Paper Abstract
Digital halftoning provides a mechanism for rendering continuous-tone images on devices such as printers. With
electrophotography, the deposition of toner within the area of a given printer addressable pixel is strongly
influenced by the halftone values of the immediately neighboring pixels. To account for these effects, it is
necessary to embed a printer model in the halftoning algorithm.
In our previous work, we used an efficient strategy to account for the impact of a 5x5 neighborhood of pixels
on the central pixel absorptance. Now we examine the potential influence of a much larger neighborhood (45x45)
of the digital halftone image on the measured value of a printed pixel at the center of that neighborhood. The
experiment shows that the extended model yields a significant improvement in the accuracy of the prediction of
the pixel values of the printed and measured halftone image.
