ICC Specifications


The current iccMAX specification was approved by the ICC on 12 October 2023.

Specification ICC.2:2023 (iccMAX) Image technology colour management - Extensions to architecture, profile format, and data structure

The previous version, ICC.2:2019, is also published as ISO 20677-1. The ISO document is the responsibility of ISO TC 130 Joint Working Group 7, together with ICC.

The ICC and ISO versions are effectively identical, with the exception of differences in title page, copyright statement etc.

The iccMAX specification should be read in conjunction with the current Errata list and with use case-specific Interoperability Conformance Specifications. More information about iccMAX is available on the iccMAX page.

This is the latest update to the v4 specification, published May 2022. It incorporates three additional tags or types approved by ICC ballot since the last version, ICC.1:2010, together with items from the published errata and other minor changes. The new tags and types are:
