Digital BW, The Print

I'm using Lyson quad neutral inks on my 1280 with a continuous 
flow system with great results. There is no special software 
required....just convert your image to grey scale and then back to 
RGB and print as normal after adjusting contrast etc in 
Photoshop.....perfect results everytime. Needless to say, you 
have to have your monitor balanced to the printer output 
(lightness/darkness) to get an exact match.  I use the Knoll 
gamma software to accomplish this. I make a print and then 
balance my monitor to match the print, then save the settings to 
load when ever I print to a specific paper/ink combination. I don't 
bother with all these printer profiles, for I have found they don't 
really work for me. They are all based on the assumption that 
your monitor is calibrated the same as whoever made the 
profile....close, but no cigar! Makeing your own profile will give 
you the closest match so what you see is what you get.            
The ink archival life is 100+ years and I've had no problems with 
head clogs. I get excellent results with Ilford Gallerie classic 
pearl, Epson Colorlife/premium glossy and Hanemuel photo 
rag. Luminos quad blacks are made by Lyson and is the 
identical ink, but Lyson is cheaper, and you can buy in bulk.
