Inkjet Academy
The Theory of Inkjet Technology
28-29 November, 2016
Novotel Amsterdam City Hotel, Amsterdam, Netherlands
Introduction
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 will learn how printheads work, the materials used in their fabrication and the theory of their operation. You’ll also find out about inks used for industrial printing, and how they are formulated and used. Ink supply and support systems and integration issues are also covered.
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.
