Abstract
A check pattern is printed which makes it possible to detect, with high precision, individual patterns corresponding to nozzles of a print head of an inkjet printing apparatus. More specifically, after an alignment mark is printed, ejection of an ink from the nozzles is stopped for a certain time. Because of this stoppage time, the concentration of a coloring material of the ink ejected from the nozzles increases, whereby the optical density of an analysis pattern which is printed later can be increased. In this manner, a scanner can read, with high precision, the patterns corresponding to the nozzles.
