Ink migration to the trailer from a rolled ribbon designed to print wit lift-off correction capability is avoided by using polyethylene terephthalate as the trailer material. The ribbon typically comprises phenolic-based polyamide resin, mineral oil, plasticizer of mixed esters of fatty acids, and pigments, these four parts being in roughly equal amounts by weight and coated on a polyethylene substrate.
