明のクリアインクを用紙に吐出するクリアインクノズルを有する印刷部と、
前記クリアインクノズルの吐出検査の際、前記クリアインクノズルが吐出するクリアインクによるドットと前記色インクノズルが吐出する色インクによるドットとが、少なくとも一部が重なるようにクリアインクおよび色インクを用紙に吐出するよう前記印刷部を制御する印刷制御部と、
用紙上の色インクの広がり度合いに基づき、前記クリアインクノズルの不吐出の有無を判定する吐出判定部とを備え、
前記印刷部は、複数の前記色インクノズルがノズル配列方向に沿って配置された色インクノズル列と、前記色インクノズル列に並列して配置され、複数の前記クリアインクノズルが前記ノズル配列方向に沿って配置されたクリアインクノズル列とを有し、前記ノズル配列方向に直交する相対移動方向に沿って前記色インクノズル列および前記クリアインクノズル列に対して相対移動する用紙に色インクおよびクリアインクを吐出するものであり、
前記印刷制御部は、前記クリアインクノズルの吐出検査の際、隣接する前記クリアインクノズルが吐出するクリアインクによるドットが前記相対移動方向においてずれるとともに、前記相対移動方向における位置が同じで前記ノズル配列方向において隣接するクリアインクのドットどうしの中心間隔が所定画素数分以上となるパターンであって、クリアインクの各ドットに対して、少なくとも一部が重なる色インクのドットを形成するパターンを印刷するよう前記印刷部を制御することを特徴とするインクジェット印刷装置。
