The Complete QA Checklist
Source factory quality without a quality verification system is gambling. This checklist provides the structured evaluation framework used by professional packaging buyers to qualify and monitor suppliers.
Pre-Production Quality Gates
Material certification verification confirming board grade, thickness, and composition before production begins with color proof approval against Pantone or brand standards. Pre-production sample sign-off as the binding quality reference for the entire order.
In-Production Quality Checks
Inline printing inspection at startup and at regular intervals throughout the run with die-cutting precision verification checking dimensional accuracy against specifications. Assembly quality monitoring of glue application, folding accuracy, and magnet placement.
Pre-Shipment Final Inspection
AQL 2.5 sampling with critical defects requiring zero tolerance, major defects at maximum 2.5%, and minor defects at maximum 4.0%. Inspection report documentation with photographic evidence.
Material Testing Requirements
Board thickness and GSM verification using calibrated measurement instruments with rub and scratch testing for coated surfaces. Adhesion testing for glued joints and foil stamping. Color measurement with spectrophotometer Delta E <3 target.
Communication Standards
Written specifications are the single most important quality document. Every requirement should be measurable and verifiable. Quality disputes are resolved against the approved pre-production sample and written specifications, not verbal agreements.
