Patent ID: 8608272

Claim:
A method of inkjet printing comprising: receiving digital data corresponding to an image to be printed with an inkjet printing apparatus; generating a coverage area map that identifies areas of the image to be printed that have different coverage area densities; identifying a coverage area density for each area identified by the coverage area map, the coverage area density for each area being identified by weighting gloss level data differently for each color plane in an area identified in the coverage area map; selecting a halftone level for clear ink to be ejected onto each area identified by the coverage area map, the halftone level selected for each area corresponding to the coverage area density for the area; operating a first plurality of inkjet ejectors for the inkjet printing apparatus to form the image to be printed on an image receiving member with at least one colored ink; and operating a second plurality of inkjet ejectors to eject clear ink at the selected halftone levels onto the image receiving surface, the second plurality of inkjet ejectors being operated with reference to the selected halftone levels to eject different amounts of clear ink onto the different areas identified by the coverage area map.
