  • Good adhesion on paper, cardboard, OPP lamination film and a broad series of screen and offset inks.
  • Adhesion on other substrates should be tested prior to printing
  • These varnishes show good flexibility, when bended or folded
  • The varnishes are press-ready to print for screen
  • The varnishes are low in odour
  • The varnishes can be printed over offset inks
  • Quick and safe drying but the surface tension of the film or the substrate should at least be 38 dynes/cm

Depends on the type of varnish and on the type of application (effect to be achieved). In case of doubt, please contact our office.


The mesh should be cleaned with standard washing agent UV0009 or with our label free washing agent UV0002. Both are waterdilutable.


This varnish is formulated to cure under a dryer with one medium pressure mercury 120W/cm lamp at 30-40 metres/min. The better the UV drying, the better the adhesion on the substrate. 150mJoule is recommended. The curing depends on the kind of UV curing unit (reflectors, age and power of the UV lamps, the printed inklayer thickness and the belt speed of the UV curing unit). In certain cases the flow and the gloss can be improved by passing prints under IR lamps prior to UV curing.


The adhesion of the varnish is best evaluated after 24 hours. In this time interval, a post curing effect takes place during which the varnish cools down and the UV chemical termination reaction happens, resulting in a better adhesion.


UV varnishes is formulated free of heavy metals and complies with EN 71/3 standard.
These varnishes are REACH compliant and free from SVHC substances (Reach annex XIV) and substances mentioned on the candidate list (last update 16122014).
Please consult the MSDS.


When the UV varnish is stored between 15 and 20°C in its closed original can, shelf life will be minimum 12 months from date of manufacture. Varnish taken from the press should not be returned to the original container, but stored separately to avoid contamination of unused UV varnish.

  1. All surfaces must be free from grease, clean and dry before coating.
  2. As said, the surface to be printed should at least be 38 dynes/cm. Any tension lower than 38 will inevitable result in a poor or no adhesion. We strongly recommend that the surface tension be measured prior to printing in order to avoid claims from the end user of the printed product.
  3. The surface tension of the cured film with non gluable varnish is < 34 mN/m
  4. We also strongly recommend, before starting the varnishing, to check the print for bleeding resistance, as certain pigments in the inks tend to bleed when overlacquered with UV varnishes.
