Digital BW, The Print

Updating my experiments with dilute HP PK, the bottom line is that 
it's working fine so far.  

I've tried a number of different bases -- buffered and complex as 
well as the simple C6 base (see http://www.paulroark.com/BW-Info/Ink-
Mixing.pdf ).  Frankly, I'm not sure the more complex ones are worth 
the effort, although 1% Edwal LFN wetting agent will be needed for 
1.5 picoliter printers.

The C6 base is working best for the 50% dilution, in part, because 
on, for example, Crane Silver Rag even the 50% dilution prints with a 
dmax of 2.19.  So, while a true PK will do better, it's not going to 
be worth my time or money to bother with one.

Currently I have the HP-C6 in a 220.  The Y position is MIS LLK, and 
the K position is Eboni.  The 4 dilutions of HP PK are 50%, 20%, 10%, 
and 5%.  It prints with either the Epson driver or QTR, on matte or 
glossy paper. 

The tone with the Epson driver and no curves is relatively neutral, 
with the MIS LLK offsetting the too-cool (for me) HP PK native tone. 

So far so good.
