    • A nozzle control method and a nozzle control device. The nozzle control method includes discriminating between the nozzle(s) to eject the ink droplets from the nozzle(s) not to eject the ink droplets; and generating a pressure wave with a predetermined amplitude in the nozzle(s) not to eject the ink droplets when the ink droplets are ejected from the nozzle(s) to eject the ink droplets. Accordingly, it is possible to produce a color filter with a uniform thickness regardless of the print pattern. The ink droplets with a constant size can be ejected when the nozzle pitch of the print head is not the same width as the print pattern width. Therefore, the print quality is improved by a uniformizing ink thickness in which the print job is performed to the print medium regardless of the number of nozzles ejecting the ink droplets concurrently.
    • 喷嘴控制方法和喷嘴控制装置。 喷嘴控制方法包括区分喷嘴以喷射墨滴而不喷射墨滴; 以及当喷嘴喷射墨滴以喷射墨滴时,在喷嘴中产生具有预定振幅的压力波,以便不喷射墨滴。 因此,无论打印图案如何,都可以制造均匀厚度的滤色器。 当打印头的喷嘴间距不同于打印图案宽度的宽度时,可以喷射具有恒定尺寸的墨滴。 因此,不管同时喷射墨滴的喷嘴的数量如何,通过均匀化油墨厚度来提高打印质量,其中对打印介质执行打印作业。
