Discoloration after pressing can occasionally occur in heat transfer processes (DTF, vinyl, toner transfers, etc.) and is typically related to application conditions rather than any single product.
The most common factors include:
• Heat & pressing conditions
Excessive heat, uneven pressure, or direct platen contact without a protective sheet can lead to scorching or dye shifting - including during a second press.
• Garment type & fabric sensitivity
Certain materials, such as polyester, garment-dyed fabrics, or lower-quality blanks, can be more sensitive to heat and may experience dye migration or temporary darkening.
• Transfer quality & curing
If a transfer is not fully cured or properly bonded (due to lower-quality inks, powders, or insufficient press time/temperature), it may react inconsistently during post-pressing.
• Ink and material compatibility
Non-standard or lower-grade consumables (including certain dye-based inks) may behave unpredictably when exposed to additional heat cycles.
In short:
If the original transfer is not properly applied (such as using lower-quality inks or powders, or incorrect curing time and temperature) it may be more prone to discoloration or reduced durability.
✅ Best Practices for Consistent Results
- Use a protective sheet (Teflon is recommended) to protect your image from direct heat press, during final pressing
- Use high quality consumables (inks, powders, vinyls etc) and recommended press settings for both transfer and garment
- Test new garment types or materials before full production
