Because there are many labels, it must be able to withstand the test of time, long-term unchanged, the text must be stored for a long time, cannot fade, cannot wear due to contact with solvents, cannot deform or change color due to high temperature, etc., so it is necessary to adopt a special The material of the printing medium and printing materials to ensure these characteristics, the general inkjet printing technology can not achieve, laser printing can not be achieved, and the effect of needle punching and the original design can not meet the requirements, so there is the emergence of thermal transfer technology.
  Thermal transfer technology, to put it simply, is to use a special ribbon to transfer the toner coating on the ribbon to paper or other types of materials through a working principle similar to that of a fax machine print head. On the other hand, since the coating material on the carbon ribbon can be selected according to the needs, it produces strong adhesion, and the choice of the printing medium can better ensure that the printed handwriting is not affected by the outside world.
  The heating process, how to heat, can be controlled by the computer. Since various software specially used to print labels have been developed, it can be said to be very convenient for users, especially for general labels. Bar codes must be generated, and the generation of bar code symbols has therefore become an indispensable tool for this type of software.
