Cracking in DTF prints can be frustrating, but it’s often preventable. Here’s a detailed troubleshooting guide to help you fix and avoid cracking issues.
1. Low-Quality Film or Ink
🔹 Issue: Cheap or incompatible film and ink can cause weak adhesion, leading to cracks over time.
✅ Fix: Use high-quality DTF film and inks designed for durability. Look for brands with strong pigment concentration and flexible adhesion.
Tip: At The Print Minister, we offer top-tier DTF film and inks to ensure vibrant, long-lasting prints.
2. Incorrect Curing Temperature or Time
🔹 Issue: Under-curing leaves the adhesive weak, while over-curing makes it brittle and prone to cracking.
✅ Fix: Follow manufacturer guidelines—most DTF powders cure best at 160–170°C (320–338°F) for 60–90 seconds.
How to test:
✔ If the print feels rubbery or peels easily, it’s under-cured. Increase curing time slightly.
✔ If the print cracks when stretched, it’s over-cured. Reduce heat or time.
3. Poor Heat Press Application
🔹 Issue: Incorrect pressure, uneven heat, or low temperature during pressing can cause poor adhesion.
✅ Fix: Ensure your heat press settings are 160–170°C (320–338°F) for 15 seconds with medium-high pressure.
Checklist for a perfect press:
✔ Use a flat, even surface to apply uniform pressure.
✔ Preheat the garment for 5 seconds to remove moisture.
✔ After pressing, let the print cool before peeling the film.
4. Overstretching the Fabric
🔹 Issue: Some fabrics stretch more than others, causing prints to crack when the material is pulled.
✅ Fix: Use high-quality, stretchable DTF prints that move with the fabric. Avoid excessive stretching, especially on activewear.
Best fabric choices for DTF printing:
✔ Cotton, polyester blends, and fleece work well.
✔ Avoid overly textured fabrics that don’t bond well with DTF prints.
5. Washing & Care Mistakes
🔹 Issue: Hot water, bleach, or high dryer temperatures can weaken the adhesive and cause cracks.
✅ Fix: Follow these washing and care tips:
✔ Turn garments inside out to protect the print.
✔ Use cold or lukewarm water (hot water can fade prints).
✔ Mild detergent only—no bleach or fabric softeners.
✔ Air dry or use low heat in the dryer to prevent cracking.
Bonus Tip: If the print ever feels stiff or wrinkled, a quick low-heat press (with parchment paper on top) can help smooth and restore it.
