    • A thermal transfer printing method which is performed by the use of a thermal printer including a platen, a thermal print head having at least one heating element and a length of ink carrier ribbon with the recording medium positioned between the thermal print head and the length of ink carrier ribbon, which ink carrier ribbon having a base film and an ink layer, which method includes the steps of pressing the ink carrier ribbon against the platen by the thermal print head with the ink layer brought in contact with the recording medium, heating the heating element to cause that portion of the ink layer, which is aligned with the heating element, to fuse, and causing that portion of the ink layer so fused to partially transfer onto the recording medium when a cohesive force acting internally of the ink layer becomes smaller than an adhesive force acting between the ink layer and the recording medium and, at the same time, smaller than a adhesive force acting between the ink layer and the base film, whereby the cohesive force is substantially destroyed so as to permit the thickness of the ink layer to be substantially split into halves such that one of the halves is transferred onto the recording medium and the other of the halves remains adhering to the base film.
    • 一种热转印打印方法,其通过使用包括压板的热敏打印机,具有至少一个加热元件的热​​打印头和墨水载体带的长度来执行,记录介质位于热打印头和长度为 墨水载体带,该墨水载体带具有基底膜和墨水层,该方法包括以下步骤:通过热敏打印头将墨水载体带压靠在压盘上,墨层与记录介质接触,加热 加热元件使得与加热元件对准的油墨层的那部分熔化,并且当在油墨层内部作用的内聚力变为 小于在油墨层和记录介质之间作用的粘合力,并且同时小于作用在油墨层和第二层之间的粘合力 e基膜,由此内聚力基本上被破坏,以便允许油墨层的厚度基本上分成两半,使得其中的一半转印到记录介质上,另一半保持粘附到基底 电影。
