Word comes with several common watermarks, including Draft, so you can let others know the status of your document. When you add a watermark, it'll appear on every page except a designated title page.
Click Design > Watermark.
In the Insert Watermark box, select Text and then click Draft.
Customize your watermark by changing the font, layout, size, colors, and orientation in the Insert Watermark box.
Tip: If you don’t see the watermark, click View > Print Layout. This view also shows what the printed watermark will look like.
