Why Choose Starcolor Traditional UV 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

Frequently Asked Questions

Q: Is Traditional UV Ink compatible with LED UV curing?

A: No. This product is engineered for mercury-lamp UV curing systems and is not suitable for LED UV wavelengths.

Q: Which printing methods is this ink suitable for?

A: Optimized for flexographic printing. Consult us for retrofits or specialty press configurations.

Q: Can I order custom Pantone or spot colors?

A: Yes — we offer spot color matching and custom formulations. Lead time and MOQ apply.

Q: What safety certifications or compliance does it meet?

A: The formulation is free of heavy metal pigments and restricted solvents. For food-contact or regulatory statements, request specific compliance documentation.

Q: What sample sizes are available?

A: Trial samples (250–500 mL) and production-size drums are available. Contact sales for logistics and pricing.
