Really it has to do with how the inks are mixed. If the printer 
(hardware or driver) does not mix those 8 channels down into the 
standard 4 (CMYK), then you need a special multi-channel profile. 
Those have been available for years. Monaco Profiler and GMB Profile 
Maker Pro can both make multi-channel profiles (if you buy the 
highest version $$$$). These are commonly called HiFi printers when 
using CMYK and RGBO or any other non primary color, and they have 
been around for many years (Colorspan, Roland, Mimaki, etc.)

If you want real control for normal CMYK printing, then you need a 
RIP that allows you to customize where and how the channels get 
mixed. After that it is simply a matter of CMYK profiles again.

Since the most recent info has them as being CcMmYKklk, these might 
not be considered as HiFi printers, as there are still only 4 color 
channels. With a good RIP, it sounds as if you could change some of 
the colors over to any of RGBO, and drive it in multi channel mode 
with multi channel profiles.
