Effect of Temperature and Humidity on Rate of Image Fading in Ozone

Abstract

The digital print industry is working toward the goal of adopting improved test methods for image permanence. As part of this effort, the new test methods are being designed to isolate the environmental variables that impact image permanence. The benefits of this approach are that it simplifies the test method and test equipment while promoting test results that can be reproduced at other test laboratories. This study focused on the impact of varying the temperature and humidity during ozone stability tests while keeping all other known variables constant. The data is useful for evaluating acceptable tolerances for temperature and humidity to achieve consistent results during an ozone stability test. This research is part of ongoing work contributing to the development of standardized test methods for image permanence.
