Inkjet Academy

27-28 January, 2016

Keio Plaza Hotel, Tokyo, Japan


Basic knowledge of any industry is essential to its development. The Inkjet Academy covers the basic theory behind the many types of industrial inkjet technology used today and aims to give your understanding of the industry an expert start.

On the course you’ll learn how printheads work, what materials are used in their fabrication and the theory of their operation. You’ll also find out about inks used for industrial printing, how they are formulated and used and about ink supply and support systems.

The course is designed for those with a basic scientific knowledge and will provide useful background information for anyone entering the industrial inkjet industry, seeking an update on today’s technology or looking for further fields of development. The teaching presentations will be in English but the course materials will be printed in both English and Japanese.
