When the lamp underperforms, you don’t just lose time—you lose yield. You start seeing tack, adhesion failure, rejects that should never have left the line. And the root cause is rarely as simple as “the lamp is dead.” More often, it’s spectral mismatch, dropping irradiance, and a reflector that isn’t delivering the energy density it was designed to at the cure plane. A mercury vapor lamp isn’t just a heat source. It’s a photochemical driver. UV ink cures because photoinitiators inside the ink absorb specific wavelengths, then generate free radicals that force monomers and oligomers to cross-link. If the output at the key wavelengths is too low, the reaction stalls. If the output profile drifts, you can get a surface that looks cured while the bulk stays undercured.</p>
