UV curing lamp for credit card

On the credit card line, downtime isn’t a choice—it’s a production killer. When a lamp goes down, you lose curing energy fast, and the card substrate or those overprinted security features just don’t cross-link properly. What you need is a UV lamp that drops in, fires up, and performs—no rewiring, no guesswork, and no compromise on cure depth.

What matters under the hood

Credit card inks and coatings are tuned around specific photoinitiators, so spectral output isn’t negotiable. We run high-pressure mercury vapor lamps with stable peak irradiance at 365 nm for deep through-cure, and enough output across 385–405 nm to finish the surface cure without cooking the PVC/PET core. Reflectors use dichroic coatings to shape the spectrum and keep heat away from the substrate. We measure output at the web: target energy density of 600–800 mJ/cm², with peak irradiance that keeps pace with high line speeds. Lamp life comes from controlled electrode design and quartz envelope stability—we’ve got units that run 5,000+ hours with less than 5% output drop.
