Technical Field

Background
The thermal transfer technology is a product of a combination of heat transfer principles and hot stamp technology, and among thermal transfer bar code printers manufactured according to this technology, the most common is a "melt" thermal transfer printer. It is the most commonly used industrial printer, which uses a polyester film as the base band of the ribbon, and coats the surface with a waxy solid ink. When printing, the microprocessor controls the heating body in the thermal (sensitive) printing head to heat, so that the hot-melt ink layer on the film color belt is melted, and then transferred to the plain paper to generate the pattern which can be kept for a long time. Because the film ribbon overcomes the network structure of the ribbon of the fabric commonly used in the dot matrix printer, the printed graph has a solid feel and is much like a printed matter. Thermal transfer printing is the process of transferring ink from a carbon tape medium to paper or film using heat and pressure, and transferring the ink to the paper as it passes through the print head and platen of the printer.
In the current thermal transfer printer, the winding and unwinding of the color ribbon are all exposed outside, and the color ribbon on the color-releasing ribbon roll needs to be manually wound on the color-receiving ribbon roll before printing, so that the operation is very inconvenient due to limited space.
