Quality control
Four elements of an auditable inspection plan
Approved reference
Seal, date and identify the approved sample with linked files and limits; keep reference ownership and storage controlled.
Version identity
Use unique file names, revision dates, SKU codes and approval status so obsolete artwork cannot return to production.
Storage condition
Set temperature, humidity, stacking, sunlight, odour and shelf-time limits for materials and finished packaging.
Change control
Record what changed, why, who approved it, affected SKUs and whether price, sample or delivery must be reconfirmed.
Execution method
Four actions from RFQ to production
Translate expectations into criteria
Use dimensions, tolerances, test methods and defect photographs.
Inspect at the right stages
Place controls at incoming material, first article, in-process and final release as risk requires.
Record traceable results
Identify lot, SKU, sample size, inspector, tools, findings and disposition.
Close corrective actions
Contain affected stock, verify root cause and confirm the fix before repeat release.
FAQ
Questions buyers often ask
How should an approved packaging sample be controlled?
Identify and seal the approved sample, record what it proves and does not prove, link its files, and control custody, condition and replacement.
What should be written in the specification?
At minimum, define Approved reference, Version identity, Storage condition, Change control, then link quantity, sample, timing, inspection and the approved revision.
Is a physical sample needed?
A decision involving structure, material, colour, finish, assembly or use performance normally needs a physical sample matched to that question; a screen proof cannot approve everything.
Can the previous standard be reused for a repeat order?
Reuse a controlled standard only when files, material, structure, supply chain and use conditions remain unchanged. Record every change and decide whether resampling or reapproval is required.
