A two-dimensional finite-element model for dye diffusion thermal transfer printing has been developed, in which partition coefficients are included. Experimental data of the partition coefficients and the dye diffusion coefficients are used in the model. Dye concentration after printing is not always continuous at the interface between the dye-coated layer and receiver-coated layer in the model. The stability of the computer calculation has been checked from various points of view. The optical density prediction shows good agreement with the experiments. The model has been applied to the calculation of the amount of transferred dye when the physical parameters of the medium are varied. It is concluded that the most important factors for increasing the amount are the dye diffusion coefficients and the partition coefficients.
