Model-Based Memory-Efficient Algorithm for Compensation of Toner Overdevelopment in Electrophotographic Printers

Abstract

Text and line attributes are an integral part of print quality. In this article the authors study artifacts introduced by the electrophotographic process that make text and thin lines with high colorant content appear blurred. The authors characterize the amount of blurriness of a specific print engine by measuring edge transition widths and correlate their results with previous psychophysical studies regarding perception of blur to determine the acceptable limits of the printer's performance. They propose a memory efficient algorithm that requires minimal modifications to the printer engine architecture to attain those limits. They demonstrate that the proposed solution outperforms the currently implemented solution in terms of color and texture preservation.
