    • A method of printing an image (12) on a substrate (11) comprises controlling an inkjet printer head (10) having a plurality of nozzles (21-23) to print the image on a substrate in a series of swaths (30A, 30B). Periodically, a check for full or partial blockages in a nozzle of the inkjet printer head is performed by causing each nozzle (21-23) to print the same predetermined pattern (1, 1′, 1″) on a substrate and analysing the patterns to determine any differences between them and to identify a blocked or partially blocked nozzle if its printed pattern differs by more than a predetermined amount from that of the other nozzle(s). The checking step is carried out following each swath (30A, 30B) of the inkjet printer head (10) across the substrate (11).
    • 一种在基板(11)上印刷图像(12)的方法包括:控制具有多个喷嘴(21-23)的喷墨打印头(10),以将图像以一系列条纹(30A, 30 B)。 定期地,通过使每个喷嘴(21-23)在基板上印刷相同的预定图案(1,1',1“)来进行喷墨打印头的喷嘴中全部或部分堵塞的检查,并分析 模式以确定它们之间的任何差异,并且如果其印刷图案与另一个喷嘴的印刷图案的预定量相差超过预定量,则识别阻塞或部分阻塞的喷嘴。 在喷墨打印头(10)的每个条(30A,30B)穿过基板(11)之后执行检查步骤。
