ICC Specifications

The current iccMAX specification was approved by the ICC on 13 November 2019.

Specification ICC.2:2019 (iccMAX) Image technology colour management - Extensions to architecture, profile format, and data structure

This specification 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 use case-specific Interoperability Conformance Specifications. More information about iccMAX is available on the iccMAX page.

v4 ICC Specification
This version is technically identical to ISO 15076-1:2010, which is available from ISO. This is the most widely used version, first published in 2001.

Specification ICC.1:2010-12 (Profile version Image technology colour management - Architecture, profile format, and data structure

The document should be read in conjunction with the current Errata list to ICC.1:2010-12. This list of errata is updated when errors in the specification are notified to the ICC Technical Secretary.
