Inkjet printer model-based halftoning

There have been many advances in printer model-based halftoning. However, virtually all of this work has focused on electrophotographic (EP) printers. The lack of comparable work for inkjet (IJ) printers may be due to the fact that IJ printers do render dots that have a nearly hard, ideal profile, and are much more stable than dots rendered by EP printers. However, as we shall see, IJ printers do exhibit dot displacement errors that are caused by misaligned nozzles in the printhead, and which appear random in nature. These error can cause significant artifacts in the printed image. The goal of this paper is to model the IJ printer, and then to incorporate this model into halftoning algorithms so that high print quality can be achieved. Here, we develop a stochastic printer model based on the dot statistics of the IJ printer.
