Imaging materials — Reflection colour photographic prints — Method for testing humidity fastness

This document describes test methods for evaluating reflection colour photographic prints with regard to changes in image appearance resulting from exposure to high relative humidity. NOTE Testing under low humidity conditions is described in ISO 18949. The observed changes relate to colour, tone and loss of sharpness caused by horizontal and vertical diffusion of colorants from exposure to elevated humidity levels. Other humidity-related factors, such as mould and mildew growth, and physical damage, such as curl, cockle, cracking or delamination due to humidity cycling, are outside the scope of this test method. Although the method and procedures described in this document can be used to test any colour hardcopy technology, it is particularly appropriate to systems where the colorants are applied by a mechanism involving the diffusion of colorant into image-receiving layers (for example inkjet or dye diffusion processes) or applied onto uncoated fibrous materials such as paper.

Imaging materials — Image permanence specification of reflection photographic prints for indoor applications — Part 1: Test methods

This document specifies the test methods, the test conditions, the test target design, and the analysis procedures for the evaluation of the image permanence performance of digital photographic reflection prints. Tests based on ISO 18936, ISO 18937 (all parts), ISO 18941, and ISO 18946 characterize the thermal stability, the light stability, the ozone stability, and the humidity stability of photographic prints. This document is applicable to any digital photographic reflection print, which includes prints created by chromogenic silver halide, inkjet, electrophotography, thermal diffusion, and others. Black and white prints composed of metallic silver are not within the scope, but monochrome prints where the printing process contains dyes are within the scope. The document specifies the content and procedure for graphical reporting of test results as a first level data collection for basic technical communication of image permanence performance of photographic prints. Application-specific end-points, environmental conditions and test doses (durations, intensity) are not included in this document.

Imaging materials — Methods for measuring indoor light stability of photographic prints — Part 1: General guidance and requirements

This document provides information and general guidance about the methods for measuring the indoor light stability of reflection prints, both colour and monochrome, transparent or translucent films, and photographic prints for backlit displays. This document is relevant to the selection and operation of the methods of exposure to radiation and environmental stress factors described in detail in subsequent parts. It also describes general performance requirements for devices used for exposing printed material to laboratory light sources. Information regarding performance requirements is for producers of artificial accelerated lightfastness devices. NOTE In this document, the term “light source” refers to radiation sources that emit UV radiation, visible radiation, infrared radiation, or any combination of these types of radiation. This document 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, determines the useful life of a print material. Print image stability results determined for one printer model, software settings, colorant, and media combination may not be applicable to another combination.

Imaging materials — Methods for measuring indoor light stability of photographic prints — Part 2: Xenon‐arc lamp exposure

This document describes test equipment and procedures for measuring the light stability of photographic prints when subjected to a filtered xenon-arc light source at specified levels of illuminance (irradiance), temperature and relative humidity. It is applicable to both colour and monochrome reflection prints, transparent films, or translucent films. It is also applicable to photographic prints in general, photobooks, or prints for backlit displays. General indoor display conditions described herein are intended to simulate common use conditions found in houses, apartments and other dwelling places where indirect lighting due to filtering (through window glass) and shading is often the principal illumination causing displayed photographs to fade. Simulated in-window display conditions are intended to simulate terrestrial daylight transmitted through standard architectural window glass (double glazing). A typical example of such display can be found when images are displayed in store windows, facing toward the outdoors, so that they can be viewed by people outside of the store[5][6]. NOTE 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. General guidance is given in ISO 18937-1.

Permanence and durability of commercial prints — Part 22: Backlit display in indoor or shaded outdoor conditions — Light stability

This document describes the test methods for light stability measurements of prints on transparent or translucent foils, sheets and paper or printed on a textile, which are displayed on backlit units installed in indoor or in shaded outdoor conditions, which are protected against direct precipitation and radiative heating. Installations of backlit display units in outdoor areas without shading, which are exposed to direct weathering and/or radiative heating, are excluded. This document is applicable to the various product classes of “commercial prints” that are suitable for backlit display. These commercial prints often contain combinations of text, pictorial images and/or artwork. This document provides guidelines for colour measurements, data analysis and also provides guidance for translation of test results into suitable image permanence performance claims considering the variability of backlit designs and environmental conditions. This document is applicable to both analogue and digitally printed matter. Methods and principles apply to both, colour, and monochrome prints.

Photography — Processed photographic colour films and paper prints — Methods for measuring image stability
SIST ISO 18909:2023

This document describes test methods for determining the long-term dark storage stability of colour photographic images and the colour stability of such images when subjected to certain illuminants at specified temperatures and relative humidities. This document is applicable to colour photographic images made with traditional, continuous-tone photographic materials with images formed with dyes. These images are generated with chromogenic, silver dye-bleach, dye transfer, and dye-diffusion-transfer instant systems. The tests have not been verified for evaluating the stability of colour images produced with dry- and liquid-toner electrophotography, thermal dye transfer (sometimes called dye sublimation), ink jet, pigment-gelatin systems, offset lithography, gravure and related colour imaging systems. If these reflection print materials, including silver halide (chromogenic), are digitally printed, refer to ISO 18936, ISO 18941, ISO 18946, and ISO 18949 for dark stability tests, and the ISO 18937 series for light stability tests. This document does not include test procedures for the physical stability of images, supports or binder materials. However, it is recognized that in some instances, physical degradation such as support embrittlement, emulsion cracking or delamination of an image layer from its support, rather than image stability, will determine the useful life of a colour film or print material.
