Plastisol Screen Printing Ink | Dynamic Low-Cure & LB Inks | Lawson

What is plastisol ink and why is it popular for screen printing?
Plastisol ink is a PVC‑based ink that sits on top of the fabric, producing opaque, vibrant prints with great durability and wash resistance, which is why it’s the industry standard for t‑shirt printing.

What is the advantage of low‑cure plastisol ink?
Low‑cure plastisol inks like Dynamic low‑cure formulas cure as low as 270–300°F, helping prevent dye migration and fabric scorching on 100% polyester and heat‑sensitive blends.

When should I use low‑bleed (LB) plastisol ink?
Use low‑bleed (LB) inks when printing on polyester or poly‑cotton blends, especially darker shirts, to stop garment dyes from bleeding through the ink layer during curing.

Can I match Pantone colors with your plastisol inks?
Yes. Lawson’s Multi‑Match color‑matching system and Dynamic mixing inks let you mix accurate Pantone colors using specific primaries and formulas for consistent results.

What mesh counts work best with plastisol ink?
Most standard plastisol prints on t‑shirts use 110–160 mesh; you might choose lower mesh for heavy whites or glitter and higher mesh for fine detail or softer prints.

How do I cure plastisol ink correctly?
Plastisol must reach full cure temperature all the way through the ink film—typically around 320°F for standard plastisol and lower for low‑cure versions—verified with a temperature probe or test strips.

Do you offer support on choosing the right plastisol ink?
Yes. Lawson can help you choose between RFU, low‑cure, LB white, fluorescent, and specialty inks, with technical support available from our teams in St. Louis, Missouri and Marietta, Georgia.
