--- Dye-based and pigment-based inkjet printing of photographs using water-based, solvent-based, phase-change or ultraviolet (UV) curable inks; ---Thermal imaging dye transfer photos; ---Sublimation photos; ---Digitally printed dye diffusion transfer photos; ---Liquid and dry toner electrostatic printing photos; ---Liquid toner electrostatic printing photos; ---Digital prints made from traditional chromogenic and silver dye-fixed photographic materials; ---Color thermal imaging photos: In these digital prints, the layout of ink is controlled by digital pixel information, and all the printing system's There are settings and controls: In contrast, with many analog printing systems, the control of the ink layer thickness can be adjusted manually: Outdoor The window graphics for indoor spaces, where sunlight is filtered by a layer of glass, comply with ISO 18937: This document does not include procedures for testing the physical stability of images, supports, or binding materials: However, in some cases, Stability, some physical changes of materials (such as support body becomes brittle, image layer cracks, or image layer falls off from support body, etc:) will determine the stability of photo materials: The service life of the material: Note: Image print stability results are determined by the printer model, ink set, print mode, print resolution, and media combination: and/or media, and are not intended for images produced with other printer models, ink sets, print modes, print resolutions, and media combinations:2 Normative referencesThe contents of the following documents constitute the essential clauses of this document through normative references in this document: For referenced documents without a date, only the version corresponding to that date applies to this document;
