Agenda and Content

Content of the Practical and Theoretical Blocks


Visualisation of inkjet printed drops: Demonstration and use of drop watching equipment in order to understand how ink drops are formed in the jetting process of a piezo printhead and how different parameters influence the formation of these drops.

Nano-dispersion quality: How can we check the quality and the stability of a nano-pigment dispersion? The UV-VIS technique for determining the degree of oversizers will be chosen as a show case.

Ink filtration: Demonstration of the cleanliness test, filtration based on differential pressure measurements and degassing of inkjet inks, its purpose and use criteria.

Adhesion: In this practical session the influence of the level of UV-curing, pre-treatment and the use of primers on the adhesion of UV-curable inks on several substrates will be tackled.

Inkjet printing: The printing of water-based inkjet inks and the determination of open time, wetting/penetration and print quality on different media depending on the printing parameters and the type of substrate.

Colour management: Aspects and Function of Linearization and Profiling, colour management in image rasterization, RIPs and colour spaces, the use of suitable measuring technologies.

Practical inkjet applications: Based on practical inkjet-printed objects we try to deduce the best combination of inkjet tools (head, ink, drying technique, etc.) that are necessary to produce such objects.

To all participants: If you have a personal lab coat and safety goggles, please bring them with you.


Situating inkjet technology: Where is inkjet used in the industry? What’s its evolution? The holistic approach for integration of inkjet technologies into industrial printing applications: ink/print head/media/process.

Inks for inkjet printing: Overview of the different inks that are currently used in inkjet printing, their characteristics and what makes them so unique for certain applications. What are important aspects to take into account when choosing or designing an inkjet ink?

Printheads: Overview of the different types of inkjet printheads (DOD, thermal, continuous…) and how to make a choice when using them in an industrial printing process.

The jetting process: We’ll further illuminate the ink-printhead interactions and all parameters that influence the jetting process of an ink by a piezo printhead.

Ink-media interactions: Can the spreading of the ink on a substrate be controlled? And what about the adhesion of inks on different substrates?

System Integration: How can we now integrate an inkjet printing process into an industrial production line? What are the important aspects to take into account? (size, speed, environment, robustness, cost, ink supply etc.)

UV-curing Filtration technologies: One part will explain UV-curing in printing, a comparison between conventional UV-lamps and LED-UV. The second part will handle the fundamentals of filtration techniques for assuring smooth printing inkjet inks.

Image quality: Challenges in combining coloured inks (CMYK and White) with specialty colours (Varnish, Extended Gamut, Spot, ...) in an inkjet printing system. How is colour matching achieved in 2D and direct to shape printing?
