DTF Troubleshooting FAQ
Solutions to common DTF printing problems including transfer adhesion issues, print quality defects, ink problems, and equipment troubleshooting.
Why is my DTF transfer not sticking to the garment?
Common causes: temperature too low (should be 300-330°F), insufficient pressure, pressing time too short (10-15 seconds needed), old or moisture-damaged powder, or garment has moisture. Pre-press the garment for 3 seconds to remove moisture before applying.
Why are my DTF prints showing white lines or banding?
Banding is caused by clogged nozzles, misaligned printhead, or dirty encoder strip. Run a nozzle check first. If nozzles are clogged, run 2-3 head cleaning cycles. Clean the encoder strip with a lint-free cloth. If banding persists, check printhead alignment in your RIP software.
Why is my DTF transfer cracking after washing?
Cracking is usually caused by under-curing the adhesive powder, pressing at too low a temperature, or not pressing long enough. Ensure you cure at the manufacturer-recommended temperature and press at 300-330°F for a full 10-15 seconds with firm pressure.
Why are my DTF print colors wrong or washed out?
Check your ICC profile settings in the RIP software. Ensure you are using the correct profile for your ink and film combination. Verify white ink is flowing properly — weak white underbase causes washed-out colors on dark garments. Check ink levels and expiration dates.
How do I fix white ink clogging in my DTF printer?
Run the white ink circulation system regularly (every 4-8 hours). If clogged, run 3-5 head cleaning cycles. For severe clogs, use a printhead cleaning solution soak (15-30 minutes). Replace dampers if cleaning does not resolve the issue. Never let white ink sit idle for more than 48 hours.
Why is my DTF transfer peeling off after pressing?
Peeling indicates poor adhesion. Check that adhesive powder was applied evenly to all printed areas. Ensure the powder was properly cured before pressing. Verify heat press temperature, time, and pressure. Some fabrics with water-repellent coatings resist adhesion.
