Hi Rick,
You can go to this link and download two TIFF files (1st in RGB and
2nd in CMYK) which demonstrate what a RGB to CMYK Devicelink profile
can do in order to preserve specific color attributes of the original.

So if it did support RGB-to-CMYK device links, then it would be
possible to set up a conversion where you could map non-neutrals to
one normal profile, while holding neutrals to the mapping of a
Maximum GCR profile? Interesting. Can you describe more how you
would set this up, and what control it would be possible to have
for interpolating the near-neutral areas? And with what device-link
package?
I've been doing this with actions, but am not completely satisfied
with the mitigation of the near-neutral areas that don't fall
clearly into one domain or the other.

Anyone got information or detailed spec about ICC DeviceLink
profile support / compatibility with Adobe Photoshop CS4?
It seems to work only for CMYK to CMYK, not for RGB to CMYK (to
keep neutral RGB on the K plate for example).
Also, be careful to Assign the output profile (used to create the
device link) in order to get accurate preview after the conversion!
