ABSTRACT:
Ejection of a clear-ink nozzle is inspected with ease. When forming an ejection-test pattern for a clear ink, for example, the clear ink is ejected toward a medium from a clear-ink nozzle to form the ejection-test pattern, and a color ink is ejected toward a region in which the clear ink is to adhere from at least two color-ink nozzles to form the ejection-test pattern.
