This 1 liter bottle offers a UV‐curable varnish (clear coat) version of the Q4 series, ideal for digital flatbed or hybrid UV printers.

The product leverages the same Q4 UV ink base technology but formulated for protective, decorative finishing rather than pure colour output.

UV-curable formulation: Cures instantly under UV or LED UV lamps, yielding a fully polymerised surface that is ready for handling, finishing, or post-processing with minimal downtime.
High compatibility: Designed for use on a variety of rigid and specialty substrates commonly used in signage, displays, point-of-sale, retail graphics, and decorative applications (e.g., boards, glass, acrylic, metal). (While the standard Q4 UV ink version supports a broad substrate range. sunbeltsign.net+1)
Durability & finish: Provides enhanced scratch, abrasion and weather resistance compared to conventional inks. The varnish layer improves aesthetics (gloss or satin effect depending on curing conditions) and protection (against scuffing, handling, outdoor exposure).
High production stability: Formulated for large‐format, high‐resolution digital printing environments, with good jetting stability, long print runs and reduced maintenance requirements. sunbeltsign.net
1 L size: Convenient for production use, giving adequate volume for medium to large print jobs without frequent bottle changes — helps maintain workflow continuity.
