Hot stamping uses a heated die, pressure and metallic foil to transfer a logo onto leather. The best setting depends on the leather finish, foil chemistry and artwork size, so a short test is more reliable than one universal number.
1. Choose foil made for leather
Use foil specified for leather, PU or synthetic leather. Smooth coated surfaces usually transfer more easily than oily, textured or heavily finished leather. Choose a roll slightly wider than the complete logo to ensure full coverage.
Test the actual production material. Two leathers that look similar may use different coatings and require different foil or settings.
2. Start with moderate temperature
For WTONG metallic foil, begin within 80–120°C. Start near the lower end, make one impression, then increase the temperature gradually. If the foil does not release completely, add a little heat or dwell time. If edges spread or the leather surface becomes glossy, reduce the heat.
3. Increase pressure gradually
The die must contact the surface evenly. Begin with light-to-medium pressure and increase only until every part of the logo transfers. Too little pressure causes missing areas; too much can crush the leather grain or create a deep outline around the design.
4. Use a simple test sequence
✓ Secure the copper die and preheat the machine.
✓ Place the foil with the metallic side facing the leather.
✓ Make a short test press on scrap material.
✓ Change only one variable at a time.
✓ Record temperature, pressure and dwell time after a clean result.
For small logos and short production runs, a manual press such as the WT-90DS gives the operator direct pressure control. Pair it with a correctly sized copper die and a stable positioning fixture for repeatable placement.
QUICK TROUBLESHOOTING
If the result is not clean
Why is the foil patchy?
Check that the surface is smooth, the die is level and pressure reaches the complete artwork. Then increase temperature or dwell time slightly.
Why are the edges blurred?
The temperature, pressure or dwell time may be too high. Reduce one variable and test again.
