Tips
- Automatic text: put
{filename},{page},{pages}or{date}in the text. For example,CONFIDENTIAL – {filename} – page {page} of {pages}. - Tiled repeats the watermark across the whole page, which makes it hard to crop out.
- Text watermarks support English and Western European letters (é, ü, ñ and so on).
- The watermark is added on top of the page. A low opacity keeps the page easy to read.
