Digital BW, The Print

Okay, I'm tying to do it, but it doesn't seem to be working. I'm in Color
Settings, I use the Grayscale Working Space dropdown menu and choose Custom
Dot Gain. But as I adjust the curve, I see my little layer masks icons
change, but not the image itself. The other time I tried it I saw the color
swatches of my swatch pallet change, but not the image. What could I be
doing wrong?
