What is a Watermark?
A watermark is a translucent text or image superimposed on the main content of a document. Traditionally used on banknotes to prevent counterfeiting, it is nowadays essential in the digital age to mark the authorship of a PDF document.
Professional Use Cases for Watermarks
- Confidentiality notices: Write "CONFIDENTIAL" diagonally on internal documents.
- Copyright protection: Place your company logo or the word "Copyright" on infographics or E-books before distributing them.
- State management: Indicate that a document is a "DRAFT" or "APPROVED".
