I assume the friend was not using UT1 in a 2100.  That printer can use UT7,
but not the original UT (aka UT1).

I'm confused also.  The "UT-Hex-4-Y" label, I believe, should have been the
same as the original UT Y that you were using.

It may be easiest to just start over -- if you have the time.

Don't use Eboni.

LC in the UT1 inkset is 50% C.  So, LC is the best starting point due to it
having the correct base.  

> Isn't the base 4:3  H2O/glycerine?

No.  That is just a simple base I made that would hold most of the pigs
(even Eboni) in suspension.  The UC inks were my main target for it.  It is
missing some components.  If not much is used, it's probably not a problem.
However, if most of the base is this simple mix, I don't know what the
effects would be.  I've used up to a 50% mix of it, but that's as far as
I've gone.

The UT1 Hex Y is about 22% UT1-Hex-LC and 78% base.  So, using the
simplified base to that degree is beyond what I've tried.  

Good luck.
