    摘要: A color image is converted into a dot pattern for display by a color printer. The image is separated into Cyan, Magenta and Yellow color planes; a dither matrix is applied to the Cyan plane; an inverse of the dither matrix is applied to the Magenta plane; and either the dither matrix or the inverse dither matrix is applied to the Yellow plane.
