Thermal Transfer Coders
Thermal transfer print heads are semiconductors, which house a row of tiny printing
elements approximately 300 per inch that are housed within a ceramic coating. The
thermal transfer ribbon is a thin film, which is coated with a waxy ink-resin on
one side. When the print head makes contact with the non-inked side of the print
ribbon, the print elements are heated and cooled in rapid succession. When heated,
the elements melt the ink, transferring it to the print media. The elements cool
and the media is moved so that the next line can be printed. Thermal transfer coders
can print real-time information, graphics, and bar codes and can use a variety of
stationary or moving print media, making it perfect for continuous packaging lines
as well as intermittent applications. Intermittent applications such as self-adhesive label applicators the print media
is stationary, the print head come in contact with the ribbon that then comes in
contact with the print media. The print head moves over the ribbon, completing
the printing process. Continuous applications the print head fixed. The printer head lowers and contacts
the ribbon and substrate. It is then the motion of the ribbon that completes the
printing process, not the print head. With this process, the ribbon and print media
are calibrated to move at the same rate, producing top quality images. Thermal transfer coders are a digital technology that can automatically updated
lot codes and best-before dates, reducing the risk of operator error. Thermal transfer
coders work in combination with several varieties of continuous-motion and intermittent-motion
packaging machinery.
