Add a Watermark to a Slide
You can’t create a simple textual watermark on a slide as you can in a document, but you can achieve a similar result by inserting WordArt and making it nearly transparent so that the slide content is visible through the WordArt text. Similarly, you can insert a shape, add text to it, and then adjust the transparency of the shape and the text to mimic a textual watermark. You can also format an image, such as a clip art image or a photo, as a watermark. The key difference between these methods and actual watermarks is that these methods place the nearly transparent watermark content in front of the slide content, rather than behind it, so the fake watermark could obscure the slide content.
