In applications that require spectral color information, such as fine art printing field, industry has been able to improve reproduction quality substantially in the past decade by increasing the printer gamut space and improving other print quality attributes such as metamerism. As the number of inks used in the printer is increasing and researchers are able to understand the ink and media interaction more in detail, attempting to match a color in spectral space has been possible. Similar trend is happening for electronic displays such that now there are cameras and displays with 4 or 6 color channels or filters available.

This paper focuses on the following two fundamental question in spectral color reproduction:

1. What is the optimal number of inks, and which types of inks to use?

2. How to create the ink combination that replicates a given spectral reflectance as closely as possible?

  • 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.
