Ink dries naturally, but when printed T-shirts are washed, the printed areas may fade.
For fabric materials with more than 50% cotton, after the ink dry naturally, heat-setting it with an iron at 150℃ for more than 1 minute will make it more resistant to washing..

<Additional information>
The base color is difficult to see when overprinting on dark colored fabric or with dark colored ink making the ink color appear more vibrant.

Anti bleeding*2:
Bleeding is the phenomenon where the dye from polyester fibers transfers to the ink and caused discoloration during heat setting.
Resistance to dye migration means that this phenomenon is less likely to occur.
For example, if you print white on dark red polyester fabric, the white color becomes slightly pinkish.
Also, if you print black on dark red polyester fbaric, the dye will be transferd and the color
change will not be noticeable.
Therefore, the lighter colored ink will be affected by the dark colored polyester fabric,
and If you use dark ink on the lighter colored polyester fabric, the effect will be less noticeable.
