IMI Europe Inkjet Winter Workshop

Inkjet Printing Software – PRINTHEADS, IMAGES & COLOUR

Wednesday 24 – Thursday 25 January 2018, Ayre Hotel Astoria Palace, Valencia, Spain

For any digital imaging technology, software is fundamental as the printed image is defined by data, rather than by a physical object like a roller or screen. Inkjet printing software accepts design image files as its input and needs to transform this into data understood by the printheads as an instruction either to fire, or not to fire, a nozzle actuator at a given time. This complex task requires image handling and colour management to ensure consistent colour, especially for advanced decorative applications. The printing software also needs to split the data into suitable channels directed to each printhead in the system. It also needs to handle extremely high data rates to drive today’s high resolution, high speed printheads, especially in single pass printing applications with multiple colours and large image sizes.

IMI Europe’s Inkjet Printing Software course gives an in-depth overview of the fundamental aspects of digital imaging applications and the software functions needed for this, presented by leading companies in the field.

Thursday 25 January 2018

Software for decorative applications
Kerry Port, AVA CADCAM

  • What to consider when preparing a file for digital print:
    • Editing, designing and repeating
    • Layer separations – channel workflows, why separate for digital? Colour control or colour variations?
    • What are the benefits over an image manipulation workflow when you’re colour critical?
    • Linearisation, profiling and soft proofing – checking and rechecking your colour match.
    • Printing – through AVA or third party RIPS.
    • Managing your digital print- how to monitor the variables.
    • Image handling and colour management.
    • Why image & non-specialised workflows are not ideal for high-end decorative printing.
