Abstract
A color correcting method for compensating a color drift in a printing device includes determining an ink recording rate having a maximum variation of colorimetric data from among a plurality of stages of ink recording rates. 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. The color correcting method includes controlling the printing device to print a standard image of the determined ink recording rate on the printing medium. The color correcting method also includes compensating a color drift in the printing device having printed the standard image 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.
