This is a question that I get from time to time: Can FFC add a document page as a watermark?
Although there's no fecility to explicitly enable this, a workflow to add document pages as watermarks is relatively simple to build.
The following workflow will add the first page of the document s a watermark on page 1
The key is to split off the page (or pages) that you want to add as watermarks and save them at a known location with a unique name.
In this case, Split copies page 1 to one workflow branch and sends the rest of the document to anther branch.
Page 1 is then saved with a known and unique name using the FFC Job ID variable
The two files are then joined. This is done to ensure the files are saved before the watermark node that will place the page in the document.
Since files are always joined in the order in which they are split, the first page of the joined document will contain the page that was saved for use as a watermark.
The delete component then removes this page which leaves only the original document.
The last step is to add an image watermark that points to the saved PDF
