Custom Packaging Quality Control Process

Stage 1 — Prepress Artwork Check

• Verify artwork resolution (min 300 dpi), bleed (3 mm), CMYK conversion, embedded fonts
• Pantone color spec review and closest CMYK build for reference
• Foil / spot UV / embossing / debossing zone alignment on the dieline
• Barcode / GS1 DataMatrix / QR code readability test
• Digital PDF proof sent to buyer for artwork sign-off

Stage 2 — Color Proofing

• Digital color proof (Epson calibrated)
• Wet proof for offset jobs above 5,000 PCS on request
• Pantone color matching on target material and coating
• Foil sample swatch (gold, silver, rose gold, holographic) confirmation

Stage 3 — Material Inspection

• Board thickness measurement (calliper)
• Paper weight verification (gsm)
• Food-grade / FDA / EU 1935/2004 material certificate check for food and pharma packaging
• Magnet strength / neodymium grade verification for magnetic boxes
• Pouch film lamination bond strength and seal integrity test

Stage 4 — In-Process Inspection

• First-article inspection at each print run
• Color density inspection every 500 sheets
• Foil registration / embossing depth check
• Die-cut precision measurement
• Magnetic closure and structural assembly test

Stage 5 — Final AQL Inspection & Pre-Shipment Audit

• AQL 2.5 (major) / 4.0 (minor) sampling per ISO 2859-1
• Cosmetic defect check: color, print, foil, dent, scratch
• Structural defect check: assembly, closure, insert fit
• Functional test: magnetic closure hold, tamper-evident seal, pouch seal integrity
• Pre-shipment photo & video audit report sent to buyer before container loading
