About backgrounds and watermarks
Backgrounds are primarily used in a Web browser to create a more interesting background for online viewing. However, you can display backgrounds in Web layout and most other views, except normal view and outline view.
Watermarks are text or pictures that appear behind document text. They often add interest or identify the document status, such as marking a document as a "Draft." Watermarks are intended for printed documents.
Use gradients, patterns, pictures, solid colors, or textures for backgrounds. Gradients, patterns, pictures, and textures are tiled, or repeated, to fill the page. When you save a document as a Web page, the textures and gradients are saved as JPEG files and the patterns are saved as GIF files.
You can see watermarks in print layout view or on a printed document. If you use a picture, you can lighten it, or wash it out, so that it doesn't interfere with document text. If you use text, you can select from built-in phrases, or enter your own.
