Using the PDF Stamp tool

You can use the Stamp tool to imprint the document with a predefined graphic mark that mimics real-world rubber ink stamps used to indicate the status of the document, such as Draft, As Is, Confidential, or Final. When you use one of these marks, you can also add a hidden comment to it, just like you do when creating a comment with the Note tool. Acrobat comes with a wide variety of ready-made stamps that you can use (which are organized into different categories). You can also add your own marks to these collections. Don’t confuse adding a stamp to the PDF document you’re reviewing with digitally signing a PDF document.
When you stamp a document, you’re simply adding another, more graphic form of notation to the document. When you digitally sign a document, however, you’re actually using a secure method for identifying yourself as the signatory. Use stamps when you want to call attention to the current state of the PDF document or add a very visible review comment, such as red-flagging a change with, of all things, a red flag. Digitally sign the PDF document when you’re ready to freeze it and prevent all further changes to it.
To add a stamp to a PDF document, take these steps:

1. Click the Stamp tool on the Commenting toolbar.
2. Click the Stamp tool mouse pointer at the place on the page in the PDF document where you want the stamp’s imprint to appear. When you click the Stamp tool mouse pointer, Acrobat inserts the lastused stamp at the place you click (this is the Approved mark when you first begin using this feature in Acrobat).
3. If you want to use a different stamp, click the mark that you just added to the document to select it (you can tell it’s selected because a bounding box with sizing handles at the corners appears), and then click the Stamp tool pop-up menu to select another stamp.

The Stamp tool pop-up menu and submenus contain all the built-in stamps available in Acrobat 6. These are divided into three categories: Dynamic, Sign Here, and Standard Business. Dynamic stamps like the Approved stamp, automatically display author, time, and date information, as opposed to Standard Business like the For Public Release stamp shown selected on Stamp tool pop-up menu in the figure, which has no additional dynamic information. The Sign Here category provides a number of stamps used to highlight digital signature areas, much like the Sign Here Post-It notes you may have seen attached to paper documents from your accountant or lawyer.
