Frequently Asked Questions

What is white UV ink used for in commercial printing?

White UV ink is used in commercial flexo and offset printing to provide opaque white coverage on clear films, foils, and coloured substrates. TWG-FXU-Ultra Opaque White is a specialist ultra-opaque white UV flexo ink used as a ground coat for full-colour packaging and label printing, delivering maximum white density for accurate colour reproduction.

What are the main advantages of using white UV ink in printing?

Ultra-opaque white UV inks like TWG-FXU-Ultra offer instant UV curing, maximum opacity for full coverage on challenging substrates, strong adhesion, and reliable print quality for commercial flexo applications. They eliminate the need for multiple white ink passes to achieve opacity, improving production efficiency.

Which printing machines are compatible with white UV ink?

White UV flexo inks like TWG-FXU-Ultra Opaque White are designed for use on UV-equipped flexographic printing presses. The press must be fitted with UV or LED UV curing lamps capable of delivering sufficient energy to fully cure the white ink. Contact Triwill Group’s technical team to confirm compatibility with your press configuration.

What is the curing process for white UV ink?

White UV inks cure through a photopolymerisation reaction initiated by UV light exposure. As the printed substrate passes under the UV lamp, the ink cures instantly to a hard, dry film. UV lamps must be correctly specified for the ink formulation and production speed to ensure complete cure of TWG-FXU-Ultra Opaque White.

What are the best practices for storing white UV ink?

White UV flexo inks should be stored in sealed containers away from direct light and UV exposure, at the temperature recommended on the product data sheet. Prolonged exposure to light or heat can degrade the ink and affect curing performance. Contact Triwill Group for specific storage guidance.
