An inkjet printer capable of minimizing chromatic variation due to an ink overlapping (or overlaying) order when printing in a bidirectional mode. Bright color ink dots and dark color ink dots are arranged alternately within the same swath when printing in the bidirectional mode. Plural swaths with different overlapped colors consisting of these dots are arranged alternately in both the main and sub directions to perform overall chromatic averaging.

Inkjet printer capable of minimizing chromatic variation in adjacent print swaths when printing color images in bidirectional model

An inkjet printer capable of minimizing chromatic variation due to an ink overlapping (or overlaying) order when printing in a bidirectional mode. The inkjet printer comprises an inkjet head that has a plurality of inkjet nozzles. The nozzles include at least one nozzle for firing the darkest color ink, at least one nozzle for firing the brightest color ink and at least one nozzle for firing a mid-color ink. The nozzle for firing the brightest color ink can be located downstream from or the nozzle for firing the darkest color ink can be located upstream to the nozzle for firing a mid-color ink whenever the inkjet head travels in the main scan direction regardless to both directional passes.
