In this presentation, we explain how basic principles of UV measurement provide the foundation required to properly measure and monitor narrow-bandwidth UV LED sources used for today's graphic arts.  Using field data, we demonstrate that applying the same tools and techniques for LED used with broadband mercury-based light sources can produce errors, poor-quality, inadequate ink cure, and loss of process control.  Therefore, conversion to LEDs from broadband sources requires planning and a change in measurement protocol. Several practical suggestions for avoiding common pitfalls of LED measurement in printing applications are provided.
