Abstract
The present invention provides a method for processing color image data to maintain edge quality in an image recorded on a receiving medium. The method includes receiving a target pixel comprising multiple separation pixels, each separation being associated with a separate color plane and having at least three states, a first state corresponding to depositing no ink, a second state corresponding to depositing one ink drop, and a third state corresponding to depositing more than one ink drop; determining if the target pixel is within a black border region near a black/non-printed interface; and if so, setting the separation pixel associated with a black color plane to a selected black pixel state.
