An inkjet printhead includes a number of printhead modules arranged end-to-end to span a width of a page, the printhead modules defining color channels also to span the width of the page. A plurality of inkjet nozzles is arranged on the modules such that rows of the nozzles span the width of the page, with at least one row of nozzles in fluid communication with respective channels, the nozzles capable of being fired to eject ink from their associated channels, the nozzles of each row on an associated module defining a segment of nozzles. A printer controller controls a firing sequence of the nozzles and is configured so that nozzles from segments associated with different color channels are fired sequentially during a predetermined time allocated for firing a line of nozzles.
