The focus of the course is to train participants in assessing, developing and improving waveforms for a drop on demand inkjet printheads as well as to be familiar with measures for reliable printhead operation. Hands-on practical lab work is supported by short theoretical lessons.
This course covers all aspects of rheology relevant to inkjet printing and at timescales relevant to inkjet printing. We discuss shear (low, mid and high), high frequency, and extensional rheology. We also look at the influence of ink components on ink rheology and its influence on the jetting behavior. We explore ways to optimise inks rheological properties to control misting, satellites, and achieve reliable jetting.
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. The course is open to everybody in inkjet that wishes to broaden their knowledge base.
