Abstract

The use of high-intensity illumination to accelerate the fade of photographic prints in order to predict long-term performance under ambient illumination rests on the assumption that the Reciprocity Law is valid over the range of illumination intensities between the accelerated and ambient conditions. Simply stated, the Reciprocity Law predicts that the extent of a light-induced chemical reaction, e.g., fade of an inkjet colorant, is directly proportional to the cumulative exposure (intensity x time) independent of the illumination intensity. Reciprocity failure is said to occur when equivalent cumulative exposures at different intensities result in differing amounts of fade. In this study we investigated the reciprocity behavior of a variety of ink-media combinations in response to high- (80 klux) and low- (5.4 klux) intensity polycarbonate-filtered fluorescent illumination. We will also briefly review recent results for high- (50 klux) and low- (5.4 klux) intensity glass-filtered xenon illumination.
