ABSTRACT:
In the preferred form, a scanning carriage in a color inkjet printer houses a high resolution printhead for black (or monochrome) printing and one or more lower resolution printheads for color printing. The nozzle arrangements, paper feed increments, and ink drop firing frequency for the black printhead and color printhead(s) are selected to provide various alignments between the larger color ink dots and the smaller black ink dots to achieve maximum ink coverage with a minimum of ink or to achieve additional color shades.
