Abstract

A multi-color printer has an array of monochrome fixed inkjet printheads aligned in a media feed direction. The printer includes: a first printhead positioned furthest upstream relative to the media feed direction; a second printhead positioned furthest downstream relative to the media feed direction; and a third printhead positioned between the first and second printheads. Each printhead is supplied with a respective ink from a multi-color ink set, the first printhead being supplied with a lowest luminance ink of the ink set and the third printhead being supplied with a highest luminance ink of the ink set.
