Inkjet Academy
Theory of inkjet technology
17-18 September 2018
Novotel Barcelona City Hotel, Barcelona, Spain
INTRODUCTION
Knowledge of the technology behind any industry is essential to its development. The Inkjet Academy course 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.
The course will show you how printheads work, the materials used in their fabrication and the theory of their operation. You will also learn how inks are formulated and used, as well as about ink supply and support systems. The course examines how drops are formed, travel and behave on the substrate surface. Fundamental aspects of printer operation such as nozzle maintenance and print quality are also covered.
Presented by Mike Willis of Pivotal Resources and Dr Alan Hudd of Alchemie Technology, 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.
