Color correction for bi-directional printing in inkjet printers

摘要

In the course of the operation of a bi-directionally printing inkjet printer, travel of the printhead in the left-to-right direction results in the ability to apply colored ink droplets onto a pixel location in one sequence. However, when the printhead moves right-to-left, the sequence by which the colors may be applied is reversed. Therefore, hue shift alters the appearance of a pixel depending on the direction of printhead movement at the time of printing. In one implementation, a system and method of color data translation includes a first color mapping look-up table for left-to-right printhead travel and a second color mapping look-up table for right-to-left printhead travel. Accordingly, greater control over print output is obtained. In particular, hue shift between swaths, wherein each swath is associated with printhead travel in a particular direction, are avoided.
