Quality Control
When you source labels from another continent, the cost of a defect is not the label — it is the filling line that stops, or the shipment held at customs. Our quality system is built around catching problems before they leave the factory.
Three Control Points
| Stage | What we check | What you get |
|---|---|---|
| Before printing | Artwork preflight, colour management, sample confirmation | A signed-off standard sample before production starts |
| During printing | Inline vision systems, scheduled inspector checks, batch coding | Full traceability from raw material to finished roll |
| After printing | 100% roll inspection on seven high-speed machines | Defective labels removed before packing |
Before Printing — Sample Confirmation
Our prepress team checks your file before anything goes on press: resolution, bleed, trapping, colour space, minimum line weight and barcode readability. If something will not reproduce well, you hear about it at this stage rather than after a run.
You then confirm a sample. Screen proofs are useful for layout but unreliable for colour — monitor calibration and ambient light both affect what you see. For jobs with specific brand colours we produce a physical sample on the actual face stock, either from the digital line or a short press run.
Once you approve it, that sample becomes the production standard. Our colour management system holds the same appearance across presses and across repeat orders, so batch three matches batch one.
During Printing — Traceability
Two inline vision systems on the flexo presses compare what is printing against the approved file in real time. Quality inspectors check every order at fixed intervals through the run rather than only at the end.
Every batch we produce carries a control code, printed on the outer packaging. That code traces back through the whole chain: which material lot was used, which artwork version, which sample was approved, which press and which shift ran it.
Why this matters: if a problem surfaces on your line six weeks after shipment, we can identify exactly where it originated instead of guessing — and fix the cause, not just replace the labels.
After Printing — 100% Roll Inspection
Seven SMART-330 and SMART-370B high-speed inspection machines against four printing lines is deliberate over-capacity. Every finished roll passes through one. Defects are flagged and removed, not sampled.
Sheet products go through a dedicated sheet inspection unit installed in 2025.
Packing for a Long Journey
A label that passes inspection can still arrive unusable. Sea freight to West Africa or South America means weeks in a container with swinging temperature and humidity.
- Rolls are sealed in plastic film against moisture before boxing
- Cartons are packed to prevent core crushing and edge damage in transit
- Batch codes are printed on the outside so you can identify contents without opening
Testing Beyond Visual Inspection
Inspection catches printing faults. It does not tell you whether a label will still be readable after six months on a chemical drum, or whether it will peel off a bottle in an ice bucket. That is what the laboratory is for.
- Friction resistance — will print survive handling and transit
- Holding tack — will the adhesive stay put under load
- RoHS — heavy metal content for export compliance
- High temperature — sterilisation, engine bays, hot fill
- Low temperature — freezer and cold chain
Certification
ISO 9001 quality management. SGS and BV certified. National High-Tech Enterprise. Some products carry UL certification. Certificates are available on request for supplier qualification files.
