New Deinkable Water based Inkjet Inks
Abstract:Water based inkjet ink is a major challenge for the deinking process. This process is the key step in paper recycling. It has been designed to separate hydrophobic ink particles from hydrophilic cellulose fibers. In this process, soluble dyes cannot be removed; they stay and accumulate in the circulation water. Thus additional bleaching steps have been suggested to make up for the loss in brightness. However, bleach is not an option for the majority of paper mills producing newsprint and other graphic papers from the household mix. It is neither economical nor ecological as this would require to add equipment and to increase the use of chemicals as well as the chemical load of the effluent.
Therefore, other solutions look more sustainable: Inkjet inks that help to produce prints which perform as good as offset or dry toner prints in a standard deinking paper mill. Resin based inks seem to be a way to achieve this goal.

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.
