Ink jet printing apparatus, ink jet printing method and print head |
摘要 |
An ink jet print head is provided which can print a high-quality image with no density variation-caused lines at high speed and which can be manufactured at low cost and with ease. For this purpose, the print head of this invention has a plurality of nozzle groups each having at least one nozzle array arranged in a predetermined array direction Y crossing a relative motion direction X. A distance in the relative motion direction between the nozzles in each nozzle group adjoining each other in the array direction Y is set almost equal to a distance in the relative motion direction between the nozzle groups adjoining each other in the array direction Y.
