Digital BW, The Print

What does the monitor gamma have to do with the fininshed print if 
the monitor matches the printed image? I use Windows XP and have had 
my monitor set to Gamma 2.2 for all usage of Photoshop and all other 
programs. Today I reset my monitor Gamma to 1.8 and get a much longer 
tonal range in my images. The Gamma 2.2 compresses the lower values 
too much for any detail in the 90 to 95 per cent range to be visible 
in the print. I use MIS FSN inks and an adjusted printing curve from 
their website as well to print to an Epson 1280 on Epson Matte 
Heavyweight paper. I also use the plugin from PiezoBW and select 
their inkset and Epson Matte Heavyweight paper profile. A change to 
the Dot Density % from 100 to 125, which lays down more ink creates a 
match between the print and the monitor, with the print being the 
criteria to match.
