Fibre first: cotton binds, polyester does not
Water-based DTG ink bonds to cotton. On polyester it can pool, and on high-polyester blends the print looks washed out from day one.
A 100% cotton jersey is the safe choice. Blends can work at low polyester content, but at that point you are testing rather than producing.
Dark garments: pretreatment and underbase
On black and navy, the shirt is pretreated so the white ink will sit on the surface, then a white underbase is printed before the colour.
That adds steps and changes the result: a heavier hand and faster fading. If the design allows, print on a light garment instead.
- Light garments: no underbase, softer print, longer life.
- Dark garments: pretreatment + white underbase, heavier and shorter life.
- Heather and melange: the texture shows through — sometimes desirable, often not.
What ruins a DTG print
Fabric softener is the classic killer: it coats the fibre and the pretreatment cannot work. Sample garments should be washed without softener, or not washed at all before printing.
Moisture is the second: a damp shirt from a humid warehouse prints inconsistently. Good shops pre-press the garment before printing.
What we hold
23 styles, most 100% cotton jersey from 160 to 350gsm, from $3.00. The light-toned 180–230gsm range is what DTG shops tend to keep.
