Digital BW, The Print

Thank you Bernd.

I don't understand it either, but at least we know it's outside the driver.
I guess certain patterns have resonance at certain magnifications, and it
doesn't matter if that frequency is viewed on screen or in print.  (Forgive
what I'm sure is improperly used terminology.)
