Abstract:
1. A recording apparatus, comprising: a conveyor which conveys a recording medium in a conveyance direction; a recording head which ejects, to the recording medium, recording liquid curable by irradiation of ultraviolet light; a plurality of pretreatment heads each of which is positioned upstream of the recording head in the conveyance direction, and ejects, to the recording medium, pretreatment liquid curable by irradiation of ultraviolet light, the pretreatment heads including a downstream pretreatment head and an upstream pretreatment head which is positioned upstream of the downstream pretreatment head in the conveyance direction; a first UV irradiator which is positioned downstream of the recording head in the conveyance direction and applies ultraviolet light to the recording medium; and a controller which controls the conveyor, the recording head, the pretreatment heads, and the first UV irradiator, wherein the controller controls the conveyor and the pretreatment heads to cause: a total amount of liquid droplets ejected from the downstream pretreatment head to be greater than a total amount of liquid droplets ejected from the upstream pretreatment head; and a liquid droplet ejected from the downstream pretreatment head to overlap, on the recording medium, a liquid droplet which has been ejected from the upstream pretreatment head, and wherein a resolution of the upstream pretreatment head is higher than a resolution of the downstream pretreatment head.
