UV1000 Screen

Properties

  • 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

Recommended Mesh 

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

Cleaning the Mesh

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

Shelflife & Storage

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.

Drying

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.

Post Curling

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.
