You lay down thick ink, heavy <a href="https://o-yate.com">pigment</a>, 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.</p> <h2 id="what-actually-matters">What actually matters</h2> <p>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.</p>
