Rob- Ever wash a red 100% polyester garment in the wash with a white towl??? Even though the temperature of the polyester never comes close to reaching its sublimation temperature, the dyes are still released from the garment! The additives that give the ELT SERIES ink its best bleed resistance work in the 270-300F range ( and no this ink WILL NOT GHOST AT ALL!). We would never recommend running at the bottom temperature cure range of any ink series unless the garment or material dictate so. If someone turns on a fan, or opens an overhead door you may get just enough of a breeze through a dryer to not fully cure whatever you are running. As I stated above, sublimation dyes do not have to reach their sublimation temperature to want to leach into vinyl no matter if it is cad cut, or printed plastisol.
