Digital BW, The Print

I think you are probably right that the Epson driver prints black text with
black ink only. Paul's test should probably be to scale the density/opacity
of the type to 75% gray. Then send one to the Piezo and the other put
through his RGB/curves workflow. Hmm but even at that, one tone of ink is
still not a good test of across-the-board quality.

What if he superimposed white text over a step wedge? In that scenario the
edge of the type would be defined by the response of the system at each tone
along the way.
