Abstract
A method of solid ink printer operation compensates for missing black ink in solid fill areas. The method includes ejecting at least one other color of ink into a black solid fill area at a predetermined distance to the area missing the black ink. The additional non-black ink urges black ink between the non-black ink and the area missing the black ink to migrate into the area in which the black ink is missing.
