Abstract
A method of operating an ink jet printing mechanism to print onto a printable surface an image having a solid black portion occupying a selected region, and a color portion abutting the black portion. The method comprises printing a first plurality of color ink dots of a first color onto the selected region and after printing the color ink dots, printing black ink onto the selected region to generate the solid black portion. The color printing need not entirely be printed before any black is printed, and may be printed as a uniform, partial density pattern coextensive with the black regions.
