Hello and thank you for leaving this question.
Expert PDF allows you to add watermarks to your PDF document. Watermarking is available only when the Insert Module is activated. To do this, click Watermark on the Watermark group, then select Add Watermark from the drop-down menu. Once selected, the Add Watermark dialog appears as the attached file. Choose a source you want to insert a watermark from: Text. Enter text into a text field. File. Click the Browse button to choose a file. If you choose to create text watermark, you can set the font face, font size, set it to Bold or Italic, and add text colour. You can view the changes performed while creating a custom watermark on the Preview pane of the Add Watermark dialog. Once all the options are defined, click OK to make the watermark appear in the document.
