Abstract
A method and apparatus for printing color images by binary construction from individual colorant dots formed in pixel arrays uses a multi-pass print mode and print masks. Based on color map requirements, a pixel is given a density level. Print masks are provided having mask numbers representing a specific density level. A particular colorant dot is formed only on a pass when the mask number is less than or equal to the specific density level for a target pixel.
