Counterfeit protection is not a label you buy; it is a match between a threat and a feature. A hologram that stops a photocopier does nothing against a distributor peeling labels off and re-applying them, and a serial number that satisfies an auditor does nothing against a copy shop. This guide sets out the three tiers of security feature, what each one actually stops, and a table for choosing by threat.
1. Why "anti-counterfeit" is a family, not a product
Every anti-counterfeit label answers a specific question. Buyers who skip that step usually end up paying for a feature aimed at a threat they do not have.
- Overt features — visible to anyone: holograms, guilloche patterns, colour-shift ink, void messages. Cheap to check, easy to imitate badly.
- Covert features — visible only under UV, at a specific angle, or under a magnifier. Slower to check, so they suit spot audits rather than every unit.
- Forensic features — taggants, micro-text, coded fibres. Verified only with equipment, and used mainly to prove a case after a seizure.
The question to settle first is not "which feature is strongest" but "who checks, how often, and with what".
2. What each tier costs you in workflow
A feature only works if the checking step actually happens. Three practical limits decide that.
- Time per check. A UV lamp adds seconds per unit; a serial lookup adds a network round trip. Both are fine at a customs inspection and hopeless on a fast packing line.
- Who can check. Consumers, retail staff, distributors and investigators carry very different tools.
- What counts as evidence. A visible feature deters; a coded feature can be recorded and traced back to a batch.
Pick the tier by the check that will realistically be performed, then choose the feature inside that tier.
3. Choosing by threat
Work from the threat you are actually losing money to.
| Threat | Feature that answers it | How it is verified | Equipment | Goods value band |
|---|---|---|---|---|
| Whole-label copying | hologram, colour-shift ink, guilloche | eye, at arm's length | none | any |
| Peel and re-apply | frangible or void-revealing facestock | inspect the seal on receipt | none | mid to high |
| Transfer to another product | serial or QR tied to a batch record | lookup against the record | phone or scanner | mid to high |
| Internal diversion | unique per-unit code issued in controlled batches | reconciliation at intake | scanner plus database | high |
Two rows often apply at once. A tamper-evident seal over a coded closure is a common pairing, and the two features are chosen independently. Where the seal is the whole defence, start from frangible paper labels; where the label also has to warn or instruct, safety warning labels carry a similar construction with regulated wording.
4. What security printing cannot do
- It does not stop a determined copy of an overt feature. A hologram photographed and reprinted will pass a casual glance. Overt features deter opportunists, not organised copying.
- It does not survive a bad application. A tamper-evident label on a dusty or oily surface lifts cleanly, and the evidence with it. Surface preparation is part of the security.
- It does not replace a serial record. A code nobody looks up is decoration. The lookup step, and who owns it, has to be agreed before the labels are printed.
- It is not a regulatory claim. Requirements for specific goods are set by the destination market, and the label has to fit the scheme rather than the other way round.
FAQ
Which security feature is strongest?
None in isolation. Strength comes from layering a visible feature, a tamper-evident seal and a traceable code, so that defeating one still leaves the others.
Do I need equipment to check a security label?
Only for the covert and forensic tiers. Overt features and tamper-evident seals are checked by eye, which is why they are the usual first layer.
Can a QR code alone stop counterfeiting?
No. A code only helps if it is unique per unit, issued in controlled batches, and actually looked up. Printed in bulk with no record behind it, it is a design element.
Where should the feature sit on the pack?
Across a closure, seam or lid edge — anywhere that opening the pack destroys the label. A seal on a flat panel can be lifted and replaced without leaving a mark.

Start from the wider functional labels group covering waterproof, cold-resistant, flame-retardant and anti-static options. Tamper-evident work often pairs with the eco labels overview when the pack itself is paper-based. Send the threat you are seeing, who checks the label and with what, and a construction can be matched before samples are issued.
