On a high-speed garment line, the cure step is where throughput falls apart. If the lamps can’t keep up, the ink stays wet, transfers smear, and you’re stopping the line to recoat or scrap. Second-level curing isn’t a buzzword—it’s the hard line between a profitable run and a bunch of idle machines. That line is measured in photons, not hope.

What actually matters

Gallium iodide lamps push the spectral output toward 385–405 nm, which lines up with the photoinitiators in a lot of UV inks and cuts down on the short-wave energy that adds heat. We spec a peak irradiance of 12–15 W/cm² at the substrate plane, and a curing energy density of 300–600 mJ/cm² in a single pass. The dichroic reflector focuses the output into a tight band, so you get more photon flux per joule and less thermal load on the substrate. Ozone-free operation comes from quartz with a controlled oxygen-blocking coating, which keeps the lamp head cooler and helps you avoid maintenance interruptions.
