Abstract
There is provided a method of acquiring a correction value of a liquid discharging apparatus that includes a first nozzle row, a second nozzle row, a third nozzle row, and a fourth nozzle row, the method includes: acquiring the amount of deviation (heterogeneous row error) of a dot formed by the third nozzle row in the predetermined direction, acquiring the amount of deviation (overlapping area error) between the dot formed by the third nozzle row and a dot formed by the fourth nozzle row in the predetermined direction, and acquiring a correction value which causes discharge data assigned to the fourth nozzle row to shift in the predetermined direction based on the heterogeneous row error and the overlapping area error.
