Abstract: The present invention addresses the reformatting of a digital “ready to print” data file into a continuous tone (32 or 24 bit) file whereby discrete values in the tone range are uniquely assigned to specific binary combinations. The purpose for this transform is to facilitate further manipulation of preprocessed data. One application of the present invention is to exist as a critical piece of proofing workflow for a technology that reduces continuous tone data into a binary form representing droplet selection prior to output.

Abstract: The method for a printing device determines the maximum amount of colorant that is to be deposited on a specific region of print media to form an image with a reduced quantity of visual defects. The method entails inputting at least one colorant value on the specific region of print media. The at least one colorant value indicates a total amount of at least one colorant that is to be applied by the printing device. A colorant limit is derived for each color or combinations thereof according to a text ink limit algorithm and each derived color ink limit is applied to the image to limit the quantity of ink used by the printing device when one of the derived colorant limits is exceeded.
