In principle Device N colorspace is the natural way to make the
underlying multichannel colorspace available for characterization.
This will probably be the case until the application writers and other
users inevitably misuse the facility (as they have done in the past with
device colorspaces and separation colorspaces), forcing the RIP vendors to
disconnect Device N from the underlying device, and emulate user and application
writers assumed Device N behavior. This is exactly what has happened already with
the Altona Test suite - the writers of the test suite assume that they are
talking to a native CMYK device, and that therefore Device N maps directly
to CMYK, even though this is a device dependent feature. Anyone wishing to
print the Altona test suite therefore needs to emulate the behavior of a CMYK
device (including Device N mapping to CMYK), thereby forcing direct access to
the underlying multichannel device characteristic to use some other (non-standard)
mechanism.
