The composition of the ribbon
- Apr 11, 2018 -

For the thermal transfer of the bar code printer, you need a special ribbon to print the bar code and text and other information on the label. This special ribbon (commonly known as the ribbon) is generally composed of a base film, a heat-resistant coating, and an ink coating. The base film is the carrier of the ribbon, generally 4.5μm thick polyester film, its strength, thickness directly affect the elongation rate of the ribbon and application areas; heat-resistant coating is the main role of heat insulation, reduce friction, reduce print Dust is attached to the head to protect the print head and extend the life of the print head. The ink coating consists of pigment, resin, wax, additives, etc. It affects the transfer temperature, print quality, color of the ribbon, The main properties of imprinting such as rubbing resistance are the core of the ribbon. Carbon black is commonly used in the black ribbon ink composition, which is why this ribbon is often referred to as a ribbon.

Thermal transfer ribbon working principle

The ribbon is on the thermal transfer printer. The heat-resistant coating is in direct contact with the thermal transfer head. The thermal transfer ink is in direct contact with the substrate (label). The heat transfer head instantly releases heat during operation, and the heat of the hot spot passes through the resistance. The thermal coating and the base film are transferred to the thermal transfer ink coating, and the ink is melted and hot stamped onto the substrate to form characters and images. The high-quality ribbon does not have thermal transfer ink residues in the heated portion after transfer.
