Clive Ayling, managing director at Meteor Inkjet Ltd, discusses how printer driver electronics are increasingly adapting to an ever-demanding market and how good design is critical to high performance inkjet printing.
Erwin Hijzen, Program Manager MEMS & Micro Devices for Philips Innovation Services, gives an introduction to their innovative capacative MEMS actuator technology and its use in medical and inkjet applications.
Prof J. Frits Dijksman of the University of Twente explains the basic principles of fluid mechanics behind the operation of an inkjet printhead, comparing it with a musical instrument.
Mike Willis of Pivotal Resources looks at the new printhead from Xaar and its likely position in the market.
Part 1 of a review of the IMI Europe Inkjet Printing Conference 2015.
One talk at the IMI Europe Ink Jet Conference is from Konica Minolta, who will be discussing their new silicon MEMS printhead technology.
Mike Willis, Managing Director of IMI Europe, reminisces about the beginnings of a leading inkjet printhead manufacturer.
With the apparent demise of Olivetti in Italy as a source of thermal inkjet heads, it was very interesting to learn of developments from Taiwan at the recent 21st European Inkjet Conference run by IMI Europe in Lisbon, Portugal. One of the speakers, Dr Daniel Lan, Managing Director of IUT, described their experience in developing thermal inkjet technology. This began at ITRI in 1993 and R&D led to the formation of three manufacturing spin-offs. IUT has manufactured 11 million ink jet printhead cartridges over 13 years, and since 2004 a major shareholder has been Asus.
Dr Lan explained that what they have been able to offer in the past has been restricted by patents, particularly those from HP. Although they were convinced their technology worked around IP restrictions, the cost and timescales of challenging any legal action was prohibitive. But that may change next year when in late 2014 a significant number of fundamental patents, including matrix addressing, over-edge ink supply and nozzle densities greater than 300 dpi expire.
In addition IUT is developing some new printheads. Special materials are being evaluated to allow solvent inks to be used. And 2 and 4 inch wide heads are being developed. These are intended for fixed array single pass applications.
