On UV offset, flexo, and screen lines, the lamp isn’t just a heat source—it’s a photochemical reactor. If you don’t have verified spectral output and irradiance, you’re not actually controlling cross-linking.</p> <h3 id="what-matters-technically">What matters, technically</h3> <p>When you test lamps, your UV intensity meter has to see the emission peaks that actually drive photoinitiator response. With high-pressure mercury vapor lamps, that’s primarily 365 nm. LED-UV and hybrid systems are pushing more 385 nm and 405 nm. You need a calibrated radiometer with traceable units, reporting peak irradiance in mW/cm² and <a href="https://henruite.com">cumulative</a> energy density in mJ/cm² over a defined exposure area. And the measurement geometry has to match the curing window: distance, beam profile, and reflector efficiency all change the dose that lands on the ink. Repeatability beats a single flashy reading. The meter should stay stable across lamp warm-up, track output decay over lamp life, and expose reflector degradation by comparing current intensity against the baseline you set when everything was new.</p>
