Add Watermark guide and tips
A diagonal watermark is hard to ignore and works well for DRAFT or SAMPLE. A horizontal watermark looks calmer and suits company names.
Light opacity keeps the page readable. Increase it if the watermark is hard to see on busy pages.
Watermark text supports Latin letters, numbers and common symbols.

Can the watermark be removed later?
The watermark is drawn onto the page, so it is not meant to be switched off. Keep your original file if you need a clean copy.
