Inkjet photographic prints, especially those printed with dye-based inks on porous media, are subject to rapid dye fading when exposed to ambient levels of ozone. The rate of fade is much slower with dye-based inks on swellable media and, in general, with pigment-based inks. As part of an ongoing effort to establish a standardized test method to accelerate the rate of ozone-induced fade, we have been exploring the use of high concentrations of ozone under controlled conditions. A key assumption, necessary to estimate the corresponding rate of fade at much lower, ambient levels of ozone, is that there is a reciprocal relationship between ozone concentration and time of exposure. In this presentation, we will provide an update on our previous report of various ink-media combinations with respect to ozone reciprocity effects.
