​​​​​​​​​Hands-on Lab Course
lnkjet Engineering and lnkjet Chemistry
Foundation Course 

 

1. COURSE OBJECTIVES


The objectives of this foundation course in inkjet engineering and inkjet chemistry are to broaden the knowledge base and to acquire inkjet specific terminology and vocabulary enabling interdisciplinary communication and discussion between the disciplines.
The theory sessions are backed up by hands-on lob training. Participants mesure the physical properties and introduce the concepts of material compatibility, pigment dispersions stability and waveform development.

 

2. PARTICIPANT PROFILE


The course is open to everybody in inkjet that wishes to broaden their knowledge base:
No motter if you are an expert in a specific field of inkjet who wishes to better understand oth­er disciplines, if you are involved in inkjet system integration or in inkjet system operation or if you are a newcomer to inkjet.


3. ENTRY REQUIREMENT


Either qualification and experience in one of the following areas:

- Mechanics
- Electronics
- Chemical Engineering
- Chemistry
- Color Science
- Experience in development of printing systems or ink
