A Study of the Dynamic Spreading of Inks onto Various Ink-jet Substrates
In this study, several substrates, including papers of various quality levels and a polymer film, were analysed. Classical methods of porosity determination were applied, together with roughness measurements. The surface energy of these substrates was calculated from measurements of contact angles with various liquids.
A series of commercial ink-jet inks, and the corresponding model solvents were analysed. Their surface tension was measured by the DuNouy ring method and then,.their spreading kinetics onto the different substrates were examined using a high-speed camera coupled with an image analysis system.Various situations were observed. These results were correlated to quality tests conducted with commercial ink-jet printers using the same inks/ substrates systems.

For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
