Digital BW, The Print

By the way, this is the latest ink base mix I've made.

I recommend staying with what MIS will make available, but this one 
appears to work and is totally open source.  

It's a good exercise to explore these alternatives.  The substances and 
basic knowhow are available, and most old darkroom workers would be 
comfortable doing this.  On the other hand, how much benefit can come 
from fine tuning a base to a specific matte paper is uncertain. As with 
my previous experiences with custom mixing of film developers, when 
Kodak or other company came out with a good, pre-mixed solution, I used 
it.  (Anyone want my old ingredients to mix POTA developer?)

Frankly, matte papers printed with older printers are easy to deal 
with.  The more serious work here is going into trying to cure glossy 
substrate artifacts and dealing with increasingly fast printing speeds 
with smaller nozzles.

Of course, the most interesting thing I ran into is the inkjet printing 
of carbon nanotubes for various purposes.  Even totally new types of 
heads that can work faster and with smaller droplets have been 
developed.  But nanotubes actually appear to be able to be printed with 
Epson printers using a base similar to the one outlined above.
