Abstract
In a printing apparatus, print position shift caused by a posture change of a print head is appropriately reduced irrespective of causes of the posture change. Specifically, a test pattern is printed, and then, an inclination of a carriage is calculated based on the read result. On this test pattern appears, for example, not only landing position shift caused by the rolling posture change of the carriage but also synthesized position shift caused by a plurality of kinds of posture changes of the carriage. That is to say, on the test pattern to be printed can appear synthesized position shift caused by a plurality of kinds of posture changes occurring on a print head at this time. The posture of the carriage is corrected in such a manner as to suppress the synthesized position shift.
