This study compares the fading of inkjet prints tested in environmental chambers using either an electrostatic discharge or ultraviolet radiation to produce ozone. Our results indicate that over the range of 0.1 to 5.0 ppm ozone in air, very similar fading characteristics are obtained at 50% RH with the microporous and swellable polymer based inkjet papers tested, whether ozone is produced with an electric discharge or with a UV radiation source. Reciprocity between ozone concentration and time is observed for the fading of dye-based inkjet images printed on microporous papers. In addition, results from the accelerated ozone fading tests are compared with fading under “real world” ambient indoor air conditions.
