Abstract

<p>Evaluation of jetting durability, which is an important performance property of inkjet ink, requires a large amount of ink and a long period of actual evaluation. Especially for thermal heads, a destructive test of the head has been mandatory for evaluation due to scorching to the heater. In contrast, as a method to predict lifetime without actual jetting, our newly developed zeta potential measurement method and a potential energy calculation protocol based on the classical DLVO (Derjaguin-Landau-Verwey-Overbeek) theory using the obtained zeta potential values are used. A method for predicting jetting durability was found.</p>
