With the recent proliferation of affordable, high-quality digital cameras, scanners, and digitized image files made from color negative and transparency originals, there has been tremendous growth in the use of inkjet printers for printing color photographs. As inkjet printers move into mainstream markets, many questions have been asked about the permanence of inkjet prints and how they compare with that of traditional silver halide color prints. This presentation will discuss accelerated light fading tests that are intended to simulate long-term display of inkjet prints under the wide range of illumination conditions found in actual indoor display environments. Reciprocity effects in high-intensity/low-intensity tests are described. The influence of relative humidity, spectral distribution of the illumination source, and other factors that may affect image stability are discussed.
