Abstract:
1. A fluid-ejecting device comprising: a first nozzle column in which first nozzles configured to eject a fluid are arranged in a predetermined direction; and a second nozzle column in which second nozzles configured to eject a fluid are arranged in the predetermined direction, the second nozzle column being arranged so as to form an overlapping region in which an end part on one side in the predetermined direction is superimposed over an end part of the first nozzle column on another side in the predetermined direction; and a control part configured to cause the fluid to be ejected so that in each of a plurality of raster lines arranged in a row in the predetermined direction in the overlapping region, dots to be formed are apportioned between the first nozzles and the second nozzles; the control part being further configured to cause the fluid to be ejected so that in a raster line in the overlapping region, a pixel in which a dot formed by the first nozzles and a dot formed by the second nozzles are formed in a superimposed manner, and a pixel in which only one of a dot formed by the first nozzles and a dot formed by the second nozzles are formed are produced, the control part being further configured to cause, in the overlapping region, the fluid to be ejected from the first nozzle column and the second nozzles column according to dot data indicating dot sizes converted from an input image data, the dot data for the first nozzle column being obtained by multiplying incidence rate data for each of the dot sizes by a usage rate of the first nozzle column, the dot data for the second nozzle column being obtained by multiplying the incidence rate data for each of the dot sizes by a usage rate of the second nozzle column.
