In this paper, we consider a dual-mode halftoning system for electrophotographic printers; a low frequency halftoning for smooth regions and a high frequency halftoning for detail regions. This screen-switching approach has a stable halftone pattern in smooth areas and preserves fine rendering in detail areas, but undesirable jaggies may occur along the boundaries where the low and high frequency screens meet. To reduce the jaggies, we propose a new approach to blend two halftone patterns based on a transition region built around boundary pixels. In addition, we provide an implementation methodology which requires simple structure, minimal memory, and small processing time.

  • 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.
