Abstract
Improved methods and apparatuses are provided for use in printing color swaths in a bi-directional printing device. The bi-directional printing device is configured to use a plurality of color inks including at least one light color ink and at least one dark color ink. One method includes selectively printing at least one dark color ink on a print media based on a non-uniform probabilistic print mask function, and selectively printing at least one light color ink on the print media based on a substantially uniform probabilistic print mask function.
