Adobe CS: Acrobat 8 Preflighting and Fixups
Preflighting PDFs in Acrobat Professionals keeps getting better with each version. In previous versions of Acrobat you could run PDFs against the Preflight tool and it would either pass or fail. If it failed you would then have to manually resolve the problems in the PDF or by generating a new PDF. In Acrobat 8 Professional you can now apply "Fix-ups" to correct the most common problems encountered in working with PDFs for print.
