Kodak Tests of Digital Prints, PDF: TPR conducted an extensive test on the stability of photographic prints made from a variety of systems from multiple vendors. The report compares the performance of the various images under accelerated conditions to assess their respective permanence and to make life projections.

Overview: Accuracy in Photo Print Life Prediction, PDF: Although the methodology for developing life predictions has been in use for some years in the industry, it is becoming clear that the implied precision in the use of a single value in years cannot be scientifically supported due to much variability between the measurement of an assumed exposure and the actual exposure and observation conditions. Current print life predictions are likely to be invalid in almost all real life exposure situations and the data for the long term effects of combined exposures is scant to say the least. This paper examines the implications of this on real life print exposure. Peter J Mason, Senior Vice-President of Torrey Pines Research.

Presentation: September IS&T NIP24 conference - Accuracy in Print Life Prediction -, PDF: Presented September 2008 by Peter J Mason, Senior Vice-President of Torrey Pines Research.

Exec Summary Accelerated Life Testing of Digital Images, PDF: This document summarizes the effects of various contaminants (such common durability factors as UV light, pollutants, temperature and humidity) as well as "casual contaminants" on the life time of digital images. Other factors tested included handling and accidental contaminants, storage contaminants, and writing inks.  Conclusions and recommendations for developing test standards are included.  The full 148-page detailed report may be obtained by contacting TPR directly by phone or e-mail and requesting a copy.

Effect of Various Contaminants on Ink Jet Photo, PDF: This document contains an enhanced slide presentation of the results of the above accelerated life test study.

Image Permanence - Comparing The Technologies ,PDF: The paper addresses image permanence performance among inkjet, silver halide, EP, and thermal printer systems. Testing and methods are discussed, with conclusions and recommendations. The paper was presented by Peter Mason, TPR's Senior VP and CTO at the IS&T NIP 23 conference in Anchorage, Alaska on September 20, 2007. ***
