Adding Backgrounds to PDFs
Backgrounds are content that appear behind the text/images of a given page. You can use either a solid color or a custom image as a background, and you can apply backgrounds to either a single page or a custom page range as desired. Click the Organize tab, then click Background and click Add to add a background to the current document:

•The Source options determine the source of the background:
•Select From Color to add a color-based background, then select a color from the dropdown menu.
•Select Name to specify a file to be used as the background, or click the icon to select a file from the local computer. If you are using a document that contains multiple pages, then use the Page number box to specify the page number of the page/image to be used.
