From Formulation to Fill
Ink Jet Ink Development and Manufacturing

Tuesday 9th - Thursday 11th July 2002
£750 or Eur.1,200 per registrant, including two nights accommodation and all meals
The popular course The Ink Jet Academy provides a good background of the types of ink jet inks and materials that are used in today’s ink jet printers. But how are inks actually made? Why does coloured water cost up to $2,000 per litre? Is pigmented ink really more expensive to make than dye-based ink? What is involved in manufacturing advanced ink jet inks?

This course is designed for those wishing to develop, source or commission the develop-ment and manufacture of ink jet inks. It will help you understand the issues of development and testing, scale-up for manufacture and the manufacturing processes themselves. As well as being of interest to ink jet technologists, managers will benefit from an understanding of the ink jet ink manufacturing process to set realistic project and revenue plans and to decide whether to manufacture in-house or externally source ink.

Xennia Technology Limited,
Royston, Hertfordshire, England

In 1996, Dr. Hudd co-founded Xennia Technology, the world’s first independent contract ink jet technology house dedicated to developing new ink jet inks for both the industrial and office ink jet industries.

In 1987, Alan joined Domino Printing Sciences and spent eight years as the Fluids Technology Manager, developing a wide range of ink jet ink for diverse applications and is credited with a number of patents and significant innovations within the industrial ink jet industry. Prior to Domino, he spent almost eight years with the Ministry of Defence and Royal Ordnance in the UK, developing new solid polymer rocket propellants for air to air missiles.

Dr. Hudd graduated with B.Sc. Honours degree in Chemistry and Physics, and M.Sc and Ph.D research degrees in Polymer Chemistry from Manchester University.
