Digital BW, The Print

Grady,
I don't refill cartridges.....I use a continuous flow system from 
CIS. They are dye based inks, but according to everything I've 
read, their quad blacks are archival 100+ years. The bottles of 
ink are marked to match the colors of the print head. I do no 
other printing adjustments other than lightness/darkness and 
contrast in Photoshop before I print. I have my monitor balanced 
to match the printer output, so what I see is what I get....perfect 
results everytime.
Hope this was helpful.
Don
