Thermal transfer ribbon refers to the ink ribbon coated wax base, resin or polyester mixed ink or other high density film. The printing head of the bar code printer can be prevented from wearing or damaging by applying the lubricant on the side of the ink. Hand in hand and the former lead in the ribbon front, after gubernaculnm in volume at the end of the ribbon, but some are not after the lead.
A thermal transfer ribbon
The former general gubernaculum is transparent or other color, before the lead belt is easy to use, so it is convenient to install the ribbon bar code printer. Moreover, a general businessman can print the name of the product, the name and the trademark of the company on the front belt, so that it is more convenient for marketing and promotion. Is to be used to protect the ribbon before the lead has an important function.

The original barcode ribbon belt generally consists of five layers, including top coating, ink layer, inner coating, base and back. Among them, the ink layer is the most important, is mainly used to print and decided to use the characteristics of the ribbon, such as anti chemical corrosion and anti friction etc.. The inner coating is mainly used to make the surface of the printing smooth and the consistency of the ink released from the base. The top coating is mainly used to improve the adhesion of the ink on the bar code label paper to enhance the resistance of the bar code to the environment. Back on the back is a ribbon coating a layer of special coating, mainly is used to reduce the wear of bar code printer head, reduce static electricity and improve heat conduction. The band base refers to the carrier of the other layers and determines the performance of the heat conduction between the layers.

After the lead is a warning to the general is to the end of the induction bar code printer ribbon. Different bar code printers determine the different rear lead bands. The aluminum lead is mainly for the reflective type sensor, the reflected light appeared on the end of said ribbon. After the transparent lead is mainly used for sensor transmission, allowing light through the case said ribbon run out
