- Scope
- This International Standard describes test equipment and procedures for measuring the light stability of images of colour photographic reflection prints designed for display in, for example, houses, apartments, other dwelling places, offices and commercial display, when subjected to certain illuminants at specified temperatures and relative humidities. This International Standard also addresses colour photographic reflection prints designed for display in galleries and museums. Indoor illumination conditions described in this International Standard include a) simulated indoor daylight typical home display, b) simulated direct sunlight in-window display, c) fluorescent illumination using “cool white”, and d) other types of illumination sources, such as other fluorescent lamps, tungsten halogen, LED, OLED and metal halide lamps. This International Standard is applicable to reflection colour prints made with colour hardcopy materials. Included are inkjet prints, thermal dye diffusion transfer (“dye-sub”) prints, liquid- and dry-toner electrophotographic prints, prints made with traditional chromogenic (“silver-halide”) photographic colour materials and, in general, all types of colour prints made with direct analog and digital print processes. The recommended evaluation methods can also be applied to black-and-white photographic prints. This International Standard does not include test procedures for determining the effects of light exposure on the physical stability of images, supports or binder materials. However, it is recognized that in some instances, physical degradation, such as support embrittlement, image layer cracking or delamination of an image layer from its support, rather than the stability of the image itself, will determine the useful life of a print material. Print image stability results determined for one printer model, software settings, colourant and media combination might not be applicable to image prints produced through another printer model, software settings, colourant and media combination.
