It is the single source of truth for what a label should say and show. Other versions, such as language variants, pack sizes, market adaptations and print-ready files, are derived from it and verified against it. A master has a unique version identifier, a record of who approved it, and a controlled change process.

Why it matters for labeling

The key distinction is between comparing a new version against the master and comparing it against the previous version. A comparison with the previous draft shows what changed since last time, but not whether the complete document matches what was approved, so an error from several revisions ago can go unnoticed.

Common mistakes

  • No clear approved master, or several files that could be it
  • Approvals recorded against a file name rather than a specific version
  • Variants edited directly instead of being derived from the master
  • The final check done against the previous draft
