PERSPECTIVES OF THE METAL PRINTING INDUSTRY
Guest presentation by Koenig & Bauer Metalprint: The presentation will explore single-pass and multi-pass metal printing approaches, highlighting the process requirements of both upstream and downstream operations, as well as the printing itself within the metal packaging market. The focus will be on the challenges of integrating digital printing into existing production lines and processes.
METAL PACKAGING TODAY AND TOMORROW: FOCUS ON SUSTAINABILITY
Guest presentation by Metal Packaging Europe: Metal packaging is under the spotlight as sustainability becomes a central focus across industries. This session explores the key trends and policies shaping both the present and future of metal packaging – from industry drivers and evolving European regulations to consumer preferences and recycling practices. It examines the expanding role of metal packaging in a context where sustainability and recyclability are at the forefront, offering a broad industry perspective on how these forces are influencing design, innovation, and manufacturing.

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.
