Annotation

This International Standard describes test equipment and test procedures for determining the colour stability of photographic colour images when subjected to outdoor conditions. It does not specify limits of acceptability or failure criteria. Instead, it provides means for measuring image changes that take place during the aging of pictorial photographic images and indicates the critical image-change parameters that should be reported. Users of this International Standard should determine which test end-points best simulate the intended display application.

This International Standard is applicable to pictorial images made with digital printing media, for example:

— prints on coated papers, coated and uncoated clear and opaque films, vinyl, polyester, synthetic papers and other plastic substrates, laminated and not laminated;

— dye-based and pigment-based inkjet prints with aqueous, solvent, phase-change, or UV curing inks;

— thermal dye and mass transfer;

— dye sublimation prints;

— digitally-printed dye-diffusion-transfer prints;

— liquid- and dry-toner xerographic prints;

— liquid toner electrostatic prints;

— digitally printed images made with traditional chromogenic and silver dye-bleach photographic materials;

— colour direct thermal prints.
