The Gamut View will update the shapes of the device gamuts when profiles or viewing conditions are changed.
By looking at the gamut and adjusting the controls in the AVA CMS Controller, you can see how the viewing conditions adjustments affect the results. By switching between printer profiles you can compare the available colour space on different printers and substrates.
Drag a different printer profile into the profile panel of the AVA CMS Controller and see the effect in the Gamut Window.
