Abstract:
1. A liquid ejection method of ejecting liquid from a movable ejection head onto a medium, said method comprising: detecting a position of an edge of the medium, wherein the edge is substantially perpendicular to a main-scanning direction; and setting, based on a result of detecting the position of the edge of the medium, an area to which the liquid is to be ejected, wherein the main-scanning direction is a direction in which the movable ejection head travels; wherein the area to which the liquid is to be ejected is set by changing, according to a feed amount of the medium fed after the position of the edge of the medium has been detected, at least either a starting position or a terminating position, in the main-scanning direction, for ejecting the liquid from the ejection head being moved; and wherein the ejection head starts liquid ejection at the starting position and terminates liquid ejection at the terminating position; and the greater the feed amount is, the further the start of liquid ejection is advanced or the further the termination of liquid ejection is delayed in the main-scanning direction.
