Zusammenfassung:	To provide a printing method capable of suppressing generation of bleeding of a printed layer.SOLUTION: There is provided a printing method for forming a printed layer on a substrate by an inkjet printer having an ink set containing a water-based coloring ink containing at least a first ink, a second ink, a third ink and a fourth ink, and a water-based coating liquid, including a process for discharging the water-based coating liquid from a print head and impacting a coating liquid droplet onto the substrate, and a process for discharging the first ink, the second ink, the third ink and the fourth ink from the print head in this order, and impacting an ink droplet onto the coating liquid to form the printed layer, in which the first ink has the lowest surface tension at 25°C in the water-based coloring ink.SELECTED DRAWING: None 【課題】印刷層の滲みの発生を抑えることが可能な印刷方法を提供する。【解決手段】少なくとも第１のインク、第２のインク、第３のインク及び第４のインクを含む水系着色インクと、水系コーティング液とを含むインクセットを備えたインクジェットプリンタによって、印刷層を基材上に形成する印刷方法であって、水系コーティング液をプリントヘッドから吐出させて、コーティング液滴を基材上に着弾させる工程と、第１のインク、第２のインク、第３のインク及び第４のインクをこの順番にプリントヘッドから吐出させて、インク滴をコーティング液上に着弾させることにより印刷層を形成させる工程とを含み、第１のインクは、水系着色インクの中で２５℃における表面張力が最も低い。【選択図】なし
