Abstract

Continuing research into last year's proposal for a new test method to improve the dark storage test of print images has led to further improvement in the sandwich method. Based on feedback, several additional test materials were investigated, with the most promising candidate being a clear polyester film. This material was most effective in preventing cross contamination between samples and in eliminating the influence of airflow. This research is part of ongoing work contributing to the development of standardized test methods for image permanence.
