Digital BW, The Print

I am not ready to go back to the darkroom (yet) but using the 
various quad inksets that are available seem a little like the 
fellow that was hitting his head on the wall because it felt so good 
when he stopped.

Just for fun I tried printing some tritones and quadtones using 
photoshop, a Canon S9000, fotonic inks and Lyson photomatte. The 
reasult were not all that displeasing. What I rapidly found out is 
than my knowledge of using and manipulating duotones is at best 
rudimentary and I would be greatful for any suggestions on a 
reference(s) for using them in photoshop.

If these experiments work as well as I hope then I think the next 
step will be an Epson 2200 or perhaps a C80 with their longer lived 
pigmented inks. That seems to me to be a reasonable solution / 
workaround until someone comes up with a montotone inkset that is 
less problematic in terms of longevity and printer plugging.
