Mercury UV lamp for label printing

On a label press that never stops, the bottleneck is usually the curing, not the printheads. Under-cured ink migrates, adhesion falls apart, and die-cut dusting turns good rolls into scrap. Mercury UV lamps fix that by giving you stable, high-intensity output that’s aligned with the photoinitiator window in UV offset, flexo, and screen inks. What actually matters is spectral output and the energy density you deliver. Our medium-pressure mercury vapor lamps are built to hit strong output at 365 nm, with broadband emission on top to drive surface cure and through-cure through pigmented layers. Peak irradiance at the substrate hits 12 W/cm² at typical lamp-to-web distances, so you can land 400–800 mJ/cm² on thin films without cooking the web. The quartz arc tube and dichroic-coated reflector keep the spectrum stable, so cross-linking stays repeatable run after run. Output holds within ±5% over 2,000 hours, and lamp life is rated to 3,000 hours with a controlled end-of-life ramp. The payoff is speed you can control. You can push press speeds without chasing cure by dialing in lamp power; 120 W/cm lamps give you headroom for dense colors, metallics, and thick varnishes. Faster curing means quicker changeovers, fewer off-spec sheets, and the line keeps moving. Energy use drops because the reflector focuses UV onto the substrate, and ozone-free operation keeps the curing zone cleaner—less load on ventilation and cooling. Here are the details that matter on the floor. Lamp output is sensitive to arc gap, reflector alignment, and cooling airflow. Install to the specified distance and make sure airflow across the lamp face is consistent; otherwise, hot spots and uneven cure show up as banding. Before you swap lamps, confirm power supply compatibility—voltage, current, and igniter type—and match the spectral profile to the ink system. Run at the correct voltage and you stabilize color and adhesion, and you keep lamp end-of-life predictable.

Mercury UV lamp for offset printing

On the press floor, space never grows — but throughput demands always do. The question we keep hearing from offset printers is straightforward: how do you boost curing capacity by 30% without lengthening the cabinet or reworking the delivery? The answer is a modular, high-efficiency mercury UV lamp system built as a straight drop-in. What actually matters under the hood This module runs a high-pressure mercury vapor lamp with a spectral output tuned to peak at 365 nm, aligned to the absorption band of the photoinitiators in standard offset inks. You get peak irradiance of 12–15 W/cm² measured at the substrate plane, delivering curing energy density in the 800–1200 mJ/cm² range for typical ink films. A dichroic-coated quartz reflector focuses the output while keeping infrared load down, and the ozone-free design helps hold operating temperatures in line. Output stays stable over 3,000–5,000 hours, with spectral maintenance within ±5%. Why it fits the press as-is The module is built to plug in and run: same envelope dimensions, standard electrical termination, and fixed focal distance. In practice, you swap out the existing lamp without re-engineering the delivery section. Higher peak irradiance shortens the exposure window, so you can push press speed up by up to 30% while still getting full cross-linking and a proper surface cure. You end up with faster job changeovers, less risk of scumming, and consistent control of ink set-off — all without moving the curing station. What you need to double-check Because the spectral output and reflector geometry are matched, confirm arc length, lamp diameter, and mounting interface against your press model. Check power supply compatibility too — the module draws more current than the unit it replaces. Expect a short warm-up before output stabilizes, and schedule curing validation with a radiometer across the full width to confirm dose uniformity.

Mercury UV lamp for textile printing

We built these mercury UV lamps for one reason: to survive the brutal pace of textile printing. They’re tough, focused, and deliver that hard-hitting energy you need to instantly lock in inks and coatings—even when your line is flying. Here’s the inside scoop on what makes them work. We dialed in the power at 400V and 2500W because that’s what it takes to get the UV intensity you need for fast, reliable curing. It keeps the arc steady, and that power density gives you the punch across the whole substrate. And the 300mm length? That’s the sweet spot—designed to drop right into your existing curing station without a major overhaul. The body is made from high-purity quartz, so it handles the shock of rapid start-ups without blinking. We use a halogen fill gas to keep UV output steady over the life of the tube—no fading that leaves you with a half-baked cure. The R7s connector is straightforward and solid. It snaps in clean, transfers current reliably, and saves you from messy field wiring. On the shop floor, it’s a true drop-in replacement for standard curing modules. It keeps up with continuous cycling on PET and other synthetics, so your print line stays moving. But here’s the reality check: 2500W packs heat. Make sure your machine’s cooling system is up to the job. If it isn’t, you’ll risk overheating nearby components. Keep things cool, and this lamp keeps things running.
