Correcting method, liquid ejecting apparatus, computer program, computer system, and correction pattern

摘要

A method of correcting a difference between dot formation positions in a reciprocally operation of a liquid ejecting head, includes the steps of: reciprocating the liquid ejecting head along a liquid ejecting path in a first direction and a second direction which is an inverse direction of the first direction, the liquid ejecting head having a plurality of nozzles for ejecting a liquid droplet; ejecting the liquid droplet while moving the liquid ejection head in the first direction so as to form first patterns; and ejecting the liquid droplet while moving the liquid ejection head in the second direction so as to form second patterns, each of the second patterns being adjacent to each of the first patterns so that the second patterns respectively pair with the first patterns. Each of the first patterns and the second patterns has a plurality of dots placed in the first direction and a third direction perpendicular to the first direction to form a block. Widths of at least one patterns of the first patterns and the second patterns in the first direction are different one another so that pairs of the first patterns and the second patterns have different correction amounts.
