Solve DTF printing problems and improve production efficiency
DTF printing is an efficient and flexible printing method. There are several common problems:White Ink Layering ; Ink Smears or Spills ; The Ink Response Is Unstable and the Pattern Is Distorted ; Transfer Film Is Jammed or Does Not Feed .
White Ink Layering Problem
Cause Analysis
White ink precipitation: The pigment particles in white ink are large and prone to precipitation when left unused, causing stratification.
Uneven stirring: Inadequate mixing directly affects print quality.
Solution
Shake regularly: Thoroughly shake the white ink before use. An electric stirrer is recommended.
Timed stirring system: For long-running equipment, install a timer stirrer to prevent sedimentation.
Maintain equipment: Clean ink lines and printheads regularly to ensure smooth ink flow.
Ink Smears or Spills
Cause Analysis
Clogged or misaligned printheads: May lead to dripping or uneven spraying.
Fabric handling issues: Stacking when hot may cause smearing.
Environmental factors: High humidity or low temperature affects ink curing.
Ink flow settings: Excess or insufficient flow causes smears or gaps.
Solution
Clean regularly: Use cleaning fluid weekly or as needed.
Calibrate nozzles: Use built-in printer functions to adjust spray patterns.
Handle fabric properly: Let prints cool before stacking or packaging.
Optimize environment: Control room humidity and temperature.
Adjust ink flow: Match flow rate to material and print speed.
The Ink Response Is Unstable and the Pattern Is Distorted
Cause Analysis
Unstable ink formulation: Low-quality ink may contain inconsistent pigments.
Viscosity issues: Ink stored improperly or expired affects spray behavior.
Material mismatch: Incompatible films may lead to peeling or fading.
Solution
Use high-quality ink: Select reputable brands with stable formulations.
Check expiration: Always verify ink freshness.
Select the right film: Use appropriate DTF film with uniform coating.
Transfer Film Is Jammed or Does Not Feed
Cause Analysis
Incorrect tension: Loose or tight film tension disrupts feeding.
Feeder system malfunction: Dusty rollers or aging parts hinder smooth operation.
Solution
Adjust tension properly: Ensure stable and smooth feeding.
Clean rollers and trays: Regular maintenance reduces friction and paper jams.
Replace worn components: Inspect and swap out damaged or aged feed parts.
