TYPE OF INK - These inks have been developed so that a heavier film weight up to 0.5mm could be printed. Most of the printing is done for the blind people with this ink.

APPLICATION - On paper, board, PVC.

THINNERS - Up to 20% UV thinners uvv135 can be added.

DRYING - By exposure to UV high-pressure mercury vapour 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 - The correct deposit of varnish can be obtained through a mesh no finer than 10 - 25 T.

COVERAGE - Up to 4 and 10 square metres per litre is obtained using 10 T and 25 T mesh respectively.

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 - Screen wash 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 - Minimum of six months.
