Actually, I would never recommend ZIP for "monochrome" images. CITT Group 4
should work just fine. We know of no problems associated with that compression
either in distillation and/or display in Acrobat or Reader. I suspect that
there is another variable that you haven't tracked down yet.

I have only the vaguest notion what the difference is between them, and no notion of why one setting  seemed to work with Word files but not with Frame 7 files, but the release is out and I have time to research it later.
