Abstract
A printing apparatus includes a printing head, a control unit, a reading unit, and a storage unit, forms a test pattern for correcting a printing characteristic onto a medium, and corrects the printing characteristic based on a reading result of the test pattern by the reading unit. The reading unit reads a density of a printing surface on the medium in units of reading resolution in a first reading direction and a second reading direction intersecting the first reading direction. The storage unit stores an inclination angle θ (0°<θ<90°) along the printing surface of a reading direction that serves as a reference of inclination from a scanning direction intersecting an alignment direction of a plurality of nozzles of the first reading direction and the second reading direction and the scanning direction. The control unit causes the reading unit to read the test pattern in a state where the reading direction is inclined by the inclination angle θ from the scanning direction.
