Liquid ejection method and liquid ejecting apparatus

A liquid ejecting apparatus comprising:

• a feed mechanism that feeds a medium in a feed direction;
• an ejection head that ejects liquid and that is movable in a main scanning direction;
• a sensor that detects a position of an edge of the medium and that is movable in the main scanning direction together with the ejection head;
• and
• a controller that sets, based on a result of detecting the position of the edge of the medium, an area to which the liquid is to be ejected from the ejection head,
• wherein the main scanning direction is a direction in which the ejection head travels,
• wherein the feed direction is a direction that intersects with the main scanning direction,
• wherein, when the ejection head makes a plurality of movements by traveling in the main scan direction, the controller changes, in accordance with a result of detection of the position of the edge of the medium performed by the sensor in a first movement, at least one of a start position and a terminating position of the area to which the liquid is to be ejected from the ejection head in a second movement subsequent to the first movement, and
• wherein the controller causes a degree of change of the at least one of the starting position and the terminating position to vary in accordance with a magnitude of a feed amount between the first movement and the second movement.
