If the UV cure doesn’t go deep enough, pigments lift and the image starts to fade. So the real question is practical: how many years of color stability can you actually get from a UV-cured print?</p> <h2 id="power-spectrum-and-cure-depth">Power, spectrum, and cure depth</h2> <p>Uvitron UV curing lamps are built around high-pressure mercury vapor lamps, tuned for repeatable spectral output. The <a href="https://o-yate.com">dominant</a> lines at 365 nm and 366 nm are what drive deep cross-linking in acrylate-based UV inks and coatings. Peak irradiance at the substrate plane hits 1.2–1.8 W/cm², putting 600–1200 mJ/cm² down in a single pass on typical canvas profiles. That kind of energy density exhausts the photoinitiators through the full ink layer, not just at the surface. The reflectors use high-purity anodized aluminum with a dichroic coating, biasing output toward the short-wave UV that pigment-loaded formulations need. Output stays stable over 2000 hours, with less than 8% drop in irradiance when you stay within the rated operating envelope.</p>
