Watermarks at 15-30% opacity protect ownership without making the underlying text hard to read.
A diagonal watermark crosses all four margins, making it far more difficult to remove with a simple crop.
Digital watermarks discourage misuse but do not technically block copy-paste; combine with encryption for stronger protection.
Stamp each copy with the recipient's name or email — this creates a clear paper trail if a file leaks.
Text watermarks scale cleanly at any zoom level; image watermarks allow logos but may lose sharpness at some sizes.
Apply the watermark to one page export to verify opacity, position and font before processing the full document.
Apply watermarks only to appendices or specific sections without re-processing the entire document.
Using your brand typeface and primary colour makes the watermark feel intentional rather than a generic afterthought.
