Abstract:
A liquid ejecting apparatus includes a liquid supplying unit that supplies the liquid, a head unit that has a nozzle row, in which a plurality of nozzles for ejecting the liquid is aligned, a control unit that forms a raster area, in which a plurality of ejection dots in units of the nozzle rows is aligned in a main scanning direction, an ejection amount calculating unit that calculates ejection amounts of the liquid needed for forming the ejection dots, and a division scanning unit that divides the raster area so as to be formed by performing a plurality of head scanning operations in accordance with a transitional change in the ejection amounts that is formed by aligning the ejection amounts calculated by the ejection amount calculating unit in the order in which the ejection dots in units of nozzle rows are formed.
