QTR-Quadtone RIP

At last I think I've realised my problem.  EEM can't handle the volume
of ink that the Cone curves put down at 2880.  Even in the midtones
there's a fair bit of overlap between the cartridges, and the volume
of ink that the curves put down to achieve the tone is more than the
paper can handle.

I wonder if it's possible to tweak these curves for 1440, or whether
the same problem will occur there.  Perhaps the traditional QTR
approach with limited curve overlap might be the only way for EEM.  

(I know that K7 might seem overkill for EEM, but it's useful for some
purposes.)
