Abstract
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 employed in high speed printing apparatus.
