Image Engineering printer and print life tests white paper
The past decade shows a significant increase of digitally produced images by both professionals and consumers. 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.
The need for adequate test methods is the reason why ISO technical committee 42 is currently working on a revision of the Image stability test described in ISO Standard 18909 ('Photography-Processed photographic color films and paper prints- Methods for measuring image stability'). Image Engineering is now participating in the development of the standards which address this issue.
