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.
