<P>PROBLEM TO BE SOLVED: To provide a printing apparatus performing highly accurate color calibration. <P>SOLUTION: A medium is conveyed in a first direction and an ink dispensing head and a sensor that outputs a signal based on the reflected light intensity of the medium are moved in a second direction perpendicular to the first direction. A pattern containing patches representing a first gradation level, a second gradation level denser than the first, and a plurality of gradation levels between the first gradation level and the second gradation level is formed such that each patch is located at a different position in the second direction. Signals of the patch of the second gradation level and another patch are output. Then signals are output with respect to positions in the second direction in a blank region onto which ink has not been dispensed, one of the positions being located at the same position as the patch of the second gradation level, the other position being located at the another patch, so as to correct a dispensing amount corresponding to the gradation level of the another patch by using signals when the patch of the second gradation level is actually formed in all other positions except a formation position by using each output signal. <P>COPYRIGHT: (C)2013,JPO&INPIT |
