CIELAB at 50: How We Got Here

This year marks the 50th anniversary of CIELAB, the colour space that has become the foundation of modern colour measurement, specification and quality control across multiple industries.

John is widely known throughout the colour and print industries as “John the Math Guy” and has spent decades helping organisations understand and apply colour measurement, as well as colour management principles.  

In this webinar, John will examine the key scientific developments, industry requirements and pivotal decisions that shaped CIELAB and continue to influence how we measure, communicate and control colour today.
