This document describes test equipment and procedures for measuring the light stability of colour photographic reflection prints designed for display, when subjected to a filtered xenon-arc light source simulating daylight through windows at specified temperatures and relative humidity.<\/p>\n
This document is applicable to photographic reflection prints, made with analogue and digital print processes. The recommended test methods can be applied to both colour and black-and-white photographic prints.<\/p>\n
This test method assesses colour and density change.<\/p>\n
