Описание (английский):

This document describes procedures for evaluating the accuracy of colorimetric rendering intents in ICC profiles. It applies to v4 ICC profiles made according to ISO 15076-1. It does not apply to subjective tests of ICC profiles, such as for perceptual or saturation rendering intents, and it does not apply to high dynamic range colour media or spaces.

Abstract

Overview

ISO/TS 23564:2020 specifies procedures for evaluating the colourimetric accuracy of ICC v4 profiles (as defined in ISO 15076-1). The technical specification focuses on objective tests for colour transform accuracy of colorimetric rendering intents (media-relative / ICC-Absolute), describing how to quantify forward and inverse model performance in ICC profiles. It does not cover subjective tests (perceptual or saturation rendering intents) or high dynamic range (HDR) colour media/spaces.

Key topics and requirements

Profile evaluation tests: Two main test classes:
- Round trip tests - verify inversion accuracy when converting PCS → device encoding → PCS using BToA1Tag and AToB1Tag.
- Device model tests - assess forward/inverse model accuracy for predicting device colourimetry from encoding values (and vice versa).
Tags and models:
- Forward model encoded in AToB1Tag; inverse in BToA1Tag.
- Use chromaticAdaptationTag to convert between measurement illuminants and PCS (D50) when required.
Test data and metrics:
- Use test images (e.g., ISO 12642-2) and additional application-specific colour subsets (neutrals, skin tones).
- Report colour differences as median, maximum and 95th percentile ΔE00, with PCSLAB scaled to ICC‑Absolute colourimetry.
- Typical round-trip results: **median ΔE00
