Analysis of Contact Pressure Acting on a Thermal Print Head of a Thermal Transfer Printer

The printing method of the thermal transfer printer is to push an ink ribbon that is heated and melted by a thermal print head to a printing paper, and transfer the ink desired positions on the paper. Thus it is important to place the heater of the thermal print head at the position where the contact pressure is most high. The visco elastic properties of the ink, PET and platen rubber were measured with a rheometer. The contact pressures on the...
