I'm creating packaging dielines, and the white areas on my dielines show up as black in the AI preview and in the Mac preview (the colors appear normal in Adobe Acrobat). The printer is printing the wrong version with the black in place of white, and I don't know how to fix the file for the printer. When Illustrator is open or when the file is open in Acrobat, the file is fine and the colors are fine. It's only in the Mac Preview that the colors come out wrong, and the printer is somehow printing this version.
I spent time trying to fix same issue, answering this just in case someone else stumbles on this post not knowing how to fix it. When it happened to me, I noticed after a while that it happened after I had outlined the text in the document. I resolved the issue by outlining individual parts at a time.
