Thermal transfer overprint, also known as TTO (Thermal Transfer Overprinting), is a printing method commonly used in packaging and labeling applications. It is a type of digital printing technology that allows for high-resolution printing of variable data, such as barcodes, expiration dates, lot numbers, and other product-specific information.
In thermal transfer overprint, a thermal transfer printer is used, which consists of a print head and a ribbon. The print head contains a series of tiny heating elements that heat up specific areas of the ribbon. The ribbon is coated with a wax or resin-based ink on one side.
During the printing process, the printer applies heat to the selected areas of the ribbon, melting the ink and transferring it onto the substrate, such as a label or flexible packaging material. The heated elements on the print head create a pattern of dots, forming the desired characters or images on the surface.
Thermal transfer overprint offers several advantages over other printing methods. It allows for on-demand printing of variable data, enabling customization and flexibility in labeling products. It produces high-resolution prints with sharp and durable images, ensuring good legibility and barcode scannability. The technology is also versatile and can be used on various packaging materials, including paper, cardboard, films, and foils.
Overall, thermal transfer overprint is a reliable and efficient printing method used in industries where precise and variable data printing is required, such as food and beverage, pharmaceuticals, logistics, and manufacturing.
