On art-tile inkjet lines, getting that glass-like glaze without a topcoat comes down to delivering UV energy the right way—no more, no less. Undercure leaves the surface tacky and ready to scuff. Overdo it, and pigments yellow and the substrate takes stress. So we run a room-integrated cure with a lamp built for this exact job, matched to the photoinitiator absorption of decorative UV inks on ceramic. What actually matters in the real world is spectral match and dose. We run a medium-pressure mercury vapor lamp, stabilized at 365 nm, with broad UVA output, hitting 800–1200 mW/cm² peak irradiance at the substrate plane. The reflector is dichroic-coated and elliptical, so it keeps the beam tight, wastes less IR, and holds reflector efficiency around 60–70%. It’s sized for 120–240 V, uses an ozone-free quartz envelope, and is rated for 3000 hours at full output. An integrated radiometer port lets you track dose in mJ/cm² and compensate as the lamp ages. And here is why it sticks. The 365 nm photons drive fast cross-linking of the acrylate oligomers in the ink, and the surface finishes like glaze—high gloss, pencil hardness above H, and solid chemical resistance. You get faster cycle times, fewer rejects from scuffing, and lower energy per tile because cure is instant at line speed. The lamp drops right into the UV offset/screen/hybrid printers used for ceramic decoration, with repeatable lamp-to-substrate distance setpoints. A couple shop-floor notes. Keep the working distance at 10–15 mm; stray outside that window and gloss and cure depth drift. The lamp needs a dedicated power supply and coolant loop, and ambient dust plus solvent vapors will shorten life. Before you validate the process, check spectral output with a spectroradiometer. Then run a dose matrix across print density to lock in the glaze finish without beating up the pigments.
