Thermal Transfer Overprinting Working Principle
Thermal transfer overprinting is a printing process requires a thermal transfer printhead(TPH) and ribbon to contact the packaging material. And there are two working methods of thermal transfer printing: intermittent and continuous
Step 1. The tiny heating point of TPH enables printing to reach a printing resolution of 300 dpi (12 dots/mm).
Step 2. The ink on the ribbon is melted by instant heating and then transferred to the packaging material.
Step 3. Printing can be formed on the packaging material through the relative movement of the TPH and the ribbon and the packaging material.
Step 4. Intelligent control enables the heating point to print various contents on the packaging materials.
