Abstract:
An inkjet printer includes head units each having an upstream head and a downstream head. The downstream head is adjacent to the upstream head as seen in a width direction of a recording medium, and is positioned downstream from the upstream head as seen in a transport direction. Each of the upstream and downstream heads includes a plurality of nozzles, and some of the nozzles in the upstream head and some of the nozzles in the downstream head overlap each other in widthwise position. A controller for the inkjet printer includes a ratio changing part for changing a usage ratio between the nozzles in the upstream head and the nozzles in the downstream head in an overlap region that is a widthwise range in which the overlapping ones of the nozzles are present. The occurrence of color irregularities in the overlap region is suppressed by appropriately setting the usage ratio.

Claim (Index 12):
A method of inkjet printing a multi-color image on a recording medium by ejecting inks of different colors from respective head units toward the recording medium while moving the recording medium and the head units relative to each other in a transport direction, each of said head units including an upstream head, and a downstream head adjacent to said upstream head as seen in a width direction orthogonal to said transport direction and positioned downstream from said upstream head as seen in said transport direction, each of said upstream head and said downstream head including a plurality of nozzles arranged in said width direction, some of said nozzles in said upstream head and some of said nozzles in said downstream head overlapping each other in widthwise position, said method comprising the steps of:\n a) changing a usage ratio between said nozzles in said upstream head and said nozzles in said downstream head in an overlap region that is a widthwise range in which the overlapping ones of said nozzles are present; and b) ejecting said inks in the changed usage ratio from said upstream head and said downstream head.
