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