Tee Junction uses Direct-to-Garment printing with Oeko-Tek certified water-based inks 

What is DTG (Direct-to-Garment) Printing?

Also commonly referred to as 'Digital Printing', DTG is relatively new to the world of apparel printing (around 15 years). Tee Junction was one of the pioneers and first every company in the world to offer complete DTG printing solutions for custom t-shirts and apparel.

The concept of DTG works similar to a home inkjet printer. The design is set up on the computer (a PNG file is recommended), and the software sends the design to the DTG printer, where waterbased CYMK (Cyan, Yellow, Magenta and Black) ink is printed directly onto the garment.

On white garments, Tee Junction applies a pretreatment onto the fabric, much like a primer before you paint a house. The CYMK ink is then printed directly onto this pretreated fabric.

On coloured and black t-shirts, the process is more involved. This time, a stronger pretreatment is applied to the fabric of the shirt. The next step is the 'white underbase', where white ink is applied to all areas where the design will be. This white ink provides the 'canvas' for the colours to print onto; otherwise, the colours would not be seen on dark coloured shirts (since the waterbased inks are translucent, not fully opaque). Once the white underbase is applied, the garment is fed back into the printer, and the CYMK design is printed on top of the white ink.
