DOI or Distinctness of Image is now recognized as an important appearance attribute, particularly for photographic images. In NIP21, we introduced our first-generation portable instrument for DOI measurement, the DIAS. Since its introduction, the DIAS has been used primarily by printer and media manufacturers for quantitative analysis of print and media quality. In this paper, we describe the second generation device, the DIAS-II, with a broader measurement range capability. The DIAS-II is even more compact, more reliable, easier to use, and costs less than the first generation device. We discuss the new hardware design, improvements in the analysis method, techniques for enhancing the manufacturability and the performance of the system, and applications beyond print media characterization.

  • 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.
