With the formulation experiment to design the UV inkjet ink of different pigment/binder ratios, UV inkjet ink samples of different dispersions are prepared. The size and distribution of pigment particles and UV absorption spectrum of the samples are then tested. The result indicates that: the pigment/binder ratio has a great impact on the dispersion of the UV inkjet ink, when the ratio is 2:1, the ink sample can obtain good dispersion; dispersion of the pigment particles affects the intensity of UV absorption of the ink system. The absorption spectrum has a strong dependence with the dispersion of ink. With the decreasing of the pigment particle size, the UV absorption intensity of the ink system increases. The main innovation of this study lies in the establishment of evaluating particle's dispersion according to the change of UV absorption spectrum of the ink system.

More about this publication?
  • 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.
