Zusammenfassung:	The present invention provides an inkjet printing method. The inkjet printing method in which ink is ejected on a substrate by using a head having a plurality of nozzles may comprise: a grading step of determining a grade of nozzles by measuring discharge performance of the nozzles; a nozzle selecting step of selecting a use nozzle that may participate in printing of the substrate among the nozzles based on the grade determined in the grading step; and a printing step of discharging ink to the substrate by using at least one of the nozzles used, thereby capable of efficiently performing a printing process on the substrate. 본 발명은 잉크젯 인쇄 방법을 제공한다. 복수의 노즐이 형성된 헤드를 이용하여 기판 상에 잉크를 토출하는 잉크젯 인쇄 방법은, 상기 노즐들의 토출 성능을 측정하여 상기 노즐들의 등급을 결정하는 등급화 단계; 상기 등급화 단계에서 결정된 상기 등급에 기초하여, 상기 노즐들 중 상기 기판의 인쇄에 참여할 수 있는 사용 노즐을 선정하는 노즐 선정 단계; 및 상기 사용 노즐 중 적어도 하나 이상의 노즐을 이용하여 상기 기판에 잉크를 토출하는 인쇄 단계를 포함할 수 있다.
