摘要:
The present invention provides an ink jet recording apparatus capable of recording high-quality images in which not only color shading caused in the process of reciprocating recording is prevented, but also bleeding between colors inherent in a multi-pass recording method is reduced. The position of the top of ejection orifices in a second ejection orifice row for ejecting color ink is spaced a length away from a first ejection orifice row for ejecting black ink. The length is determined according to values m, n and such a condition that the value a makes (m+a) an even number. Under the circumstances, recording is performed by reciprocating scanning, which makes differences in recording time between colors equal to each other.
