Abstract
An inkjet printing apparatus which performs printing by performing scanning using a print head has a problem in that quality of an image of a ruled line is degraded when ink is not ejected for a certain period of time. To address this problem, control is performed such that power for driving the print head for unit regions including pixels having a ruled-line attribute becomes higher than power for driving the print head for unit regions which do not include the pixels having the ruled-line attribute. By this, a high-quality ruled-line image may be printed.
