Agenda and Content

Content Practical and Theoretical Blocks

PRACTICAL BLOCKS

Ink characterisationExamine viscosity curves in relation to temperature, surface tension, material compatibility, cleaning agents

Determination of rheology and viscosity curves in function of temperature variation, as well as surface tension as basic parameters for printing. Checking the compatibility of ink and cleaning agent with the components of the print heads. Good compatibility ensures the longevity of the printing system and high system productivity and efficiency..

Determination of Print ParametersParameters such as meniscus vacuum, waveform, drop spacing, tool life and resolution

Drying mechanisms and cleaning of printing unitsDrying with UV LED, UV HG and heating table; Cleaning process when changing the liquid

Print Unit Engineering and Process PeripheralsMechanics, fluidic and electronics

Key Factors of Influence on Print QualityQuality changes implied by the substrate, pretreatment and printing speed

Evaluation of Print QualityPrint quality analysis depending on e.g. wetting, edge sharpness, curing, homogeneity, and many more.

Color ManagementInk deposition management, color management in image rasterization, RIPs and color spaces, use of suitable measurement technology


THEORETICAL 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 EquipmentMechanics, Fluidics, Electronics, Datapath, Raster Image Processor and single color print bars (Extended Gamut Printing)

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.

Closing Session, evaluation and certificates

For whom

The ESMA Academy is targeted towards European 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, Inkjet Consulting Christiaens
• Jessica Günthel, Fraunhofer IPA
• Prof. Dr. Stefan Güttler, Hochschule der Medien
• Oliver Kammann, K-Flow Consulting
• Oliver Refle, Fraunhofer IPA


ESMA Certificate

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

The maximum number of participants is limited to 17-21 due to the number of laboratory stations and rooms (max. three participants per station)

Organised by ESMA

ESMA is the knowledge platform for industrial, functional and specialist printing technologies.
