Abstract: A liquid discharge apparatus includes a recording device and a recording controller. The recording controller alternately performs a main scanning control and a sub-scanning control. The main scanning control controls discharging liquid while moving the recording device and a recording medium relative to each other in a main scanning direction. The sub-scanning control controls the recording device to discharge the liquid from at least two recording elements of the recording device, in accordance with at least two times of the main scanning control performed at positions on the recording medium in a sub-scanning direction. The recording device discharges the liquid, within a range in the sub-scanning direction corresponding to a position of the recording head. The recording controller performs the main scanning control for discharging the liquid based on discharge order mask patterns different from each other in a plurality of regions in the main scanning direction.

Abstract: A liquid discharge apparatus includes a liquid discharge head, an irradiator, a carriage, and a conveyance controller. The liquid discharge head discharges liquid to a recording medium to form a liquid application surface. The irradiator emits active energy rays toward the liquid application surface. The carriage is mounted with the liquid discharge head and the irradiator. The conveyance controller conveys the carriage. The irradiator includes a first irradiator that is provided on one side surface of the carriage in a direction in which the carriage is conveyed and a second irradiator that is provided on another side surface of the carriage in the direction in which the carriage is conveyed. A position of the first irradiator and a position of the second irradiator in a direction perpendicular to the direction in which the carriage is conveyed, on irradiation of the active energy rays, are different from each other.
