If you require an all-over print, generally a process called dye sublimation printing is required.
This does in turn mean we wouldn’t be able to print your design onto Fairtrade organic cotton t-shirts; as It is not possible to sublimation print onto cotton garments. The sublimation inks do not stick to cotton, and only stick to polyester.
Therefore it would need to be a polyester t-shirt we’d need to use for your printing.
As polyester is a synthetic fibre, this cannot be certified as organic or Fairtrade.
