Abstract
Gas resistance is an important element in image permanence. We studied the effects of O3, NO2 and SO2 exposure on several imaging materials, such as inkjet, silver halide and other printing materials and observed the fading of those imaging materials under actual indoor display conditions. We found that a correlation exists between image deterioration in the actual display and the accelerated gas exposure test and identified problems in the mixed-gas tests, including, for example, a rapid reaction between O3 and NO2 under accelerated conditions. We will discuss the effects of this reaction on the estimation of print life.
