| description | To improve a printing quality when reciprocating scanning without requirement for a complicated control circuit.SOLUTION: A printing device comprises a carriage 301 in which plural ink jet heads 301b, 301c, 301d, 301e for discharging ink droplets of different colors are so located as to be arranged in a carriage scanning direction and which moves relatively to a medium, and discharges ink droplets onto the medium from the ink jet heads 301a to 301e and performs multi-pass reciprocation printing. The ink jet heads 301e, 301d, which discharge ink droplets of a color having a small brightness difference between the color and white, are located on an end side of the carriage, and the ink jet heads 301b, 301c, which discharge ink droplets of a color having a large brightness difference between the color and white, are located at a central part of the carriage.SELECTED DRAWING: Figure 6A
【課題】複雑な制御回路を必要とすることなく、往復走査時の印刷品位を向上させること。【解決手段】異なる色のインク液滴を吐出する複数のインクジェットヘッド３０１ｂ、３０１ｃ、３０１ｄ、３０１ｅがキャリッジ走査方向に並んで配置され、媒体に対して相対移動するキャリッジ３０１を備え、インクジェットヘッド３０１ｂ〜３０１ｅからインク液滴を媒体上に吐出させてマルチパス往復印刷を行う印刷装置であって、白色との明度差が小さい色のインク液滴を吐出するインクジェットヘッド３０１ｅ、３０１ｄは、キャリッジの端部側に配置され、白色との明度差が大きい色のインク液滴を吐出するインクジェットヘッド３０１ｂ、３０１ｃは、キャリッジの中央部分に配置されている。【選択図】図６Ａ |
