Ink jet printing apparatus and ink jet printing method |
摘要 |
The ink jet printing apparatus of this invention is intended to reduce degradations in image quality caused by color mixing due to bleeding of inks of different colors and thereby enable printing an image with high quality at high speed. To this end, in the ink jet printing apparatus of this invention, a plurality of different nozzle groups are main-scanned M times (M>=2) over a print area to print all print data to be printed on the print area to complete an image. The print head, successively perform the main scans over the print area in such a way that the print head, located at the front position in the printing order, performs an Mth main scan with a lower print density than that of an Nth main scan (1<=N<M).
