[Framers] Overprint Not Working in FrameMaker 10 and Acrobat Pro 2017

[Mike Wickham]

Ok, this has gotten way weirder, but I have managed a partial solution 
that lets me create this particular file the way I want. I suspect the 
book will bomb out, though. I've always had trouble getting Save as PDF 
to work with books. Here is what fixed it enough for now:

1. I used Save as PDF. Print to PDF does not seem capable of passing 
overprints to PDF. But, even using Save as PDF, Acrobat may say "Page 
has Overprint: Yes," but still knockout backgrounds.

2. Changing ink from 100% black to 99% black in my Overprint Black color 
definition, makes it overprint. Oddly, creating an Overprint Yellow at 
100% works fine. Magenta and Cyan do not overprint, even at 99% ink. 
Fortunately, I only need black to work in this book.

Anyway, I've been troubleshooting for two days. As long as black works, 
I'm probably okay. I'll be back if I can't get the whole book to Save as 
PDF.

And, a final note to Heiko, I'm curious how you created your PDF and if 
you actually turned off individual ink plates to see if overprints 
actually worked or if Acrobat was just lying to you, like it did to me! :)
