Don't use the Cone driver with the Sepia-VM.

What I did for Piezo software users is come up with a draft formula for a
cyan-position sepia ink.  (It is not simply the VM sepia toner.)  From the
base cyan-position sepia ink, the other sepia-tone inks in the
FS/Piezo-compatible system are simple dilutions, using the MIS clear base.

Here is a draft formula for a Piezo-driver-compatible FS-Sepia,
cyan-position ink.  Once you mix this you dilute it to make the FS-Magenta
and FS-Yellow (see below).  Or, if the sepia tone is too warm for you, mix
the FS-Sepia-cyan with the standard FS cyan-position gray to get the tone
you want, and then do the dilutions below.

FS-Sepia-Cyan = 20% VM/FS-K, 26% MIS Archival magenta (color pigment), and
54% MIS FS-yellow (the new, more fade-resistant yellow pigment).

Mix an FS magenta-position ink as follows:

    26% FS cyan and 74% MIS clear base.

Mix an FS yellow-position ink as follows:

    Method 1:  Y = 11% FS cyan, remainder clear base;

    Method 2:  Y = 43% FS magenta, remainder clear base.

So, this inkset is not one that a casual user would probably be ready to
experiment with.  A willingness to mix inks is needed.

If MIS hears that there is a lot of demand for a finalized product, I'd be
happy to fine-tune the formula.  So far, I have heard no interest from MIS
in the ink.

The various users should answer this.  However, I'll add that each ink has
it's own absorption, etc. characteristics.  So, nothing is exact.  However,
the variances I measure are less than the variances I've measured in
different samples of Piezo ink.  My printers also vary, with temperature
being one of a number of apparent factors.  So, nothing is exact here, but I
think the variances are within reasonable tolerances.

Thank you for such a detailed response! You've helped me very much!
