Transparency - background as well as layers of filled objects the same color as the background.

Hey there, I am trying to figure out how to create a single color line art from a document created that has while and black filled objects that creates a design that appears to have dimension. My question is how do I make all the while areas which would include the white background transparent as to leave the only one color (black) in front of a transparent background. This is for the purpose of a second party printing a film positive for burning a screen.
