Agenda and Content

CONTENT OF THEORY BLOCKS

Piezo - Inkjet: Overlooks the fundamentals of inkjet print head technology, their geometry, functionality and the variety of physical structures, as much as their drive parameters and key influencing factors for the inkjet printing processes.

Inks and SubstratesHighlighting the different ink types such as UV Curing, Solvent-, Eco Solvent- and water based, their Raw Materials, Rheology, Drying, Wetting, Dot Gain, Adhesion, Pre-Treatment and Color Management. A special focus is put on the formulation of inkjet inks, their manufacturing processes for use in jetting applications. How to achieve optimal adhesion of printed inks onto different substrates and which roll raw materials, surface tensions of the ink and the substrate play and how printed results can be optimized by the use of specific primers or pre-treament processes.

Printing Equipment / Hardware of inkjetbased printers: An industiral printer consists of more than just single printheads. Mechanics, fluidics and electronics must be optimally designed and precisely matched to the application. In this theoretical part, the basic requirements of an industrial printer are illustrated and the necessary functional groups and their interaction are demonstrated. In addition, the control of the printheads is shown.

Piezo Technology and its Limits: Piezo inkjet and further industrial inkjet printing technologies of different manufacturers, their design, advantages and disadvantages are discussed, as well as their physical limitations.

Colour Management: Quality assurance strategies in production printing, colour measurement, RIP systems and extended gamuts.

Inkjet 1-on-1: Special breakout sessions to answer your individual questions


CONTENT OF PRACTICAL BLOCKS

Ink Characterisation: Examine viscosity curves in relation to temperature, surface tension, material compatibility, cleaning agents.
Determination of Print Parameters: Parameters such as meniscus vacuum, waveform, drop spacing, tool life and resolution.
Drying Mechanisms and Cleaning of Printing Units: Drying with UV LED, UV HG and heating table; cleaning process when changing the liquid.
Print Unit Engineering and Process Peripherals: Mechanics, fluidics and electronics.
Key Factors of Influence on Print Quality: Quality changes implied by the substrate, pretreatment and printing speed.
Evaluation of Print Quality: Print quality analysis depending on e.g. wetting, edge sharpness, curing, homogenity and many more.
Colour Management: Ink deposition management, colour management in image rasterisation, RIPs and colour spaces, use of suitable measurement technology.

For whom

The ESMA Academy is targeted towards companies who:
• want to obtain a well-founded overview on digital printing technologies, especially on piezo inkjet, in order to make an educated decision to what extend inkjet technologies could be integrated into their production process.
• want to obtain basic inkjet know-how in order to plan a possible introduction of inkjet technologies into their organisation and facilitate their investment decisions.
• are planning to start with inkjet or have already installed inkjet equipment in their organisation but are still at the very beginning of the learning process.

Speakers

Jochen Christiaens, Zeller Gmelin
• Prof. Dr. Stefan Güttler, Hochschule der Medien
Jan Janhsen, Fraunhofer IPA
Oliver Kammann, K-Flow Consulting


ESMA Certificate

Participants will receive a certificate after attending all theoretical and practical sessions.
