An ink or coating composition is rheologically tested at three or more temperatures which substantially cover the anticipated range of printing operation temperatures expected to be encountered during printing to determine the value of the rheological parameters viscous modulus, phase angle and phase-angle slope, and to identify values of these parameters encountered during printing around which the structural behavior of the ink or coating changes. An ink composition that has a phase angle of at least 55°, a viscous modulus of at least 150 Pa, and a phase-angle slope of at least -0.5°/°C. exhibits low misting when em-ployed in high speed printing apparatus.

Une composition d'encre ou de revêtement est rhéologiquement testée à au moins trois températures couvrant sensiblement la plage attendue des températures du processus d'impression pouvant être rencontrées pendant l'impression, de façon, d'une part à déterminer les valeurs de paramètres rhéologiques, et notamment du module visqueux, de l'angle de phase et de la pente de l'angle de phase, et d'autre part à identifier les valeurs de ces paramètres rencontrées pendant le processus d'impression, valeurs autour desquelles le comportement structurel de l'encre ou du revêtement se modifie. En l'occurrence, une composition d'encre dont l'angle de phase est d'au moins 55°, le module visqueux d'au moins 150 Pa, et la pente d'angle de phase d'au moins -0,5°/°C, fait preuve d'une faible voltige de l'encre lorsqu'elle est utilisée dans un appareil d'impression à grande vitesse.
