This document specifies test method, test target, and reporting requirements to determine the scratch resistance of prints with photographic images. Photographic images can be produced by a wide range of printing technologies, including silver halide, electrophotography, inkjet, dye diffusion thermal transfer, commonly known as dye sublimation, and dye transfer processes. This document is applicable to prints with paper substrate and other type of substrates including prints on plastic, glass, metal and other materials. This document is applicable to photographic prints that have no protection as well as photographic prints that are protected by a coating or lamination. It is not the purpose of this document to define limits of acceptability or failure. They would be determined by the user and the intended application.
Abstract
Overview
ISO 18951-1:2022 - Imaging materials - Scratch resistance of photographic prints - Part 1: General test method - defines a standardized approach to assess the scratch resistance of photographic prints. The document sets out the test target, general test method, sample preparation, conditioning, evaluation and reporting requirements for prints produced by a wide range of technologies (silver halide, electrophotography, inkjet, dye‑sublimation, dye transfer) and on diverse substrates (paper, plastic, glass, metal). It applies to both unprotected prints and those with coatings or laminations. The standard provides guidance for reproducible testing but does not prescribe acceptance limits - those are left to users and intended applications.
Key topics and technical requirements
- Test principle: A stylus is moved across the print under controlled load and speed to introduce localized stresses (indentation, friction) and produce damage. Results are characterized by a critical load (minimum load producing a defined damage level).
- Stylus classification: Defines scratch scales by stylus size - nano (
