Abstract

The importance of dye partition coefficients in thermal dye transfer printing efficiency is demonstrated by computational modeling, direct experimental measurements of dye partition coefficients, and printing efficiency measurements. Previous calculations of the effects of printing power, print head efficiency, line time, and media materials properties using the onedimensional LaFleche-Ozimek model have predicted that a higher dye partition coefficient P should lead to higher thermal dye transfer printing efficiency. However, little or no experimental data on receiver/donor dye partition coefficients have been reported. In this work we report direct experimental measurements of dye partition coefficients for various dye/binder combinations. Values for P ranging from 0.24 to greater than 10 were obtained. Thermal printing efficiency is observed to increase with increasing partition coefficient, in agreement with the LaFleche-Ozimek model.
