Frequently Asked Questions

What is UV ink duct coating?

UV ink duct coating is a UV gloss coating formulated to be applied through the ink duct (inking unit) of an offset press, rather than a dedicated coating unit. This allows inline UV gloss finishing using a printing unit, cured instantly under UV light.

Why apply UV coating through the ink duct?

Applying UV coating through the ink duct lets printers add gloss finishing without a dedicated coating unit, using an available printing unit. This is useful for spot gloss effects or where a coating tower is not available.

Can TWGU6400 be applied as a spot coating?

Yes. TWGU6400 can be applied as spot gloss (selected areas) using a printing plate, or as a full flood coating, depending on the finishing effect required.

Does TWGU6400 require UV curing?

Yes. TWGU6400 is UV-curable and requires a UV curing system on the press. Contact TriWill Group to confirm compatibility.
