| TYPE
OF INK - Water based Screen ink. |
| APPLICATION
- On paper and board. |
| THINNERS
- Small amounts of tap water can be added when required. |
| DRYING
- By exposure to atmosphere in racks (about 30 minutes)
or by exposure to warm jet air. In some
dryers cold air may be sufficient. |
| ADHESION
- Good on paper and board. |
|
MESH
- The correct deposit of varnish can be obtained using
mesh size form 90T to 140T.
|
| COVERAGE
- Upto 40 square metres/litre can be obtained with 90T
mesh. Upto 50 square metres/litre can be obtained with 120T
mesh. |
| STENCILS
- Water resistant stencils are essential. Direct emulsions
or capillary type films give the best results. |
|
CLEANING
THE SCREEN - Wash up with water immediately after use.
If screens are left with dried ink a special detergent blend
can be used to soften the ink, prior to pressure washing.

SHELF
LIFE - Indefinitely in tightly closed containers. Do
not store below 50. Ink which has become frozen
can not be recovered. Ensure inks are resealed immediately
after use. If the ink is exposed to the air for several hours
a water insoluble skin may form. This must be carefully removed
before use. If left in the ink, or an attempt is made to mix
the skin into the ink, you will end up with undispersed material
which renders the ink useless.
