Research on the Adherence of the Water-based Ink
Abstract:In order to improve the adhesion of water-based ink on substrate with low surface tension. Prepare ink samples of different dispersions with different kinds of dispersants and pigment/resin ratios and test their dispersion. Then prepare different ink samples with all kinds of film-forming resins and additives, measure the surface tension of the ink samples on the plastic which is used to characterize their wettability. Meanwhile use the IGT F1 printing eligibility instrument to make proofs with ink samples above. Discuss main factors that influence adhesion of water-based ink by analyzing wettability of ink samples. Research results indicate that: dispersion of water-based ink and resin have great influences on the adhesion on substrates with low surface tension; Right amount of adhesion promoter can effectively enhance the adhesion; The well wettability of ink on the substrates is the precondition to ensure adherence of the water-based ink.

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.
