What is ISO-CIE 19476:2021?

ISO-CIE 19476:2021 is an international standard that specifies colorimetric data for transmissive, reflective, and emissive imaging media. This technical article aims to provide a thorough understanding of ISO-CIE 19476:2021 and its significance in the field of color management.

The Importance of Colorimetric Data

Colorimetric data plays a crucial role in various industries such as printing, photography, graphic design, and display manufacturing. It enables accurate color reproduction across different devices and mediums, ensuring consistency and fidelity in visual representation. ISO-CIE 19476:2021 provides a standardized framework for capturing and managing colorimetric data, allowing professionals to achieve reliable and predictable color outcomes.

Key Features of ISO-CIE 19476:2021

ISO-CIE 19476:2021 defines spectral data formats and measurement conditions necessary for assessing colorimetric properties of imaging media. It outlines procedures for measuring and calculating colorimetric values, including color appearance attributes, spectral tristimulus values, and chromaticity coordinates. The standard also specifies the use of reference illuminants and observer functions, which are essential for accurate color evaluation.

Furthermore, ISO-CIE 19476:2021 introduces an extended set of simple metameric indices, which enable the detection of potential metamerism issues. Metamerism refers to the phenomenon where two samples appear to match under certain lighting conditions but exhibit a noticeable color difference under different lighting. By utilizing these indices, organizations can minimize metamerism-related challenges and ensure reliable color reproduction in diverse viewing environments.

Benefits and Applications

Implementing ISO-CIE 19476:2021 brings several benefits to various industries.
