Abstract
In an ink jet printer, bleed between the boundaries between color and black are avoided by printing process black and black ink in an alternating pattern for the first two dots. Logic (62) determines the boundary from a bit map and issues the control signals for alternating lines (66, 68). Best results are experienced when the process black is printed before the black ink as the vehicle of the colored inks apparently supports penetration of the black ink.
