In draw-down tests the heavy load often masks the color, but even there or with a simple swab some idea of what the midtone values would be.

I had something in mind like measuring on the ink itself or printed on a 
completely neutral substrate.  And I didn't think of my Wasatch SoftRip 
that should be able to do that if I close all the other ink channels. I 
have the content of some Z3100  carts that expired before use.
The Z3200 has the heavier Chromatic Red. Will see what I can do, there's 
a longer job running on it.
