You can edit PDF documents in Acrobat, but only in Acrobat X are tools improved. When you edit PDF documents there are several ways to do it. No margin printing in print files to pdf can edit using Adobe Acrobat, but Acrobat X editing tools are much better than before.
Design studios often have to edit PDF documents in order to alter a document created by someone else, or to make a last minute change without having to return to the source files. Please note that you can’t edit a PDF file with the free Adobe Reader – you need the full version of Adobe Acrobat to make changes. If you’re using Adobe Acrobat 9 or earlier, the changes you’ll be able to make will be extremely limited. The ‘Advanced Editing’ text tools are unwieldy to say the least.
