RE: [Digital BW] ink positions in variable mix quadtones (Hex set)

Kees,

Yes, the dark and light grays are the same between the hextone and quadtone
versions of the inksets.  (Of course, the inks in the UT inkset are
different than those in the VM inkset, although the densities are
approximately the same.)

You'll need different curves to smooth the tones.  The 3-gray setup would
not, for example, be the same as the Piezo/FS setup.  The cyan is the same
density, but the VM/UT medium and light grays are darker than the Piezo/FS
medium and light grays.

>I allready have the black(s) and two greys from the UT quad set.

The light cyan is the one that is missing.

>Are the three greys in the UT hex set 75%-50%-25% dilutions like the

Be aware that MIS uses "75%-50%-25%" as relative designations.  Those are
not the true dilutions.

I'm not sure what MIS is doing, but I'd assume the "75%" is the UT cyan, the
"50%" is the UT light cyan, and the "25%" the UT hex yellow/quad magenta.
