This document specifies a set of standard large gamut colour images (encoded as 16-bit CIELAB digital data) that can be used for the evaluation of changes in image quality during coding, image processing (including transformation, compression and decompression), displaying on a colour monitor and printing. These images can be used for research, testing and assessing of output systems such as printers, colour management systems and colour profiles.d edition 2022-08 Graphic technology — Prepress digital data exchange — Part 3: CIELAB standard colour image data (CIELAB/SCID) Technologie graphique — échange de données numériques de préimpression — Partie 3: Données d'images en couleur normalisées CIELAB (CIELAB/ SCID) Reference number ISO 12640-3:2022(E) ？ ISO 2022 ISO 12640-3:2022(E) COPYRIGHT PROTECTED DOCUMENT ？ ISO
