Nosaukums<p>This International Standard describes test equipment and test procedures for determining the colour stability of</p> <p>photographic colour images when subjected to outdoor conditions. It does not specify limits of acceptability or</p> <p>failure criteria. Instead, it provides means for measuring image changes that take place during the aging of pictorial</p> <p>photographic images and indicates the critical image-change parameters that should be reported. Users of this</p> <p>International Standard should determine which test end-points best simulate the intended display application.</p> <p>This International Standard is applicable to pictorial images made with digital printing media, for example:</p> <p>— prints on coated papers, coated and uncoated clear and opaque films, vinyl, polyester, synthetic papers</p> <p>and other plastic substrates, laminated and not laminated;</p> <p>— dye-based and pigment-based inkjet prints with aqueous, solvent, phase-change, or UV curing inks;</p> <p>— thermal dye and mass transfer;</p> <p>— dye sublimation prints;</p> <p>— digitally-printed dye-diffusion-transfer prints;</p> <p>— liquid- and dry-toner xerographic prints;</p> <p>— liquid toner electrostatic prints;</p> <p>— digitally printed images made with traditional chromogenic and silver dye-bleach photographic materials;</p> <p>— colour direct thermal prints.</p> <p>In these digital printing processes, the ink laydown is controlled by means of digital pixel information, and all</p> <p>of the settings and controls of the printing system can be documented and repeated. In contrast, for many</p> <p>analogue printing systems, the control over the ink film thickness can be subject to manual adjustment. Window</p> <p>graphics on the outside of windows are covered by this International Standard. Window graphics on the inside</p> <p>of windows, for which sunlight is filtered by a layer of glass, will be covered by ISO 18937.</p> <p>This International Standard does not include test procedures for physical stability of images, supports or</p> <p>binder materials. However, it is recognized that in some instances physical degradation such as support</p> <p>embrittlement, image layer cracking, or delamination of an image layer from its support, rather than image</p> <p>stability, will determine the useful life of a print material.</p> <p>NOTE Image print stability results determined for one printer model, ink set, printing mode, print resolution and</p> <p>media combination are not applicable to image prints produced through another printer model, ink set, printing mode, print</p> <p>resolution and media combination, even if the ink jet cartridges and/or media used in testing are the same.</p>
