There is growing recognition that besides specular gloss, the attribute of distinctness of image (DOI) is important in accurately characterizing the surface appearance of glossy inkjet paper. DOI refers to the sharpness of images reflected from a surface. At present, no consistent and quantitative method has been adopted to report DOI in the characterization of digital prints.

The objective of this study is to assess DOI as a suitable metric for characterization of glossy inkjet papers using currently available methods. This study was conducted on unprinted sheets due to the complexity of choosing an appropriate test image and printer combination. Commercial glossy inkjet papers, both porous and swellable, were measured using three different methods for measuring DOI. The results were compared to each other and to surface smoothness, 60° gloss, and panel studies on visual perception of photo-like glossy appearance. The results demonstrate that even low gloss sheets (< 40 units), typically porous, may be perceived as having a photo-like surface due to high DOI. Certain measured parameters using available methods do correlate with the perception of DOI.

  • 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.
