As one liter ink can print about 100 SQ.M, one set ink is 500ml per 5 color (C.M.Y.K.W), total is 2.5 liter.
For example, if you print on white t-shirt with logo size about 20*20cm, you can print about 2500 pcs white t shirt by one liter textile ink. So, 1 set textile ink can help you print about 6250 pcs white t-shirt.
