Why would a PDF add a tiled text watermark?
Toenhance copyright protection
when PDF files are original content, such as some design drafts and internal files, and are worried about being copied or used by others with screenshots, tiled text watermarks are added uniformly to cover the entire page of content. Compared with watermarking only in corners, tiled watermarks are more conspicuous and more difficult to be cut and removed separately.
Prevent malicious modifications
some PDF files may be used in contracts and important information. If they are modified by others, they will cause trouble. Adding a tiled text watermark can remind the receiver of the nature of the file and reduce the risk of malicious modification to a certain extent. Even if someone takes a screenshot or partially intercepts it, the watermark will still remain in the screen.
Differentiate between file uses
in actual work, there are often drafts, samples or tests and other different uses of PDF files, if not marked, it is easy to be mistaken for the official version, by adding a tiled text watermark, you can make each page clearly display the purpose of the file, to avoid confusion.
