Coating Filling Records: Keep Reworked Packs Separate from First-Pass Output
A finished pack that passed after rework has a different process history from one accepted immediately. Preserve that distinction when analysing filling performance and investigating later packaging issues.
Updated · NANOLAB Knowledge
The key distinction
The final accepted quantity is useful for inventory, while first-pass output helps assess process stability and workload. Rework records should identify the approved action and the final acceptance check without treating the unit as a new unrelated pack.
Practical checks
- Define first-pass acceptance and authorized rework.
- Link reworked units to their original run.
- Report final yield and first-pass results separately.
Example
Illustrative example: a run produces 500 accepted packs, including 25 that required an approved label correction. Reporting 500 first-pass packs would hide the extra work and its cause.
Scope and limits
Do not invent a rework method or return questionable packs to saleable stock without the required release. Use the approved product and packaging process.

Coating Filling Runs: Inspect the First Units After a Stoppage
Restart conditions can differ from steady production because material and equipment have remained idle. The first accepted units should confirm that the process is still controlled.
Coating Production Yield: Distinguish First-Pass Yield from Final Yield
First-pass yield measures units accepted without rework. Final yield also includes units accepted after an approved correction. Reporting only final yield can hide process instability.
Coating Printer Files: Keep Editable Artwork and Production Output Linked
The editable design file and the production-ready output should remain linked by revision. Otherwise, a later correction can be made to an old source file and reintroduce content that was already removed from the approved print version.
