Digital BW, The Print

To print using an QuadTone RIP ABW profile, set Photoshop's Color
Handling menu to Let Photoshop Determine Colors, select your ABW
profile from the Printer Profile menu, set the rendering intent to
Perceptual. Black Point Compensation won't matter. Might as well leave
it on. Then in the Epson driver, use the exact same settings as you
used to print out the profile target.

The same ABW profile can be used for soft-proofing as well as printing.
