Abstract

A method of multi-color printing in a single pass using a fixed pagewide array of monochrome inkjet printheads. The printheads are aligned with each other in a media feed direction and the method includes the steps of: feeding print media along the media feed direction past a first printhead positioned furthest upstream in the array, a third printhead downstream of the first printhead and a second printhead positioned furthest downstream in the array; printing a yellow ink onto the print media using the first printhead; printing a black ink onto the print media using the third printhead; and printing a cyan or magenta ink onto the print media using the second printhead.
