Paper Abstract

All printing processes basically involve some instabilities of analog nature. To overcome such instabilities, in this paper, we have developed a unique halftoning technique for stable printing. Based on the charateristics of xerography, a combination of Gaussian filter with a sigmoid nonlinear function was used to calculate the probability of toner transfer in print. We can obtain a simulated i mage in print for xerography using this nonlinear printer model. Halftone images are formed to have a good image quality under this model in a way so that the perceptive error with respect to an original gray scale image is small. To achieve this, ambiguous pixels that have their transfer probabilities within a band in our nonlinear printer model as eliminated as much as possible by an iterative improvement method. As a result, we can obtain an ideal halftone screen without anisotropy for xergraphic printer.
