Heat Transfer Label for a Workwear Distributor in Portugal
A Workwear Distributor approached us with a heat transfer label requirement for the Portugal market. The brief was specific: a defined look, a hard launch date and a unit cost that had to survive freight and duty. This case study records what was specified, what went wrong in sampling and how the bulk order was delivered.
The challenge
- An interlining that bubbled after the first press
- Shrinkage that only showed up after the first wash
- A zipper puller that broke under pull test at the warehouse

What we specified
| Item | Heat Transfer Label |
|---|---|
| Client type | A Workwear Distributor |
| Market | Portugal |
| Order volume | 20,000 pieces across 4 specifications |
| Base material | Wood |
| Standard size | 8# Gauge |
| Finish | UV Printing |
| Sampling rounds | 3 |
| Delivery window | 8 weeks from PO to ex-factory |
| Compliance | RoHS |
How it was resolved
- We rebuilt the specification around Wood and locked the tolerance before bulk.
- The finish was moved to Matte Black Coating after strike-off tests showed better durability.
- A pre-production sample was approved and retained as the golden reference.
- Production ran with in-line inspection and a mid-run photo report.
- Cartons were packed to the client's own barcode and ratio specification.

Result
- 20,000 pieces delivered inside the 8-week window.
- Unit cost held within 1.5% of the original quotation.
- Inspection-related rejection stayed under 0.5%.
- The specification is now on file, so reorders reproduce the approved sample.
What we would repeat
Keep one accountable owner on both sides. Most delays come from hand-offs, not from machines.
