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.

  • For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
