Export as flat PDF?

I have DRAW but also have Designer X6. Is it possible to publish to PDF as a completely flattened document? I'm trying to create a multipage file where all the text and line art are flattened like a JPEG. I've tried several different settings in the "Publish to PDF" menu and no matter what I am able to reimport the layers and objects as objects. I want this flat so nobody can rerended and steal my artwork, if that makes sense. If it were just one document I'd just export each sheet as a JPG and use that BUT I have 20 pages. Any suggestions would appreciated!! Thanks
