Detecting Appearance Changes with Spectrocolorimetry and Densitometry
North skylight, which was filtered through window glass and thus contained a substantial component of UV A, was used to cause rapid fading of some samples. Light exposures that mimicked museum exhibition conditions - tungsten lighting filtered through UV blocking plastic glazing - were also used. As expected, the colorants were much less fugitive in these latter conditions. Most colors withstood total experimental exposures equivalent to that which would be endured over several thousand hours of gallery exhibition, before the extent of change detected was considered significant.

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.
