Claim Text:
1. A liquid droplet discharge apparatus comprising: a head having a nozzle row in which nozzles capable of discharging liquid droplets onto a medium are aligned; and a movement portion which moves the head relatively to the medium, wherein the liquid droplet discharge apparatus discharges the liquid droplets onto the medium through the nozzles by causing the head to perform main scanning a plurality of number of times by the movement portion, a region from a nozzle at one end to a first nozzle located at a position away from the nozzle at the one end by a first predetermined distance is set to a first region, a region from a nozzle at the other end at an opposite side to the one end to a second nozzle located at a position away from the nozzle at the other end by a second predetermined distance is set to a second region, and a region between the first region and the second region is set to a third region on the nozzle row, a thinned-out portion is present on each of raster lines formed by nozzles in the third region, a first average nozzle usage rate of the nozzles is greater than a second average nozzle usage rate of the nozzles, the first average nozzle usage rate is an average nozzle usage rate of a first mode to form a raster of a number of a first path, and the second nozzle usage rate is an average nozzle usage rate of a second mode to form a raster in an number of a second path that is greater than the number of the first path.
