Higher level of finishing for your labels

Flood varnish. Spot varnish. Cold foil. In-line with your finisher.

What is the UV varnish module for label finishing systems?


A retrofit flexographic unit that transforms your TAURUS or ARIES finisher into a premium label decoration system — in-line, no extra machine needed.


The UV varnish module is a full rotary flexographic unit equipped with an anilox cylinder and a Mercury UV lamp, designed as a retrofit accessory for D.P.R.’s TAURUS and ARIES label finishing systems. It applies UV varnish directly in-line during the label finishing workflow — adding protection, gloss or spot decoration without slowing down production.

Available in two configurations: flood varnish for complete surface UV protection, and spot varnish with cold foil capability for high-impact selective decoration including gold and metallic effects. An optional Vetaphone corona treater slot is available on both models.

Why add in-line UV varnish to your label finishing system

When finishing meets decoration — labels that protect, impress and sell more.

Flood Varnish — Total Protection

The full rotary flood varnish module (VRNx1x) covers the entire label surface with UV coating — delivering superior resistance to scratches, moisture and fading. An effective in-line alternative to traditional cold lamination.

Spot Varnish + Cold Foil

The spot varnish module (VRNx2x) applies UV varnish only to selected areas, creating contrast, tactile depth and visual impact. Includes cold foil capability for metallic, gold and holographic effects that make labels truly unmistakable.

Retrofit — No New Machine

Both modules are available as retrofit additions to existing TAURUS and ARIES systems, or factory-installed on new units. Easy to install and fully integrated in-line — no additional footprint, no extra operator.

Automatic UV Lamp Power Control

The UV lamp power adjusts automatically to match machine speed. When media stops, the protective shutter activates immediately — protecting both the label and the lamp, with a 1000-hour lamp warranty.

Optional Corona Treater

A Vetaphone corona treater slot is available on both modules. Treats the label surface before varnish application to improve adhesion on plastic films and specialty substrates. Available in 2kW and 4kW configurations.

Single-Color Printing Station

Alternatively, the flexographic unit can serve as a single-color printing station in-line with TAURUS or ARIES — adding print capability without a separate machine, expanding your production options further.

Q&A about the UV Varnish Modules

What is the UV varnish module for label finishing systems?+

The UV varnish module is a full rotary flexographic unit equipped with an anilox cylinder and a Mercury UV lamp, designed as a retrofit accessory for D.P.R.’s TAURUS and ARIES label finishing systems. It applies UV varnish in-line during the label finishing workflow, adding protection and premium visual impact without an additional machine.

What is the difference between flood varnish and spot varnish?+

Flood varnish (Type 1, model VRNx1x) covers the entire label surface with a uniform UV coating, providing superior protection against scratches, moisture and fading with a consistent gloss or semi-gloss finish. Spot varnish (Type 2, model VRNx2x) applies varnish only to selected areas, creating visual contrast and tactile depth. The spot varnish module also includes cold foil capability for metallic and gold effects.

Which label finishing systems are compatible with the varnish modules?+

Model VRNT (flood varnish) is the retrofit module designed for TAURUS laser label finishing systems. Model VRNA (spot varnish with cold foil) is the retrofit module designed for ARIES semi-rotary label finishing machines. Both are also available factory-installed on new TAURUS and ARIES units.

What is cold foil and how does it work on labels?+

Cold foil applies metallic or holographic foil to selected label areas using UV adhesive, without the heat required by hot stamping. The VRNA spot varnish module includes cold foil capability, allowing converters to add gold, silver or custom foil effects in-line with ARIES — turning standard labels into high-impact premium products at production speed.

What is the corona treater option and when is it needed?+

An optional Vetaphone corona treater can be installed alongside the varnish module to treat the label surface before varnish application, improving adhesion on plastic films and challenging substrates. Two power options are available: 2kW (iPM100 + VE1A-M-410 treater station) and 4kW (iPM200 + VE1A-M-410). It is particularly recommended when working with PP, PET or other non-porous films.

What are the technical specifications of the UV varnish module?+

Media type: paper and plastic films. Installed lamp: Mercury UV (UV Ray model, from 160W). Lamp warranty: 1000 hours. Power supply: 400 VAC three-phase, 50/60 Hz. Total absorption: 7kW. Compressed air: 6 Bar. UV lamp power adjusts automatically to machine speed, and a protective shutter activates immediately when media stops.

Can the varnish module serve as a printing station?+

Yes. The flexographic unit in both varnish modules can alternatively serve as a single-color printing station in-line with TAURUS or ARIES, providing additional print capability without requiring a separate machine.

Why invest in in-house varnish finishing?+

Adding in-house varnish finishing eliminates outsourcing for premium label decoration, reducing lead times and costs. It gives converters full control over quality and turnaround, enables same-day premium finishing, and creates new revenue opportunities by offering flood varnish, spot varnish and cold foil as value-added services to their own customers.

Turn every Label into a Premium product
In-House, In-Line, In One Pass.


Your customers judge your brand by the label on the product.
A gloss UV coating catches the light.
A spot varnish accent draws the eye.
A cold foil gold effect signals luxury before the product is even touched.

Until now, achieving this level of finishing meant sending rolls out to specialist converters — adding cost, lead time and quality risk. The D.P.R. varnish modules bring all of that in-house, in-line, with no extra machine and no extra operator.

The result:
Premium label decoration in-house, Same-day turnaround, Lower outsourcing cost, New revenue from value-added finishing, Labels that sell more
