A watermark is a mark, visible like a logo overlay or invisible like an embedded signature, that asserts ownership of an asset or controls its use. It is not the same as rights metadata: the watermark sits on the asset itself, while rights metadata records the terms in the record.
Why it matters
Watermarks protect assets when they leave the safe walls of the DAM, in previews, proofs, or shared portals. They deter misuse and make provenance visible without relying on the viewer to read metadata.
How it shows up in practice
A stock library serves watermarked previews and removes the mark only on licensed download. A brand shares unwatermarked finals internally but watermarks comps sent to external reviewers. Some DAMs apply watermarks automatically to certain renditions based on rights status.
Common mistakes
- Relying on watermarks alone instead of also enforcing permissions and rights.
- Watermarking final approved assets that should ship clean.
- Applying marks so heavy they ruin the preview, or so faint they do nothing.
