Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an inkjet printing method that can prevent or suppress occurrence of streak of printing and achieve production of a printed matter with precision having excellent color developing performance.SOLUTION: The inkjet printing method, which uses a liquid spray head having a head unit, in which a plurality of nozzles for spraying liquid are provided in the number corresponding to minimum formation densities of dots to be formed on a surface of a printed medium, which is provided with one or more nozzle arrays having a plurality of nozzles provided at equal nozzle pitch, performs: a first scanning step of spraying liquid from the head unit and forming liquid droplet dots only on non-printed surface of the printed medium; and a second scanning step of impacting liquid to an intermediate position between adjacent dots on a printed surface consisting of dot groups formed in the first scanning step so as to form dots of liquid droplets, where the liquid to be sprayed from a nozzle at a downstream end of the head unit in the second scanning step impacts to the printed surface so as to form the dots of liquid droplets.SELECTED DRAWING: Figure 10 【課題】印刷スジの発生を防止または抑制し、高精緻で優れた発色性を有する印刷物の製造を実現可能とするインクジェット印刷方法の提供。【解決手段】液体を噴射する複数のノズルが、被印刷媒体の表面に形成される目的の最低ドット形成密度に対応した個数設けられ、かつ当該複数個のノズルが等しいノズルピッチで設けられたノズル列を１つまたは２つ以上具備してなるヘッドユニットを有する液体噴射ヘッドを用いるインクジェット印刷方法であって、前記ヘッドユニットから液体を噴射して、被印刷媒体の非印刷面のみに液滴ドットを形成する第一の走査工程と、前記第一の走査工程により形成されたドット群からなる印刷面の隣接するドットの中間位置に液体を着弾させて液滴ドットを形成する第二の走査工程とを含んでなり、前記第二の走査工程において前記ヘッドユニットの下流端ノズルから噴射される液体が前記印刷面に着弾して液滴ドットを形成する。【選択図】図１０
