Thermal Transfer Overprinting is a printing commonly used in the packaging industry to apply variable data such as date codes barcodes, and product information on flexible packaging materials. TTO printers use a thermal printhead to transfer ink from a ribbon onto the packaging substrate, providing high-resolution, high-quality prints with excellent durability. TTO is preferred for its versatility, fast printing speeds, and ability to handle a wide range of substrates, making it an ideal choice for industries such as food and beverages, pharmaceuticals, and cosmetics.
