Quality Control Checklist
- 1.Color accuracy — Delta-E measurement per Pantone/RAL reference
- 2.Print quality — registration accuracy, dot gain, ink density
- 3.Material specification — paper grammage, cardboard thickness, plastic micron
- 4.Adhesion and assembly quality — open/close durability, magnet strength
- 5.Cutting and folding precision — die-cut accuracy, crease quality
- 6.Foil print adhesion strength — tape test verification
- 7.Bar code / QR code readability
- 8.Migration testing for food packaging (food safety compliance)
⚠️ Common Pitfalls
- •Color variation — color shift between print start and end. OK sheet sign-off is essential
- •Paper/cardboard grammage fraud — ordered 350gsm but produced 300gsm. Grammage check per batch
- •Insufficient adhesion — opening of rigid boxes, magnet detachment
- •Bar code not reading — size tolerance or insufficient contrast
- •Non-food-safe ink and adhesive usage in food packaging — migration risk
💡 Pro Tips
- •Get 'OK sheet' (approved print sample) for every print job — this is the reference standard
- •For luxury packaging, don't proceed to mass production without sample approval — ensure material and workmanship match
- •For foil printing, optimize temperature, pressure and dwell time parameters with the operator
- •For food packaging, specify low-migration ink and adhesive in the contract
- •100% scan all bar codes in the batch — even one unreadable box makes retail sale impossible
