TYPE OF INK - These types of inks are used to give a pearl effect over a dark background. This type of ink enhances the Print quality.

APPLICATION - On paper, board, rigid PVC, treated polyester.

THINNERS - Upto 20% UV thinners, uvv135 can be added.

DRYING - By exposure to UV high pressure mercury vapor lamps.

DRYING TIME - By using a two lamp machine at full power, belt speeds upto 25 metres per minute can be achieved.

ADHESION - Good to paper, board and screen printed material. Test proofs should be carried out when overprinting offset litho prints. Owing to the many various grades of plastic, substrates available test proofs should be carried out before proceeding with the actual print run.

MESH - Depends on the size of pearl between 110 T to 140 T.

COVERAGE - Between 45 square metres or 60 square metres depending on the mesh used.

STENCILS - Where direct emulsion systems are being used the number of coatings should be kept to a minimum. This will ensure that the thinnest stencil film is obtained, and this will give low ink deposits especially in fine detail areas. Where indirect stencil systems are to be employed use one of those now on the market which have been specially designed for UV printing.

CLEANING THE SCREEN - Screenwash should be used for washing up. As the inks have excellent screen stability, screens should only require washing up at the end of the run. Screens can be left overnight provided they are protected from direct sunlight and covered up to prevent dust contamination.

SHELF LIFE -Maximum of six months.
