Mitigation of Pollution-induced Deterioration of Digital Prints through Low-Temperature Storage
The Arrhenius method was used to predict the times to significant fade or yellowing of prints exposed to 1 ppm ozone or 5 ppm nitrogen dioxide. Test targets were incubated at 25°C, 30°C, 35°C, 40°C, and 45°C at 50% RH for multiple intervals up to 56 days. Cyan, magenta, yellow, and black color patches were monitored using ANSI Status A density for density loss. Unprinted, white areas were monitored using ANSI Status A blue density for paper yellowing. It was found that lower temperature does in fact reduce the rates of decay but not equally for both pollutants. Low temperature was more effective at reducing yellowing caused by nitrogen dioxide than it was at reducing the fade caused by ozone; however, cool or cold storage can clearly mitigate damage and extend the usable life of digital prints in collections.

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.
