The role of watermarks

Watermarks play a vital role in PDF documents, it is not only a simple visual identity but also a combination of functionality and security.👀

✅ Copyright protection and traceability

  • Prevents unauthorized dissemination: Add text watermarks such as “strictly prohibited reproduction” and “internal use” to clarify the attribution of documents and deter misappropriation.
  • Tracing the source of the leak: Add unique identifiers (e.g. “user ID + email”) for different recipients, so that the responsible person can be precisely located in case of file leakage.

✅ Document status management

  • Identifies a file attribute: Process control: indicate progress with “draft”, “under review” and “finalized” to avoid misuse of old versions.
  • Classification alerts: Reminds contacts of information security through “confidential” and “top secret” watermarks.
  • Warning role: Watermarks such as “Invalid Copy” and “Expired Document” directly indicate the risk of document failure.

✅ Brand strengthening and promotion

  • Visual penetration: Flat company logos or web addresses as background watermarks, subconsciously conveying the brand message every time you read it.
  • Professional image building: Add sophisticated Logo watermarks to external documents (e.g. quotations, reports) to enhance credibility.

✅ Security protection (anti-disclosure)

  • Sensitive information masking: When sharing files, cover key data areas (such as ID numbers) with a translucent watermark for both readability and security.
  • Anti-screenshot forensics: Tiled watermarks (e.g., diagonal “samples”) interfere with the secondary use of screenshots and make information extraction more difficult.
