Investigation into ozone testing has shown that print samples may be subject to ozone reciprocity failure. Many print samples in accelerated ozone testing fade faster at lower ozone concentrations in comparison to fade rates in tests run at higher concentrations to the same cumulative ozone exposures. In contrast to this trend, samples often faded more slowly in ambient air compared to the accelerated tests. Separate research had shown that ozone test results are sensitive to dry time, with longer drying typically improving image stability. This has implications for testing in ambient air, because the effective dry time of the print samples is increased due to the length of the test. This study focused on understanding how dry time may interact with ozone reciprocity failure and thereby explain the contrary trends observed.
