Device Profile - Detailed information about color qualities in a device, also referred to as profile and ICC profile.
Device-independent
Describes a colour space that can be defined using the full gamut of human vision, as defined by a standard observer, independent of the colour- rendering capabilities of any specific device.
Device-independent spaces express color in absolute terms. These often serve as universal reference colors, so they're useful as a backdrop for comparing other devices.
PDF files are most appropriately used to encode the exact look of a document in a device-independent way.
