Abstract

The invention provides a thermal transfer ribbon and a preparation method thereof. The ribbon consists of a substrate, a back coating and an oil ink layer, wherein the back coating and the oil ink layer are separately coated with the two sides of the substrate. The preparation method adopts a coating process. According to the thermal transfer ribbon and the preparation method thereof disclosed bythe invention, raw materials are simple, sources of the raw materials are wide, a low-carbon and environment-protection concept can be conformed, and expansion of the ribbon application fields is facilitated.

Description

technical field [0001] The invention relates to the technical field of thermal transfer consumables, in particular to a thermal transfer ribbon and a preparation method thereof. Background technique [0002] Thermal transfer printing is the process of using heat and pressure to transfer ink from ribbon media to paper or film, transferring the ink to the label as it passes through the printer's printhead and platen. [0003] Thermal transfer printing technology is to use a special ribbon to transfer the toner coating on the ribbon to paper or other types of materials through the working principle similar to the print head of a fax machine. The coating material on the belt can be selected according to the needs to produce strong adhesion, coupled with the selection of printing media, it can ensure that the printed handwriting will not be affected by the outside world. And this heating process, how to heat, can be handed over to the computer to control. At present, various sof...
