A watermark is an image or text that when printed appears in the background of a document. The watermark text or image is faded so that it does not distract from the content of the document but is legible. |
The property Document.Watermark returns a Watermark object.

WordApplication app = new WordApplication();

Watermark mark = doc.Watermark;

To use an image as a watermark, assign an image file to the Watermark object's Image property.

Watermark mark = doc.Watermark;
mark.Image = File.Open("somepic.gif", FileMode.Open);
