Energy curable inkjet inks are susceptible to build up of cured material at the nozzle where ink is ejected, which leads to jet deviation and ultimately lost jets. This causes a reduction in image quality and the need to replace the printhead. Traditional stabilizers do not reduce the susceptibility of energy curable inkjet inks to stray light or if they do, cure is compromised. It has been discovered that nitroxyl stabilizers will significantly reduce the build up of cured ink caused by exposure to low levels of UV light from stray light sources without compromising cure speed. In this paper a new test method for assessing the stray light resistance of energy curable inkjet inks is detailed. The major types of stabilizers are described and their effect on stray light resistance and cure for UV curable inkjet inks is determined.

  • 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.
