I'm having trouble saving my Word doc as a PDF (Mac Office 2011). The document itself has an edge-to-edge image as the background, only when I go to save it as a PDF, it "crops" about a .5" border on all sides making a white band on the edge of my document that should be all color.

As I'm not actually printing anything yet, I can't adjust the printer settings as many other forums have suggested. I've tried adjusting the document border settings to 0 on all edges, but I still get a border. What am I doing wrong?
