Abstract
A liquid ejection method includes determining, according to image data, an ejection pixel that is a pixel at which a liquid is to be ejected and a non-ejection pixel that is a pixel at which a liquid is not to be ejected; determining, according to the image data, a nozzle requiring flushing; and ejecting liquid from the nozzle requiring flushing to the non-ejection pixel adjacent to the ejection pixel, the non-ejection pixel being among pixels associated with the nozzle requiring flushing.
