Abstract
The past decade shows a significant increase of digitally produced images. The number of output devices increased and the variety of print materials at different quality levels and with different response to environmental factors more and more substitute traditional silver-halide photography. Comparisons of the technologies become important and show possibilities as well as problems of the new methods.
This study deals with the main environmental influences causing image deterioration: light, ozone, temperature and humidity. Existing test methods have been improved to better simulate average home conditions. The results met the assumed lifetime predictions for a variety of different specimen.
