What is a barcode

Carbon ribbon Barcode ribbon is a consumable used in barcode printers. It is a polyester film coated with wax-based, resin-based or mixed ink on one side. Lubricant is applied on the side without ink to prevent printhead wear. The ink on the tape is transferred to the label by the heat and pressure of the print head of the barcode printer. The shaft cores of bar code carbon ribbons are usually paper and plastic. The main requirements are that they cannot be deformed and cannot slide during printing.

Good barcode ribbon can protect the print head, the printing effect can be accurately attached to the label, it is not easy to spread, and it is not easy to fall off.
