Digital BW, The Print

Dario,

Even my old 7500 looks OK at display print size with only 5 carbons 
firing.  So, in an k2 printer, you'd almost certainly have the 
smoothness you need with only 5K.

I have not loaded a printer with the C6 base carbons in addition to 
MIS or Epson LC and LM.  On the other hand, in anticipation of this 
very issue, I've had a test tube mix of Epson UC M highly diluted in 
the C6, generic base for 2 months, and it looks perfect.  I favor 
Epson M over MIS M.  So, diluting UC M with the C6 base is where I 
was intending to go with this approach, and so far, I've seen no 
evidence of incompatibility.  

(Note that MIS warns that the Eboni-6 inks are not compatible with UC 
inks, but it's the commercial dilution base that is the problem.  The 
C6 base is different.)  

While my test tube experiment is not a guarantee that there will be 
no problems, I've seen strange results and very fast settling of UC M 
and other pigments in some other bases.  In short, my best guess is 
that we can buy UC M in 7600 carts and dilute it with C6 base to get 
an economical LM.  The usual dilution for LM is 30% M to 70% base.  A 
higher dilution would be smoother.

Let us know how it works if you give it a try.
