Set gamut mapping

An output profile contains information for different types of gamut compression with different rendering intents. Rendering intent settings control how gamut mapping occurs.

The Edit Gamut Mapping window displays the colormetric mapping, saturation blending, and perceptual mapping used for gamut mapping. These settings apply to both RGB and CMYK profiles.

The default settings for the gamut mapping options are recommended for most profiles.

  • Colorimetric mapping applies to the Absolute Colorimetric and Relative Colorimetric rendering intents. It determines how an output color is matched to a source color.

  • Saturation blending applies to the Presentation rendering intent.

  • Perceptual mapping applies to the Photographic rendering intent.

  1. In the Apply settings window, click Edit Gamut Mapping.
  2. Click one of the following in the Colorimetric Mapping list:

    • Closest dE (closest numerical match) - Sets the output color value that is closest to the source color value numerically in units of dE 76. This setting generally produces the most visually appealing color.

    • Closest dE Enhanced Shadows (for restricted gamuts) - Sets the output color value that is closest to the source color value numerically, except that it adjusts color values in shadow regions to provide smoother gradations. This setting may enhance results when profiling on media with a small gamut.

    • Constant hue (sometimes more visually pleasing) - Sets the output color value closest to the source color value in the same hue. This setting might produce more desirable output than Closest dE (closest numerical match). For example, a blend from pure white to pure blue is smoother with this setting. Photographic images with a wide range of sky blue tones also reproduce better.

    • Closest dE 2000 (closest numerical match) - Sets the output color value that is closest to the source color value numerically in units of dE 2000. This setting generally produces the most visually appealing color.
  3. Click one of the following in the Saturation Blending list:

    • Enhance Gamut Blending (smoother transitions) - Generates smooth transitions through the entire gamut, making larger adjustments for colors farther from the neutral axis.

    • Use Presentation Method from EFI Profiler 1.5 - Preserves continuity if you have used EFI Color Profiler v1.5 to create profiles and want to match the profile you are creating now with your existing profiles.

    • CIECAM saturation - Produces more natural colors when using the Presentation rendering intent, based on the latest CIE color appearance model.

  4. Click one of the following in the Perceptual Mapping list:

    • EFI photographic (Match Fiery workflows) - Matches Fiery workflows.

    • Perceptual (ICC standard) - Standard ICC mapping.

    • CIECAM presentation - Produces more natural colors when using the Photographic rendering intent, based on the latest CIE color appearance model.
