The test strips were "black ink only" Epson driver prints.  So, the
differences are not accounted for by driver differences.

It sounds like there would probably be no problem in using the VM/FS-K with
the PT midtones -- at least from a chemical compatibility perspective.  I
think that the densities of the inks may make the ramp less linear.
