How do I assign profiles to devices?
Open System Settings ▸ Color, and click the device that you wish to add a profile to.
By clicking Add profile you can select an existing profile or import a new file.
Each device can have multiple profiles assigned to it, but only one profile can be the default profile. The default profile is used when there is no extra information to allow the profile to be chosen automatically. An example of this automatic selection would be if one profile was created for glossy paper and another plain paper.
If calibration hardware is connected the Calibrate… button will create a new profile.
