Fixation of Pigmented Black Ink on Matte Coated Ink-Jet Substrates
This study focuses on the properties of the materials used in microporous coatings for ink jet media and how they impact the media's interaction with pigmented ink jet inks. Material properties such as pore volume and particle size are studied, also binder types, additives, and ratios such as pigment to binder ratio and the ratio between hydrophilic and hydrophobic binder materials. For print evaluation an HP Designjet 100+ was used and methods were developed to evaluate the quality of pigment ink fixation. SEM analysis and dynamic contact angle measurements were used to analyze ink-media interactions.
The study showed that the formation of an ink pigment filter cake on the coating surface correlated to poor black fixation and in contrast, when no filter cake exists the fixation is good. Good fixation results are achieved when the dynamics of ink absorption into the media coating prevent the formation of a pigment filter cake on the surface.

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.
