This set up is for the 2200 so I guess the assignments are different. I 
should emphasise that this was only a technical exercise. My imitation 
of the pre-made cone curves is not perfect but the .acv's can be tweaked 
  in theory to exactly replicate those curves. They can also be 
linearised subject to the provisos that Roy mentioned.

In practical reality doing this sort of thing with a quadtone set up is 
probably more realistic as dead spots and non-linearities are less 
likely to occur (although still a possibility) and are easier to cure 
than with the larger number of inks.

In my brief experience with the Bowhaus RIP this is how things work 
except Bowhaus has it's own Curves editor where you can add points to 
the curve like the Curves facility in photoshop.
