  • System and method for reducing inter-color bleeding in liquid ink jet printing
    Patent number: 6412938
    Abstract: Printing systems and methods that reduce inter-color bleeding between dark and light colored inks without losing productivity of a color ink jet printer by distributing the printing of a total amount of black ink required in a single swath over multiple passes while each of the color inks required for the same swath is printed in a single pass. For example, the print method may print a single swath by printing portions of the slow dry black ink in three passes while printing each of the fast dry color inks in single passes.
