Patent attributes
What is disclosed is a system and method for improving vector halftoning in ink-jet printers capable of dot-on-dot printing. In one embodiment, n input Ci/Mi/Yi channel and a colorant Ki are received. If any of the Ci/Mi/Yi is greater than 100−Ki then that channel is clipped to 100−Ki. Next, a minimum total coverage area of a secondary color RGB dot required to achieve a remaining CMY coverage area is determined. If the minimum total coverage area is non-zero, then the following steps are performed. Each of a primary output Co/Mo/Yo is determined. Each of the primary outputs is then scaled by a ratio of the remaining primary color area over the total remaining toner coverage. The results are sorted and secondary color RoBoGo outputs are determined from the sorted results.
