Selection framework
| Decision | Starting point |
|---|---|
| Facestock | Polyester, polypropylene or qualified specialty film |
| Thermal transfer with matched durable ribbon | |
| Adhesive | Qualified for substrate and temperature |
| Exposure | List exact chemicals, concentration and contact time |
| Outdoor life | Test UV, water, abrasion and temperature cycling |
Validation checklist
- Request supplier resistance data
- Test each chemical separately
- Include cleaning and rubbing in validation
- Reverify barcode quality after aging
Final recommendation
Request samples and test the exact printer, settings, ribbon, facestock and adhesive on the production surface. Verify barcode quality after the complete environmental cycle, not only immediately after printing.
