UV curing inks based on 100% solids free-radical chemistry are finding increasingly wide application in inkjet printing. Such inks offer high jetting reliability and multi-purpose end-use properties, and much ink development effort has gone into these two requirements. However, a third but perhaps equally important requirement has not previously received the same attention – image quality.

Substrate, printing process and ink formulation variables may all play a key role in controlling image quality. However, whilst more established ink technologies such as water and solvent based inks will dry by penetration or evaporation, the drying mechanism for UV curing inks is quite different requiring a new understanding of the role of the UV ink formulation in image quality. This paper examines some of the issues from the perspective of UV curing inks, and looks at how tuning the chemistry of the ink formulation could modify image quality in a variety of applications.

In addition, there is a huge number of substrate and process variables in the latest UV curing inkjet applications, together with a frequent need to match the appearance of the printed output to conventionally printed materials. Improved understanding of the link between UV ink formulation and image quality will become part of a more generic approach to coping with this complexity. Ultimately, success in this area could help speed up the time to market of new UV curing inkjet printing systems.

  • 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.
