ICCprofil

ICCProfil refers to the concept of an ICC profile, a standardized data set created by the International Color Consortium to describe the color characteristics of a device or color space. An ICC profile enables color management systems to translate colors between different devices and spaces in a device-independent way, typically via a Profile Connection Space based on CIE XYZ or CIE Lab.

An ICC profile is a binary file with a header that identifies the profile class (input, display, output, or device link), the color space, and the profile connection space. It also contains a tag table that lists various tags describing device characteristics and color transformations. Common tags include descriptions of the profile, chromaticity coordinates (for primary colors), matrix data or tone curves (TRCs) for color channels, and color transformation data. The combination of these elements allows a color management system to map colors from one device space to another.

Profiles can be embedded in image files or distributed separately. A color management system uses profiles to convert colors from a source device space to the PCS, and then from the PCS to the destination device space, guided by rendering intents such as perceptual, relative colorimetric, absolute colorimetric, or saturation.

Types of profiles include input (source) profiles that describe how a device captures color, display profiles for monitors, and output profiles for printers or other output devices. Device link profiles map directly between two device spaces for efficiency. ICCProfil and its standards underpin color-consistent workflows in photography, publishing, and digital imaging, with ISO/IEC 15076-1 formalizing the specification.
