sRGB Appearance profile beta

An sRGB Appearance profile has been developed by Fuji-Xerox and tested internally by ICC. The profile is now being released in beta for public testing.

This profile is a v4 replacement for commonly used sRGB v2 profiles. It gives better results in workflows that implement the ICC v4 specification, and is intended to be used in combination with other ICC v4 profiles.

The ICC specification allows there to be more than one Perceptual Rendering from a given source colour space. For sRGB, ICC provides the Preference and Appearance profiles, both of which provide standard color transforms from sRGB to the perceptual reference medium gamut (PRMG). These two color profiles can be thought of as re-targeting and re-purposing as described in ICC White Paper 02. The difference between these two profiles is in the Perceptual Rendering; other Rendering Intents are the same. A full description and intended use for the sRGB v4 ICC preference profile is described in ICC White Paper 26.

The features of the Appearance Profile are that it:

• May be used as re-targeting in perceptual rendering intent.
• Produces more color-consistent results in color reproduction on display.
• Produces more pleasing results in appearance and tone scaling for most images than Colorimetric Rendering.

The Appearance profile is particularly recommended when the difference between source gamut and destination gamut is large and it is desired to 're-purpose' the image (i.e. make it optimal for the reproduction medium - see ICC White Papers 1 and 2 for more on re-purposing and re-targeting of color).

For more information on the ICC sRGB Appearance Profile, please see ICC White Paper 42.
