Why DTF Ink Clog Print Head and How to Solve Clogging Problem

Print head clogging is the main factor affecting the DTF transfer printing quality and yield. Major factors include:

1. Ink quality: Inferior quality, overly thick ink or impurities will clog the print head.

2. Ink drying: Premature drying in the print head affects normal jetting.

3. Lack of maintenance: Failure to clean print heads or replace cartridges regularly leads to debris accumulation.

4. Environmental factors: High temperature or low humidity (keep workshop humidity at 40%-80% and temperature at 15-30°C) cause fast evaporation and viscosity changes.

5. Ink system problems: Clogged filters or malfunctioning pumps prevent proper ink flow.

1. Use High Quality DTF Ink: Use premium, compatible inks like HONGSAM High Quality DTF Ink.

2. Clean the print head regularly: Clean once a week using specialized cleaning solutions or distilled water according to machine instructions.

3. Use a humidifier: Maintain an ideal environment humidity between 40% and 60% to prevent ink from drying out.

YES! White ink affects print heads in three main ways:

1. Print head clogging: White ink is thicker and heavier, easily hardening in the nozzle.

2. Print head damage: Its density causes higher mechanical wear and tear over time.

3. Mixed ink: White ink can contaminate other color lines in the ink system if improperly maintained.

HONGSAM DTF ink has passed ECO PASSPORT by OEKO-TEX^® and GOTS. It features balanced viscosity (3.0 - 5.0 mPa·s at 25°C), high chemical stability, and excellent wash fastness (Level 4.5+), extending printhead lifespan by approximately 30%.
