The printing method of the dye sublimation printer is to push and heat a dye-based ribbon by a thermal print head, and diffuse the ink dyes to desired positions into the receiving layer of a paper. If the thermal print head was not in right position, degradation of the printing quality occurred because of less pushing force on a micro-heater. Thus, it is important to place the micro-heater of the thermal print head at the suitable position where the printing quality becomes high. This positioning region is called "positioning margin for thermal print head." In this paper, it was confirmed that the positioning margin was affected by the load applied on the micro-heater of the thermal print head. And we proposed a new method of determining the positioning margin using a numerical analysis on the basis of the contact pressure distribution.
