What is the common sense of thermal transfer ribbon?

 

Best Swing Heat Press Machine.jpgFor thermal transfer bar code printers, a special color band is required to print information such as bar codes and text on the label. This special ribbon is generally composed of a base film, a heat-resistant coating, and an ink coating. The base film is a carrier of the ribbon, and a polyester film of 4.5 μm thick is generally selected, and its strength and thickness directly affect the elongation of the ribbon and the application field; the main functions of the heat-resistant coating are heat insulation, friction reduction, and printing reduction. The head is stained with dust to protect the print head and extend the life of the print head. The ink coating consists of pigments, resins, waxes, additives, etc. It affects the transfer temperature of the ribbon, the print quality, the color of the ribbon, The main performance of the imprint's abrasion resistance is the core of the ribbon. The commonly used black ribbon ink has carbon powder, which is why this ribbon is often called the ribbon.


The carbon ribbon is on the thermal transfer printer, the heat-resistant coating is in direct contact with the thermal transfer head, and the thermal transfer ink is in direct contact with the substrate label. During operation, the thermal transfer head is instantaneously exothermic, and the heat of the hot spot is passed through the heat-resistant coating. The layer and the base film are transferred to the thermal transfer ink coating, and the ink is melted and burned onto the substrate to form characters and images. The high quality ribbon has no residue of the thermal transfer ink in the heated portion after its transfer.
