Description
<描画部>
描画部60は、媒体100の描画面にシアン、マゼンタ、イエロー、及びブラックの各色のインクを打滴して、媒体100の描画面にカラー画像を描画する。描画部60は、媒体100を搬送する描画胴61、描画胴61によって搬送される媒体100の描画面を押圧して、媒体100の描画面の反対側の面を描画胴61の外周面61Aに密着させる用紙押さえローラ63、及び媒体100にシアン、マゼンタ、イエロー、並びにブラックの各色のインクを打滴するインクジェットヘッド21C,21M,21Y,21K、及びインラインセンサ64を備えて構成されている。
<Drawing part>
The drawing unit 60 draws color inks of cyan, magenta, yellow, and black on the drawing surface of the medium 100 to draw a color image on the drawing surface of the medium 100. The drawing unit 60 presses the drawing cylinder 61 that conveys the medium 100, and the drawing surface of the medium 100 that is conveyed by the drawing cylinder 61, so that the surface opposite to the drawing surface of the medium 100 becomes the outer peripheral surface 61 </ b> A of the drawing cylinder 61. The sheet pressing roller 63 to be in close contact, the ink jet heads 21C, 21M, 21Y, and 21K that eject inks of cyan, magenta, yellow, and black on the medium 100, and the inline sensor 64 are configured.
図10に示すグラフは、インクジェットヘッド21を、描画位置から鉛直上方向へ移動させ、描画位置の上方の停止位置で停止させ、停止位置から鉛直下方向へ移動させた際のインクジェットヘッド21の内部流路の圧力を表している。なお、図10に示したインクジェットヘッド21の内部流路の圧力は、図6に示した供給側圧力センサ320の圧力測定値に基づく圧力変化の傾向を表したものである。なお、供給側圧力センサ320の圧力測定値に代わり、回収側圧力センサ322の圧力測定値を用いてもよい。 The graph shown in FIG. 10 shows the inside of the inkjet head 21 when the inkjet head 21 is moved vertically from the drawing position, stopped at a stop position above the drawing position, and moved vertically downward from the stop position. It represents the pressure in the flow path. Note that the pressure in the internal flow path of the inkjet head 21 shown in FIG. 10 represents a tendency of pressure change based on the pressure measurement value of the supply-side pressure sensor 320 shown in FIG. Instead of the pressure measurement value of the supply side pressure sensor 320, the pressure measurement value of the recovery side pressure sensor 322 may be used.
