The special feature of luminescent varnishes is that they are colourless and invisible in normal light. When illuminated with a UV lamp, however, they glow with bright, brilliant colours.
These invisible varnishes thus provide an ideal solution for product and copy protection, as well as various security solutions. In addition, it can also be a great design element, which gives much more room for creativity than traditional inks.

UVL Overprint Varnish series
Application Areas
The UVL series of Overprint Varnishes consist of a variety of varnishes for different application areas.
Generally, all of the varnishes are available in silicone-free and siliconed versions. The silicone-free varnishes are overprintable and also may allow printability with thermo transfer ribbons and foil stamping. The versions with added silicone exhibit better substrate wetting, higher gloss, higher resistance and enhanced slip properties, however they are not overprintable, thus recommended only for the top layer.
UVL002 Standard Overprint Varnish without Silicone
UVL003 Standard Overprint Varnish with Silicone
Standard series of a polyether acrylate based varnish, suitable for paper and plastic labels.
Recommended anilox roller: 6-12 cm3/m2 with 160-100 lines/cm.
UVL001 High Gloss Overprint Varnish without Silicone
UVL004 High Gloss Overprint Varnish with Silicone
Epoxy acrylate based varnish, exhibiting higher gloss compared to the standard series. Also suitable for paper and plastic labels.
Recommended anilox roller: 6-12 cm3/m2 with 160-100 lines/cm.
UVL024 Low Migration Overprint Varnish without Silicone
UVL029 Low Migration Overprint Varnish with Silicone
Low migration overprint varnish for indirect food packaging applications, formulated with high functional monomers and polymeric photoinitiators.
Suitable for printing the non-food contact side of paper and plastic packaging materials.
Recommended anilox roller: 6-12 cm3/m2 with 160-100 lines/cm.
UVL014 Release Varnish
UVL022 Low Migration Release Varnish
Standard and low migration/low odor version of a release varnish, with excellent release properties even for prolonged time, designed for making booklet labels.
Suitable for paper and plastic labels, especially for labels with hot melt adhesives (e.g. UPM Raflatac RH09).
Special care must be taken with paper labels with acrylic adhesive (e.g. UPM Raflatac RP37 or RP51), since these types of adhesives tend to migrate through the release layer. Prior printing tests and at least three weeks of waiting are necessary to see the suitability of the release varnish for such labels.
For paper and film labels high volume anilox roller is recommended: 10-14 cm3/m2 with 120-90 lines/cm.
UVL028 Low Migration Matte Overprint Varnish
Matte overprint varnish, suitable for paper and plastic labels, overprintable.
Recommended anilox roller: 10-12 cm3/m2 with 120-100 lines/cm.
UVL027 Texture Overprint Varnish with Paper Feel
Matte overprint varnish with coarse particles to provide a paper feel effect on plastic films.
Suitable anilox roller: 18-21 cm3/m2. An anilox with channel engraving is highly recommended, but a conventional closed cell anilox is also suitable as well. Anilox rollers with cell opening smaller than 50 microns are to be avoided, because the large particles may stick into the cells of the anilox roller.
The coarse particles tend to settle in the container over time, so strong mixing is necessary before printing.
Printing Properties
Pre-treatment: for plastic films, a corona pre-treatment of at least 38-44 mN/m is recommended.
Printing speed: up to 150 m/min (dependent on UV lamps and printing machine geometry).
Minimum recommended lamp power: 120 W/cm
Anilox selection: 6-12 cm3/m2 with 160-100 lines/cm
Prior tests are recommended to determine the optimal anilox volume for the desired properties.
Printing plate type: all printing plate types or rubber rollers developed for the usage of free radical curing UV inks can be used.
Cleaning: recommended cleaning solvents are methoxy propanol or ethoxy propanol, but any cleaning fluid for UV flexo inks could be suitable. Ethyl acetate is not recommended for cleaning the printing plates. Follow the advice of the printing plate manufacturer for suitable solvents.
The UVFCAT flexographic UV curing inks are specially designed for printing of polyamide sausage casings. They are 100 % cationic systems , ensuring good gloss, excellent adhesion, shirring and hot water resistance.
Area of use::
Outside printing of polyamide casings for food packaging, where the casing has to withstand shirring and cooking at elevated temperatures and pressure. Due to the variety of substrate materials, prior testing of printability and end use properties is recommended.
Print properties:
Printing speed: up to 100 m/min, dependent on UV lamps and printing machine geometry.
Minimum recommended lamp power: 160 W/cm, medium pressure mercury lamp.

Instructions for use
Maintain air humidity and temperature between the optimal points. Too high air humidity will decrease curing speed considerably.
Avoid cross contamination with radically curing UV inks, as well amines and basic materials. Processing additives with basic characteristics in the substrate can also negatively influence curing.
Cationic inks are touch safe and rub resistant immediately after irradiation with UV light, however the crosslinking process continues even in the absence of light and it reaches its final strength and adhesion after 24 hours. Shirring is recommended only after this period.

Metallic colours for printing labels and foils. In case of an absorbent substrate and thin layer thickness, a primer varnish or silicone free overprint varnish may be needed as a first layer to fill the pores of the substrate.
Print properties:
Note that overprinting metallic colours may be difficult, the next ink may need 0,2-0,5% wetting agent for a defect-free overprint.
