Influence of Printhead Geometry, Print Conditions and Fluid Dynamic Properties on the Jetting Behaviour
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.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
