Abstract

An apparatus and method for use in printing a swath in a multipass printing device are disclosed. The method comprises selectively depositing a drop of ink associated with a pixel to be printed on a print media based on a substantially uniform print mask function during a first pass of a print head, and selectively depositing a further drop of ink associated with the pixel on the print media based on a ramp print mask function during a further pass of the print head.
