Course Focus

The Inkjet Academy has been attended by over 3,000 people in the past 18 years. Presented by Mike Willis of Pivotal Resources and Dr. Alan Hudd of Alchemie Technology, the course covers all the basics of inkjet technology.


Understanding the basics is essential to any industry’s development. The Inkjet Academy covers the basic theory behind the many types of inkjet technology used today and aims to give your understanding of the industry an expert start or update.


At the Inkjet Academy you’ll learn how printheads work, the materials used in their fabrication and the theory of their operation. You’ll also find out about how inks are formulated and used, as well as ink supply and support systems and much more.


The course assumes a basic scientific knowledge and is designed to provide useful background information for anyone entering the inkjet industry, seeking an update on today’s technology or looking for further fields of development.
