Effect of Airflow on Rate of Paper Yellowing in Dark Storage Test Conditions

摘要

It is well known that inkjet photographic prints can be susceptible to fading due to environmental factors such as light, ozone, humidity, and temperature; moreover, that these environmental factors interact differently depending on the ink and paper chemistry. Image permanence test methods typically involve separate image permanence evaluations for each environmental factor by imposing strict requirements on the non-active factors present in each test setup. This approach is necessary because the impacts of combining several such environmental effects together in a storage environment are difficult to control and model in a repeatable way. As a part of defining the required test conditions, it is necessary to correctly identify and constrain each environmental factor that can impact test results. In particular, this study probes the interacting effects of temperature and airflow on inkjet microporous photo paper samples, and the ways in which these interactions can impact image permanence evaluation of prints for dark (photo album) storage conditions. This research has been conducted as a contribution to the developing ISO standardized test method for image permanence applicable to consumer dark storage conditions.
