ABSTRACT:
A method of operation of a liquid ejecting head, includes: reciprocating the liquid ejecting head in a first direction and a second direction which is an inverse direction of the first direction; ejecting liquid droplets from a plurality of nozzles in the liquid ejecting head while moving the head in the first direction thereby forming first patterns; and ejecting liquid droplets while moving the head in the second direction thereby forming second patterns. Each of the second patterns is adjacent to a first pattern so that the second patterns pair with the first patterns. Widths of the first patterns or the second patterns, or both, in the first direction are different so that each pair has a different correction amounts.
