Two Step Exposure – Combination of UV-A LEDs with UV-A tubes
In the first step a UV-A exposure is performed by scanning the plate surface with a high emission UV LED line. This results in a very fast crosslinking of the surface, even faster than the oxygen diffusion occurs. Thus, the oxygen effect is suppressed.
In a second step, the relief is created by exposure with standard UV-A tubes. In addition to a significantly higher level of UV intensity (up to 20 times), the emission of UV LEDs is much more consistent, and the lifetime is longer compared to conventional UV tubes.
Due to the beneficial characteristics of UV LEDs, which do not reduce their UV intensity over their lifetime in the way conventional UV tubes do, nylo- flex® NExT substantially enhances production consistency, especially for recurrence orders.
