They’re picking and blocking as soon as you try to stack them. The first instinct is to blame the ink. More often than not, the real problem is staring you right in the face—your UV lamp has aged out, and the spectral output that used to drive full cross-linking has drifted. Tackiness is a curing failure, and curing failure is a radiometric failure. As the mercury vapor lamp ages, arc stability drops. The <a href="https://o-yate.com">quartz</a> sleeve loses transmission in the critical UV band, and the reflector’s dichroic coating degrades. The result is lower peak irradiance and lower delivered <a href="https://henruite.com">energy</a> density (mJ/cm²) at the substrate plane—even when the power supply still reads nominal.</p>
