Scope

This document describes the test equipment and test procedures for evaluating the color stability of color images in outdoor environments. It does not specify the boundaries of acceptable or failed standards. Instead, it provides a method for measuring image changes during aging and identifies the key parameters of image changes that should be reported. Users of this method can determine the test endpoints of simulation effects.
This document is applicable to images produced by digital printing media. For example: - Printed products on coated paper, coated and uncoated transparent or opaque films, vinyl, polyester, synthetic paper, and other plastic substrates; - Inkjet photos using dye-based and pigment-based inks with water-based, solvent-based, phase-change, or UV-curable inks; - Thermal dye transfer photos; - Sublimation photos; - Digital dye diffusion transfer photos; - Liquid and dry toner electrostatic printing photos; - Liquid toner electrostatic printing photos; - Digital prints produced from traditional color-developing and silver-dye fixing photographic materials; - Color thermal imaging photos.
In these digital prints, the ink layout is controlled by digital pixel information, and all settings and controls of the printing system can be recorded and repeated. In contrast, for many analog printing systems, the control of ink layer thickness can be adjusted manually. Outdoor window graphics comply with this document, while indoor window graphics, where sunlight is filtered by a layer of glass, comply with ISO 18937.
This document does not include test procedures for the physical stability of images, substrates, or mounting materials. However, in some cases, physical changes in materials (such as substrate brittleness, image layer cracking, or image layer separation from the substrate) will determine the lifespan of photo materials, rather than image stability.
Note: Image print stability results are dete
