FOOTNOTE IMAGE LONGEVITY To test the image permanence of prints that are stored in an album, we use an accelerated testing method similar to how the image permanence of silver-halide photo papers are measured when stored in dark places. Print samples are printed with the optical density of 1.0 (each Bk, C, M,Y). The samples are kept in a certain environment of high temperature and 50% humidity. The rate of the decrease in the optical density and rate of yellow discoloration are recorded. The recorded results are then converted to the length of time when print image is kept in an environment of 23℃/ 50% humidity. 'The point where monochromatic/ reflective optical density shows loss of 30% (starting density of 1.0).
