Abstract:
The Arrhenius model is widely used in the accelerated aging studies to predict the durability of the properties of both paper and ink. In other words, this model intends to simulate the real-time aging. The Arrhenius model expected a linear relations between the reactions (K)depends exclusively on the temperature (T). This study demonstrates that the application of this model should not be one indiscriminately and there are several restrictions in some cases. In this study the Arrhenius model was used to predict the durability of printing made with thermal transfer ribbon and on thermal sensitive paper. The parameter used to monitor the accelerated aging was the optical density of the printed areas. In the case of the printing made with thermal transfer ribbon it was observed, at high temperatures, the degradation of the material that comes from the ribbon. This degradation occurs because of side reactions that are not observed under natural conditions of aging. In the case of printing on thermal sensitive paper the application off the Arrhenius model was also not applicable due to the restriction to high temperatures. Two critical factors for performing accelerated aging tests were identified in this study: the choice of test temperatures and the definition of acceptable yield loss for the focuses property.
