On the floor, printing metal and glass isn’t about looks. It’s about adhesion that holds under real conditions. When the UV lamp doesn’t deliver, the ink never fully cross-links, and the bond falls apart the moment you hit it with tape, solvent, or heat. You get rejects, rework, and stops. The answer isn’t laying on more ink—it’s delivering enough photon density, consistently. What actually matters With metal and glass, the cure is dictated by the photoinitiator absorption window and the need for deep cross-linking. Our high-intensity mercury vapor lamps put out a stable spectrum centered at 365 nm, with a broad H-line envelope that drives polymerization at the surface and deeper in. Peak irradiance hits 12 W/cm² at the arc midpoint, giving you cure energy density above 1,000 mJ/cm² in typical dwell windows. The reflector uses a dichroic coating to push output forward and cut wasted IR. We hold output stability within ±3% over lamp life, rated at 2,000 hours with less than 10% output decay. That stability matters because ink thickness and line speed are set; the lamp has to hold the dose. Why this works on the tough substrates High-gloss metals and low-surface-energy glass fight adhesion unless the ink cures fast and complete. The 365 nm output penetrates a bit deeper into the film, so you get a uniform cure profile from the top surface down to the substrate interface. The payoff is stronger molecular bonding and a harder film that survives cutting, forming, and handling. You can run thicker films without surface tack, shorten the curing zone, and still hit throughput. Over time, stable irradiance keeps the process window tight, which means less scrap and fewer recalibrations. A few shop-floor reminders These lamps are ozone-free, but they still need proper cooling. Keep airflow where it should be and keep the quartz envelope clean—even a thin film of dust will knock down delivered intensity. Match lamp length and arc gap to your reflector geometry and cure window. If you run very low press speeds, double-check that the dose doesn’t overshoot the ink’s cure window, and make sure your spectral radiometer and dose calculation method are compatible.
