Open any version of Adobe Acrobat, which allows the creation of watermarks whether or not a specific document is already
open. To add a watermark to a specific document, click "File" and choose "Open." Select your document.
Click the "Document" menu at the top of the screen and choose "Watermark." Click "Add." A new dialog box should appear.
Type the text you want to use for your watermark into the "Text" box, or click "Browse" under the image section and choose
a saved image from your computer to use.
Click and choose settings from the menu boxes, such as text rotation angle, image size or position on the page. Choose
whether you want the watermark to appear in front of the text on your documents or behind it. Lower the "Opacity" option to
create a more transparent watermark.
Click "OK" when you're finished editing the watermark. Return to the watermark menu at any time to adjust the settings.
