Bright shelf light exposes weak registration
Duty-free and specialty retail lighting is unforgiving. Cold foil and metallic inks that look perfect under desk lamps can show streaks, chatter, or misregistration under narrow-beam spots.
Prepress compensation
Tube distortion maps differ by oval versus round and by shrink after sealing. Build compensation into step proofs on real tubes, not only flat mockups.
Acceptance standards
Define tolerances for foil skew, pinholing, and rub resistance after flex. Attach photos of acceptable versus reject so QC aligns with brand.
Closing
Luxury metallic decoration is a manufacturing sport. Budget time for iteration; shortcutting prepress creates expensive trash.
