Abstract

This paper investigates key dynamic properties of the ink, at the timescale relevant to the inkjet printing, that can differentiate between good and bad inks which otherwise looked identical. An “Ink fluid map” is created for specific printhead which take account of the printhead geometry, jetting conditions and ink's bulk and key dynamic properties. This paper presents case studies whereby the “ink fluid map” is utilised to (i) identify optimum printhead geometry and print conditions (velocity, print frequency and temperature) for a given ink; (ii) formulate/recommend ink that meets both bulk and dynamic properties for reduced misting, satellite formation and improved reliability.
