Abstract: A method providing for the replacement of the traditional back coat of thermal transfer ribbons or dye sublimation ribbons uses a plasma treatment to chemically modify the print head side surface of a PET substrate of the ribbons. The chemically modified surface of the PET substrate provides the necessary heat resistance and coefficient of friction to allow the thermal print head to function properly without burn-through of the PET carrier film and without sticking to the thermal print head. Accordingly, plasma treated thermal transfer ribbons or dye sublimation ribbons can be made without a back coat.

Abstract translation: 提供替代传统背面传热带或染料升华带的方法使用等离子体处理来化学改变色带的PET基底的打印头侧表面。 PET基板的化学改性表面提供了必要的耐热性和摩擦系数，以允许热敏打印头正常工作，而不会导致PET载体膜的燃烧而不粘附到热敏打印头。 因此，可以在没有背涂的情况下制造等离子体处理的热转印带或染料升华带。
