Keep the control, face contact and edge contact as different samples
This is a worked planning example, not a completed test, customer record, legal approval or universal acceptance standard. Replace every demonstration reference with your own project input. Keep unknown items on hold with a named owner.
| sample | example contact scope | required reference | observation | approval limit |
|---|---|---|---|---|
| Clean control | No deliberate oil contact | Same applied construction and bottle | Starting edge and print condition | Not an oil-resistance result |
| Face-contact sample | Named incidental surface contact | Actual substance and agreed sequence | Face appearance; print transfer; later marking | Only the agreed face contact |
| Edge-contact sample | Named credible contact at exposed edge | Application location and observation period | Staining; movement; edge condition | Does not imply immersion resistance |
| Later-print field | Actual proposed ink or ribbon combination | Printer and marking settings | Field remains readable under the agreed review | Not covered by surrounding laminate alone |
Use the record
Identify your container, artwork and proposed specification. Keep evidence references beside decisions. The responsible buyer and supplier should agree the conditions and approval scope; example rows are instructions, not pass results. Retain revisions when an input changes.
