Frequently Asked Questions — DTG Printer Ink
What is the difference between DTG ink and DTF ink?
DTG ink is formulated to print directly onto natural fabrics like cotton and linen, requiring pre-treatment for white ink to bind properly. DTF ink is printed onto a PET film, covered with hot melt adhesive powder, and heat-transferred onto the garment. DTG inks typically yield a softer, more breathable feel compared to DTF prints.
Do I need to pre-treat dark cotton fabrics when using white DTG ink?
Yes. When printing with white DTG ink on dark-colored cotton garments, applying a liquid pre-treatment solution is mandatory. The pre-treatment acts as a chemical primer that instantly solidifies the white ink droplets on the fabric surface, preventing the ink from sinking into the fibers and bleeding.
What are the heat curing requirements for DTG printing inks?
After printing, the wet textile pigment ink must be fully cured to become wash-durable. Using a standard heat press, cure the ink at 160–165°C (320–330°F) for 90 to 120 seconds under light to medium pressure. For high-volume production, a commercial conveyor belt dryer can be used at synced speeds.
How do I prevent white DTG ink from clogging my printer's printhead?
White ink contains titanium dioxide, which settles over time. To prevent clogging, ensure your DTG printer is equipped with a white ink circulation system. Additionally, gently shake the white ink bottles daily before printing, and perform routine printhead cleaning cycles to keep the nozzle channels moist and clear.
What is the shelf life and storage conditions for DTG inks?
Colored DTG inks (CMYK) have a shelf life of up to 12–18 months, while white DTG ink has a shelf life of 6–12 months due to settling characteristics. Inks should be stored in a cool, dry place out of direct sunlight, with temperatures maintained between 15–30°C (59–86°F).
