My understanding is that the Adobe color management engine that is 
what loads the ICCs and does the math is a high bit depth system.  A 
16 bit grayscale file enters the system, and a 24 bit RGB file exits 
the system to the Epson driver, if Create ICC-RGB was used to make 
the ICC.

The separation curves I use inside the ICCs serve more than just the 
functions of making the prints smoother and more neutral.  Separating 
the channels breaks up the lock-step staircase that would simply use 
the same 256 steps of the incoming file.  Each channel samples the 16 
bit incoming file differently.  By multi-sampling the incoming file, 
I think we are able to past more of the original information through 
the 8-bit/channel Epson driver.

Hope this makes some sense.
