Spine calculation related to Express vs. Premium Paper

Posted:07 Aug 2011 (17:54 UTC)
I'm uploading a pdf from iPhoto for a hard cover image wrap(8.5x11). How is my book affected by my decision to use Express paper vs premium. Since the latter produces a thicker book, I image this would adjust the printing on the spine and it would be off center. Please advise. Also, which printing method is closest to the Apple hard cover book produced by iPhoto. Thanks!
