Abstract
A liquid ejecting device includes a supporting unit supporting a medium, an ejecting unit ejecting liquid onto the medium, a scanning driving unit moving the ejecting unit, and a control unit controlling the ejecting unit and the scanning driving unit. The control unit is configured to be capable of performing, a first processing for forming a test pattern, and acquiring an ejection velocity parameter associated with an ejection velocity of the liquid detected from the test pattern, a second processing for calculating the ejection velocity of the liquid from the ejection velocity parameter, calculating a first correction component that depends on the calculated ejection velocity, and setting a correction value including the first correction component, and a third processing for correcting ejection timing of the liquid using the correction value, when the liquid is ejected from the ejecting unit onto the medium as the ejecting unit is moved.
