On the press, thick-build jobs blow up when the top surface cures before the bottom. The ink skins over, trapping solvents and uncured photoinitiator. You know what follows: adhesion loss, cracking, and whole runs that come off the stack as scrap.

What actually matters

Thick-build ink cures through photopolymer cross-linking, and that comes down to delivered UV energy density (mJ/cm²), not the “lamp power” someone wrote on a spec sheet. Peak irradiance at the substrate controls how fast you hit the ink’s dose threshold, while spectral output controls how deep that dose penetrates. High-pressure mercury vapor lamps put out strong 365nm, and that wavelength punches deeper through pigmented and filled systems than shorter wavelengths do. When the photoinitiator absorption band lines up with the lamp spectrum, the cure front moves from the bottom up. Pair that with a dichroic reflector to focus the output and a stable arc to keep spectral distribution consistent, and you can hold a repeatable dose through the full layer thickness.
