Use a nylon or plastisol ink with a catalyst (hardener). Certain Poly Inks can work as well. Ask your ink supplier. Keep in mind a catalyst will shorten the shelf life of the ink leaving left over ink unusable as it will harden.
Use tight screens with 200+ mesh count to lay down a little less ink than would be used on tees (tees normally use a more open mesh like a 110).
Ink tends to sit on top of the surface of this fabric as opposed to pressing into cotton type fabrics.
A harder squeegee can help lay down less ink and help keep cleaner design edges.
Nylon fabric also tends to move more than tees on the printing pallet.
Sometimes a jacket clamp is recommended when doing multi-color prints.
Curing time and temperature will vary by ink types used on nylon fabrics.
VERY IMPORTANT to cure your ink at the right temperature without burning or shrinking nylon.
Nylon fabrics should usually be cured at temperatures under 320. Flash at low temperatures to keep from burning and/or shrinking fabric. (consult ink supplier and test).
Washing the printed sample garment(s) after 24+ hours (so hardener has set) is recommended to make sure you have proper curing and ink adhesion.
