UV Lamp Design for Moving Print-head Inkjet Applications
Abstract:With the advent of Piezo ‘drop on demand’ print-heads and the development of “jet-able” UV curable ink systems, the past 5 years has seen a dramatic uptake in the marketplace of UV inkjet. This growth has, (and continues to be), in both static and moving print-head applications. Visit any current graphics show and examples abound with modern roll to roll or flatbed scanning printers producing; banners; POP displays; printing onto glass, wood, & ceramics; as well as static high speed addressing systems; identity and security card printing; and CD printers.
So was this an easy transition for UV lamp technologies to take from offset, screen, flexographic or any other traditional application?
Certainly ink developments in the laboratory were all carried out using known lamp designs, however these did not always translate to the practical machine. Static applications have been able to fairly readily adopt existing UV lamp system technologies (suitably adjusted for the process requirements) however the moving head X-Y plotters/ grand format industrial graphic printers initially struggled to find appropriate lamp units, mainly due to problems of weight and size but also because of other unique requirements.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
