1   Scope This document provides data and information related to evaluation of image permanence of photographic colour prints in consumer home applications. This document characterizes the test methods, the end of test criteria, the environmental factors, and the reporting. It also provides the background and the history of those. This document describes guidelines and limitations for print life estimates, i.e. translation of the test results to the performance in actual usage as well as limitations of such a translation. The photographic colour prints printed digitally described in this document can be generated with dyes or pigments by several processes, including ink jet, chromogenic (silver halide), thermal dye transfer processes, and electro photography, excluding lithographic printing, screen printing and other non-digital printing.
