Abstract
An inkjet printing apparatus and an inkjet printing method are provided which can correct, with high precision, print position deviations among a plurality of printing element arrays in each of a plurality of print modes that use different groups of printing elements in each printing element array. The adjustment values for the print position deviations between the first and second printing element arrays are differentiated between the high-speed mode and the high-quality mode. In the high-speed mode, all printing elements in the first and second printing element arrays are used. In the high-quality mode, a part of the printing elements in each of the first and second printing element arrays are used. Based on these adjustment values, the ink ejection timings of the first and second printing element arrays are adjusted.
