What is the working principle of a videojet thermal Transfer printer(TTO)?

Videojet TTO coding machine uses thermal transfer technology to transfer ink from a ribbon onto a substrate, such as films, labels, and packaging materials. The ribbon is made of a thin film coated with a layer of ink on one side. The ink is melted onto the substrate through the application of heat from the printing head.

The printing head of videojet TTO coding machine is made up of a series of heating elements that are arranged in a row. When activated, the heating elements generate heat and melt the ink on the ribbon. As the substrate passes beneath the printing head, the ink is transferred onto the substrate, forming characters, symbols, or barcodes.

To ensure accurate and consistent printing, videojet TTO coding machines use sensors to monitor the position of the substrate and adjust the printing head accordingly. The sensors detect the presence of the substrate and provide feedback to the control system, which adjusts the printing head’s position and timing to ensure accurate and precise printing.

One of the key advantages of videojet TTO coding machines is their ability to print high-quality and durable markings on various substrates. The printing quality is dependent on the quality of the ribbon and the printer’s settings, such as the temperature and speed of the printing process.

In summary, videojet TTO coding machine uses thermal transfer technology to transfer ink from a ribbon onto a substrate, utilizing a printing head that is composed of heating elements to melt the ink. The substrate is precisely positioned by sensors to ensure accurate and consistent printing. videojet TTO coding machines are widely used in various industries, including food, pharmaceuticals, cosmetics, and beverage packaging, due to their high-quality printing, speed, and efficiency.
