摘要： A liquid ejecting apparatus includes a head unit, a movement mechanism, and a control section. The head unit has along a first direction a plurality of heads, in which a plurality of nozzles that eject a liquid onto a medium are lined up in the first direction, and the head unit forms a single raster line by ejecting the liquid while performing m number of movements relative to the medium in a second direction, which intersects the first direction. A width of the head unit in the first direction is greater than a width of the medium in the first direction. The movement mechanism causes the head unit to perform a plurality of movements relative to the medium alternately in the second direction and the first direction. The control section forms an image having a resolution that is n times a pitch of the nozzles, by forming a plurality of the raster lines by the plurality of relative movements of the head unit. Further, the control section sets a total movement amount of the head unit in the first direction when the head unit performs the plurality of relative movements, larger than an effective nozzle width of one of the heads in the first direction multiplied by (m×n−1), and smaller than the effective nozzle width×(m×n). Furthermore, the control section forms the image by setting respective movement amounts of the head unit in the first direction when the head unit performs the plurality of relative movements, larger than the effective nozzle width.
