introduction

A photo album is a book made up of pages of photos, illustrations and text, usually designed by professionals for a specific group of people. Like photographs, photo albums are produced for a wide range of purposes, from large commercial installations to disposable household items, and their longevity is expected. Durability and durability can cover an equally wide range, so the materials used in making the album need to be carefully considered to ensure that the images[33] and the album itself are High durability of the body[34]. Photo albums are usually stored in closed conditions, either stacked together or on shelves; therefore, there may be Environmental factors that may adversely affect the photos, such as light and ozone, may not be suitable for the preservation of the pages in the album. Users should be aware that if the album displays or otherwise exposed to prolonged exposure to light or other environmental factors that may affect the permanence and durability of the album. ISO 18937 (all parts) and ISO 18941 provide guidance for testing the effects of light and ozone on photographic albums. The test methods contained in this document assume that the albums may be stored and used in either a controlled or uncontrolled atmosphere. For this reason, this document includes test conditions for evaluating the adverse effects of humidity and temperature that may exceed Recommended long-term and medium-term storage conditions are described in ISO 18920.This also includes conditions designed to simulate the short-term exposure of albums to high temperatures inside the vehicle. Temperature environment test conditions. This document contains many specific tests for various binding systems and printing processes. This document is not intended to require that all possible combinations be tested. Because the number of combinations is so large, it is not possible to test all combinations of size, cover material, binding options, and printing processes. However, testing is encouraged. Representative material combinations. Photo album of imaging materials Test methods for persistence and durability

1 Scope

This document describes test methods for evaluating the permanence and durability of photographic albums, including covers and pages. This document applies to albums of reflective color photographs produced on all types of color hard copy materials, including those from traditional analog photographic processes. Regardless of the printing process, the same performance test method applies. The number of combinations of materials, binding options, and printing processes is so large that this document does not include testing of all possible combinations. Instead, it tests the Representative photo pages, cover materials, and binding options used in the work.
