While Acrobat provides some basic editing capabilities, if you need to regularly open and perform extensive edits to multiple objects within numerous PDF documents, then you should consider acquiring a third-party extension designed specifically for this purpose.
There are numerous editing plug-ins for Acrobat, but the one with which I am most familiar and have had much success is PitStop from Enfocus. PitStop provides a wide and deep range of global, page-based, and individual-object editing tools, including a complete preflighting and correction tool set, automation functions, a certification tool for prepress and PDF/X standards, and even a server-based versions of its tools. If you need to edit a lot of PDFs, get PitStop. I ve included a trial copy of this software on the book s companion CD.
