发明名称 INK JET PRINTING APPARATUS AND INK JET PRINTING METHOD
摘要 An ink jet printing apparatus and an ink jet printing method are provided which are capable of minimizing image impairments caused by a bias of satellite positions even when an odd-numbered-pass bidirectional multi-pass printing is performed. To this end, in an odd-numbered-pass bidirectional printing, a mask pattern, in which print permitted pixels and print non-permitted pixels are arranged such a way that a percentage of pixels in which predetermined two inks are permitted to be printed by scans in different directions is higher than a percentage of pixels in which the predetermined two inks are permitted to be printed by scans in the same directions, is used. This increases the probability of satellites of the two types of the inks printed in the same pixels being printed on both sides of main dots, thus allowing a uniform image to be produced even by an odd-numbered-pass bidirectional printing.
