Compatible with the main TTR printing technologies on the market, it is widely used in logistics, food, retail, and product traceability labels.

Application Methods

Flexography

DDGraf UV Flexographic Varnish is developed for application in narrow-web, modular, and center-drum flexographic printing presses, being the dominant finishing method in the production of self-adhesive labels, tags, and flexible packaging. Its low viscosity ensures uniform transfer through the anilox system, complete coverage, and faithful reproduction in solid and fine-screen areas.

UV technology allows for immediate curing under a lamp or LED system, enabling high-speed production without ventilation or drying time restrictions. DDGraf flexo varnishes offer excellent compatibility with BOPP, PET, PE films and treated papers, as well as suitable slip properties for folding, cutting and automated label application processes.

Calandra

DDGraf Calender UV Varnish is formulated for application in UV calender machines (manual and automatic) and in offset machines equipped with a dampening bath adapted for varnish. It is widely used in the finishing of covers, cards, cardboard and duplex cardboard packaging, where high gloss with a smooth, mirrored surface and high visual impact is desired.

The UV calender applies varnish in uniform, thick layers, and the instant UV curing generates a rigid film with high hardness and exceptional gloss. The DDGraf calender line covers viscosities from 30 to 100 seconds, allowing for fine adjustment according to machine speed and substrate type.

Offset

DDGraf UV Offset Varnish is developed for application via the inking system of offset printing presses, integrating into the production process without the need for a dedicated varnishing unit. With viscosities ranging from 200 to 900 seconds, the line covers everything from smaller machines to large-format offset presses, guaranteeing homogeneous application and uniform curing.

Available in versions for conventional paper and cardboard, for plastic substrates such as PVC, PS and Vinyl, as well as a matte version, the DDGraf offset line provides a finish with excellent adhesion, scratch resistance and compatibility with post-printing processes such as cutting, creasing, folding and gluing.

Screen printing

DDGraf UV Screen Printing Varnish is designed for use in automatic, semi-automatic, and manual screen printing machines, being the only method that allows precise control of the varnish layer thickness – simply by varying the thread count of the screen used. This opens up unique finishing possibilities, such as embossing, three-dimensional effects, and special applications like Scratch Off.
