Patent number: 7192112Abstract: Disclosed are a printing apparatus and printing method which suppress degradation of the image quality caused by discharge failure complement. In the printing apparatus, virtual data are generated for predetermined dots in a scanning direction on the basis of printing data of a plurality of dots in the scanning direction of an inkjet printhead that are printed by an ink discharge failure nozzle among a plurality of nozzles. The priorities of dots subjected to complementary printing among a plurality of dots within a predetermined adjacent area where the printing data and virtual data are printed are decided on the basis of the printing data and virtual data. A position subjected to complementary printing is decided on the basis of the priorities, printing data, and virtual data. Printing data and virtual data which actually cause ink discharge are so moved as to print at the position. Corrected printing data to be actually printed is generated on the basis of the moved data.Type: GrantFiled: August 31, 2004Date of Patent: March 20, 2007Assignee: Canon Kabushiki KaishaInventors: Hideki Nakanishi, Kazuhisa Kuruma, Takayuki Murata, Yuichiro Suzuki, Hitoshi Nishikori, Masao Maeda
