Practical Application of UV-LED Curing Technology to UV Inkjet
Abstract:UV-LED curing systems have started to play a larger role in many UV curing applications - including wide format and single pass UV inkjet – and their application and adoption will likely continue to accelerate over the next several years.
Adoption is increasing based on the wider availability of suitable UV-LED inkjet ink formulations. The inherent advantages of UV-LED technology - in terms of lifetime, consistency of output, instant on/off and lower heat production, as well as the possibility for systems that are smaller and more robust when compared to existing traditional lamp solution - makes it particularly attractive for UV Inkjet applications.
Just like all new technologies there are important differences, distinctions and choices that must be made if a successful implementation is to be achieved. UV-LED curing systems are not the same as traditional mercury vapor lamp systems and the issues of required irradiance/power output, measurement of irradiance/power and understanding of the effects and availability of wavelengths available today in UV-LED are key in making appropriate decisions about the suitability of the technology. These and other system level considerations will be discussed and the paper will outline several successful implementations of UV-LED for inkjet that are currently in the public domain.
The paper will also outline the challenges and will share some data and insight into the practical application and efficacy of newer generation UV-LED systems when applied to optimized inks sets for UV Inkjet applications.

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.
