Often the culprit is right in front of you: a thin film of oil and smoke residue on the UV lamp and reflector. It blocks the spectral output, cuts peak irradiance, and leaves photoinitiators unreacted.</p> <h2 id="what-matters-technically">What Matters Technically</h2> <p>A UV coating curing machine lamp is measured by delivered energy, not just wattage. We specify stable output at the key wavelengths your ink or coating chemistry depends on—365nm for deep through-cure, 385–405nm for surface cure and faster cycles. Peak irradiance, measured in mW/cm² at the substrate plane, <a href="https://goldisgood.com">determines</a> whether you get instant cross-linking or a slow, incomplete reaction. The reflector’s dichroic coating is <a href="https://o-yate.net">engineered</a> to direct the right band back onto the web, and even a light haze on the lamp envelope scatters and absorbs photons, lowering the mJ/cm² that reaches the print.</p>
