UV lamp for screen printing

On the floor, screen printing comes down to one thing: curing. You lay down thick ink, heavy pigment, and hold tight registration. When the lamp can’t keep up, the line stalls—tacky jobs, pinholes, adhesion that fails and scraps the run. We built this UV lamp for screen work to stop that from happening, with spectral output you can count on and energy density that stays steady, shift after shift.

What actually matters

We spec high-pressure mercury vapor lamps with a matched spectral profile—centered at 365 nm, and strong output around 313 nm and 436 nm. That’s how the photoinitiators in thick-layer inks cross-link all the way through the deposit, not just at the surface. Peak irradiance is engineered to top 1,200 mW/cm² at the substrate plane, delivering curing energy density in the 800–1,200 mJ/cm² range for typical screen inks at production speeds. The reflector uses a high-reflectivity dichroic coating to shape the beam and cut wasted IR. That keeps substrate temperature under control and improves electrical-to-UV conversion efficiency. Output stays stable for 1,000+ hours, and with routine maintenance you keep lamp-end intensity inside a tight window.

We built this mercury UV lamp for the high-pressure work of catching counterfeits. Here’s the headache it solves: security inks only wake up under a very specific kind of light. Most UV lamps are too broad, and they wash the details out. Ours is built for pure, targeted wavelength output, so the security mark pops—bright, sharp, and unmistakable. Forgery attempts don’t stand a chance. Power and precision, in practice At the heart is a high-intensity mercury discharge, tuned to deliver a stable, high-output beam at exactly the wavelengths those inks need. It’s powerful enough to trigger the ink the instant the textile moves past—no delay, no smearing—even at high line speeds. And the electrical design stays rock-solid on voltage, so there’s no flicker to wreck print consistency. Built to survive the press room The lamp body is high-purity quartz glass. It handles the thermal shock of rapid on/off cycles and lets the short-wavelength UV through cleanly. Inside, we use a precise coating to strip away the unwanted wavelengths, leaving only the pure output needed for the ink reaction. And it plugs in with an R7s base—an industrial-grade fit that makes it a direct drop-in replacement for most press-side fixtures. It carries the high current safely, so the contacts stay cool. Designed for real-world textile printing This lamp lives inside the press. It has to take the pounding and keep running. So we focused the UV energy into a tight footprint, which cuts down wasted energy and keeps excess heat off the substrate. That keeps the machine’s cooling system from getting overwhelmed. Just one note: that concentrated power creates real thermal density. Make sure the lamp housing and the machine ventilation are up to the job. Keep it properly cooled, and the quartz stays stable—so the lamp holds its spectral output for the long haul.
