Digital BW, The Print

You may not be doing very much wrong at all. Printing with black ink
only is not a very good way to get grey tones - you are essentially
halftoning _everything_ so there's going to be a point where there are
so few black dots in your grey area that it looks pretty much white.

Quadtone prints were basically invented in order to fix this problem -
so you can have real grey tones instead of halftones. Don't count on
black ink only giving you great prints - maybe "Good enough" maybe
"Fine" and maybe "I like it" but they aren't going to look as good as
your quadtones. (IMHO of course)
