1. A color correcting method for compensating a color drift in a printing device for printing on a printing medium a printing image corresponding to printing data by using a printing head for adhering ink on the printing medium, the method comprising: determining an ink recording rate having a maximum variation of colorimetric data from among a plurality of stages of ink recording rates, wherein the variation of colorimetric data occurs by means of a variation of an amount of ink adhering on the printing medium on each printing device; controlling the printing device to print a standard image of the determined ink recording rate on the printing medium; and compensating a color drift in the printing device by correcting the printing data based on a result of comparing the standard image of the ink recording rate having the maximum variation printed on the printing medium with a reference standard image.
