    摘要: A technique of forming a bar of a bar code on print media by a printing device having a plurality of colorants. Each one of the individual bars has a leading edge and a trailing edge that help to define a central region of the bar. The relative locations of the leading edge and trailing edge are determined and a first colorant, usually black, is deposited at the leading edge. A composite of the first colorant, and the other printhead colorants, are deposited in the central region while the first colorant is deposited at the trailing edge. A bar of a bar code produced by this technique has a clearly defined leading and trailing edge for bar code readers to measure while the central region of the bar includes a composite of colorants.
