Thermal Transfer Technology: Latest Buzz in Print Packaging Industry

Thermal Transfer Technology is the latest addition in the print packaging industry. A thermal transfer ribbon and a thermal print head are used in this method. The printhead is made of a ceramic-glass component that contains 12 thermal printing dots per mili meter. It delivers 300 dpi print resolution. The thermal printhead is used to prepare the print information. The printing dots are then heated according to requirements. It helps to transfer the colored pigment from the foil to the material on which the printing will be done.

Thermal Transfer Technology is very cost effective because the Thermal Transfer Overprinters are absolutely free. They can produce variable data for each and every print. With the help of the high-resolution printhead one can print text, batch numbers, graphics, bar codes as well as real-time dates. This printing technology enables you to print on the packaging materials directly. As a result you don’t need any label. So the cost per print gets reduced. This is the major reason that thermal transfer has become the most popular print packaging technology.

For each print, a minimal amount of ribbon is used. This makes the thermal transfer technology an economical solution for the print packaging industry. This technology can be used for packaging coding for top foils, sachets, seal machines, form fill, continuous films, packaging films and similar products.

Thermal transfer technology for printing can be used for two types of printings such as intermittent printing and continuous printing.

Intermittent printing technology is used on lines that move in an intermittent or start/stop motion. In this technology a signal from the packaging machine is used to prepare the print information. The printhead is set on a back plate and then it is moved across the printing surface. As soon as the print is complete the printhead returns to its initial position and the product is released.

Continuous printing technology on the other hand is used for continuous flow lines. The film moves when the packaging material gets printed. The packaging machine gives a signal. Then the printhead is forced down on the platen roller. The roller gets integrated into a bracket frame to start the printing process. You can expect a clear print image since the print speed gets adjusted automatically.

Thermal transfer technology is undoubtedly the ideal choice for custom printed packaging because of the high quality printing it offers and because of its cost effectiveness.
