There is much activity on inkjet printing of functional materials, and many very impressive and encouraging results on a small scale have been shown. But the real applications for such achievements will generally require printing at a much larger scale, and there are many challenges in scaling a successful process at laboratory scale to a successful one at industrial scale.

Inkjet printing is inherently scalable, which is a key advantage for solution processable P-OLEDs and their use in manufacturing large, commercially-relevant displays. But there are many aspects to consider in scaling up including time, process factors, dealing with large arrays of nozzles and large printers, and robustness.

This paper addresses some of these issues, and raises awareness of others with particular reference to display printing - methods to combat swathe joins are still applicable, print strategies can be used to generate redundancy in arrays to mitigate lost nozzles or nozzle variations, and physical structures can be changed to makes processes more tolerant of drop misplacement.

  • 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.
