Hi Mike,
in the office where I work, we still have the old FM 10 installed.
I checked this here and it is still the same as with the other FM
versions. (BTW, I always work with "save as PDF", stopped using the
print to ps-file nonsense in 2007 with FM 8.)
Well, how do you know that there is an overprint?
This will be decided while effectively printing or separating, it cannot
be seen as such in the PDF. (Not in my test...)
Here is the result, checked with the "Quite revealing" tool.
The black color was successfully set to "overprint" in FM 8, FM 10 and
FM 2017:
The rectangle behind is defined as knockout (both screenshots show the
same area of the PDF).

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!
:)

Hi Mike,
I checked using a simple rectangle and some text.
I checked the behaviour with FM 8 and FM 2017 (no FM10 installed)
Changing the color definition to "overprint" worked, as the pdf has
marked the black color as "overprint".
Here the info in the Acrobat "output preview" tool for the modified
file:
In case the normal color definition is used, "Page has Overprint" will
show a "No" in the resulting PDF.
I cannot say more about this.
Of course, for overprint or knock-out to become visible or effective,
a separation is necessary.
