  • Printhead for color printer providing image edge enhancement
    Patent number: 5057852
    Abstract: Apparatus and method of producing image edge enhancement in four-color printers. The true black color is aligned for printing between the cyan, magenta, and yellow colors. When a black edge is desired, process black and true black are both used to produce the pixels along the edge. Because the process and true black pixels are interleaved with each other along the edge, the effective resolution is doubled and the sharpness is enhanced along the edge.
