Source of primary color chromaticities for ICC Prole - selects what values are used for the Primary Color
Chromaticities that are encoded in the ICC/ColorSync monitor prole. The values are used to describe the color gamut
of the display.
Options are:
• Automatic (Recommended) - the optimal setting based on the display monitor type and Target Color Gamut
selected is automatically used. It is recommended to use this setting.
• Calibration Sensor Measurements - uses the values measured by the calibration sensor. For normal color
gamut displays this is the recommended option when using a Native Color Gamut Target since the calibration
sensor can accurately measure these primary colors. For wide color gamut displays some colorimeter based
calibration sensors may not be able to accurately measure the primary colors and it is recommended to use the
Factory Measurements option.
When using a Target Color Gamut other than Native, it is recommended to use the Factory Measurements option
since the SpectraView Engine will calculate the correct primary color chromaticities, even if they lie outside of
the native color gamut of the display. Otherwise the actual measured values will be used, which may result in
an incorrect color gamut being encoded in the ICC prole since the effective color gamut of the display extends
outside the measurable color gamut.
• Factory Measurements - uses the measurements taken during production of the display monitor and data
calculated by the display’s internal SpectraView engine to encode the color gamut information in the generated
ICC Prole. These measurements may be more accurate than those of some color sensors when measuring
wide gamut displays. See “Supported Display Monitors” on page 7 for a listing of display gamut types. This
setting is recommended when using a Target Color Gamut other than Native.
