Liquid ejecting device and method for adjusting liquid ejecting device

A method for adjusting a liquid ejecting device that includes a head having a plurality of nozzles for ejecting droplets onto a recording medium, and a movement unit configured to move the head relative to the recording medium in a relative movement direction, wherein

• the method comprising:
• a test pattern recording step for recording, by controlling the head and the moving unit, a test pattern on the recording medium, the test pattern having a plurality of patches from which a plurality of candidates for a correction value for correcting a landing position, at which the droplet lands on the recording medium, in the relative movement direction are obtained;
• a correction value candidate deriving step for deriving the plurality of candidates for the correction value from the test pattern;
• and
• a correction value determining step for determining the correction value by statistically processing the plurality of derived candidates for the correction value.
