Various protocols for measuring the quality of color ink jet prints have been developed. An automated image analysis system has been constructed and programmed to evaluate print quality measures including color gamut, black optical density, print mottle, bleed, linewidth, raggedness, and sharpness. After defining print quality evaluations a silica-based coating was coated onto paper using the continuous coating methods of a puddle press, a rigid blade coater, and a metered size press. Using the same coating, a laboratory bench-top coating unit was used to generate single sheets of papers at equal coat weights to the continuous scale. Comparisons were made between laboratory sheets and continuously generated sheets using image analysis derived measures of print quality. The information gained is useful in deciding whether laboratory screening of various coatings formulations will be of use in projecting commercial print quality. In addition, while generating this information, the benefits of a silica gel-based coating were evident.

  • 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.
