These Texsource Polyester Inks are designed for use with cotton/polyester blends, 100% polyester, or stretchable poly fabrics; garments which can be difficult to print on due to their flexible nature and a process known as dye migration, where dye from polyester fibers is released into your ink when cured. Using specially formulated Texsource Polyester Inks makes printing these types of garments easy by helping to avoid these common problems.
