Abstract
Printing is by an array of color-printing elements or nozzles in order to produce interlaced color printing while printing each line only once with each color. Print head array configurations for printing two, three and four colors include linear and parallel arrays. In one embodiment, a first color and a second color are printed on alternate lines of a first set of print lines. The first color and a third color are printed on alternate lines of a second set of print lines. Also, the second color and the third color are printed on alternate lines of a third set of print lines. By sequentially printing these consecutive sets of lines on a print medium, with each of the three pairs of colors, all of the lines of an image are printed once with each color. Other color-printing configurations are also shown.
