Patent ID: 7354127

Claim:
A method for testing ejection of a clear ink, comprising the steps of: ejecting a clear ink toward a medium from a clear-ink nozzle to form an ejection-test pattern; ejecting a same color ink, from at least two color-ink nozzles, toward said medium to form said ejection-test pattern; and checking whether or not there is ejection failure in said clear-ink nozzle based on detection information from a sensor for detecting said ejection-test pattern that has been formed on said medium, wherein said clear ink is ejected to cover a region entirely, wherein said same color ink is ejected to cover said region entirely, wherein said region has a plurality of dots that are formed with said clear-ink ejected only from said clear-ink nozzle and a plurality of dots that are formed with said same color ink ejected from said at least two color ink nozzles.
