How to Use the Stamp Tool in Adobe Acrobat CS6
You can use stamps to identify documents or to highlight a certain part of a document in Adobe Acrobat CS6. Common stamps include Confidential, Draft, Sign Here, and Approved.
The stamps are grouped into sections, and you can access them from the Annotations section of the Comment panel. Some stamps automatically add your default username along with the date and time you applied them to the document; these stamps are available under the Dynamic category in the Stamps menu.
The more traditional business stamps, such as Confidential, appear under the Standard Business category. You can access each of the categories by clicking the arrow to the right of the Stamp tool in the Comment & Markup toolbar.
To apply a stamp to your document, follow these steps:
Select the Stamp tool by selecting Comment→Annotations then clicking the Stamp tool.
Click the arrow to the right of the Stamp tool and from the menu, choose either the Dynamic or Standard Business stamp.
The first time you use the stamps, you may be asked to input your information so Acrobat can include your identity as the user applying the stamps. If you click the Don’t Show Again option when asked to enter your identity, you won’t need to do this again.
Click within your document at the location where you want the stamp to appear.
