A liquid droplet discharging apparatus includes a printing unit that moves a discharging head in a scanning direction and prints a test pattern on a medium by discharging a liquid droplets from nozzles of the discharging head, a transporting unit that intermittently transports the medium in a transporting direction, and a reading unit that reads the test pattern. The printing unit prints the test pattern by overlapping a transportation reference pattern and a transportation deviation pattern, in order to correct at least any one of a transportation amount of the medium being transported by the transporting unit and a discharging position to which the liquid droplets are discharged from the nozzles. The reading unit reads a completed part of the test pattern at the same time as printing the test pattern by the printing unit.
