One of the major digital printing technologies used for production printing is dry-toner electrophotography. The main technical challenge is print quality and many researches have been done to improve it in the recent years. In our study, dry-toner color electrophotography was compared to conventional offset printing. A Xerox iGen3 press and a Heidelberg Speedmaster press were used. The substrates used were different uncoated and coated paper stocks. The GATF 11x17 Four-Color Test Form was printed on the papers by both printing presses. Print quality, such as color gamut, dot gain, print contrast, and trapping, were evaluated and compared. Higher dot gains were found on Speedmaster than on iGen3 except for black color. Higher print contrast values were found for iGen3 than for Speedmaster except for black color. Wider color gamuts were achieved on iGen3 than on Speedmaster, especially on uncoated papers. With high print quality, it is expected that more production printing will be done by dry-toner color electrophotography.

  • 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.
