Measurement of Toner Cohesion in Liquid Inks Using a Visualization Cell
Using the visualization cell, we have examined the behavior of different liquid toners. We have observed the effects of different charge directors and their concentrations, as well as of different toner resins. While the cohesion varies according to the types of resins and of charge directors, there is no significant change in the behavior of the inks when charge-director concentrations are varied from a charge-director-to-toner weight ratio of 10mg/g to 50mg/g. We analyze the results with simple physical models that give a semiquantitative picture of the plastic behavior of inks at high particle fraction, up to the typical toner percentage of an image.

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.
