Digital BW, The Print

I print with an Epson 1280 Hextone inks and use Paul Roark curve for 
cool neutral. The way I calibrated the monitor and printer was to 
take a 21 step grayscale on the screen and with a curve layer match 
the percentages of the steps and printed that out. It matched just 
right after applying Paul Roark's curve. The dumb question is--Why 
do the percentages change so much on the image on screen and yet 
match so well in the finished print of it. I know the screen image 
is false colors, and that may be the answer to my question. I would 
welcome any and all input in order to understand better the 
connection between the false screen image and the printed image. I'm 
satisfied with what I do, I just would like to know why.
