Why Choose Starcolor UV Mercury-Cure Ink

Starcolor's UV Mercury-Cure formulation is engineered for reliable curing performance on traditional mercury-lamp systems — including lower-energy or aged lamps. Compared with many standard UV inks, it offers improved adhesion on coated and film substrates, more consistent runnability on long production runs, and lower migration risk for surface-printed packaging.

Recommended Curing & Press Guidelines

Mercury lamp energy: 120–160 mJ/cm²
Best printing speed: 100–220 m/min (test per press)
Maintain lamp cleanliness and reflector condition for consistent cure
Substrate surface tension: recommended ≥ 38–42 dyn
