First, I apologize if this isn't the correct subforum for this question, but all the others seemed to be game-specific.

I'm someone who's interested in potentially funding a commercial print run in the future, and it would be helpful to know who companies like Onyx Path, or the White Wolf of yore, go to for their print runs.

But it's starting to feel like these companies go out of their way to keep this information hidden, because I can't seem to find it anywhere. You'll get a "Printed in Canada" in the book, but that's about it. I'm sort of confused about why...
