Rutland NPT FF Fluorescent Lemon Yellow M3 4042 Plastisol InkM3 Ink Mixing System is a non phthalate finished ink mixing system. M3 colors directly replace the M2 and EM ink mixing colors. They are opaque resulting in excellent coverage on dark garments. The tack free formula allows printing through a range of mesh counts without the need for a viscosity modifier. Use a white underlay when printing on dark fabrics for that extra pop in brightness. No build up formulations ensure the highest print efficiencies
