04 / Acceptance and handover
Prove the result under a representative production condition
Use qualified ink and surface evidence and verify print, cure, rub, product-contact boundary and storage. Retain measured evidence for container material and surface treatment and adhesion, migration and durability proof with method, conditioning, limit, deviation, witness, approval and review trigger. Run approved material lots and artwork at representative surface and speed conditions, challenge wrong and unreadable identity, verify position, adhesion, shrink, scuff and code quality, test reject security and reconcile materials and serialized or lot data where applicable. Put the sample or test material, method, instrument, production state, duration, limit, witnesses, retained record and deviation authority in the protocol before testing begins. Requalify when a product, package, site, speed or connected system invalidates the accepted basis.
