I have an Adobe Acrobat PDF file on Macintosh OS X Lion that I need to overlay some plain text on top of at a particular position relative to the original PDF. Previously I have created a Microsoft Word document that contains the positioned text and printed the page twice, once for the original PDF and a second time for the Microsoft Word document to get the overlay. This is rather cumbersome and there is some slop sending the paper through the printer two times such that the text is not exactly aligned between the two print outs.
Instead I would like to create a new PDF (or perhaps some other format file) that combines the original PDF together with the positioned text I want to overlay such as in a Microsoft Word document. The overlay should be transparent and not obscure anything from the original PDF, just like the effect of my manual double printing on the same sheet of paper.
I have access to Adobe Acrobat Pro X as well as other Adobe tools such as illustrator and wonder if one of these tools or another Adobe tool provides the needed ability or must I go outside the Adobe family of tools to accomplish this?
