INK ADDITIVES

GRAFO DRIER EXTRA
GRAFO DRIER EXTRA (GDX) is a drier with unique properties. It is water reactive and when adding 2 to 3 % to the ink, the emulsified water triggers off a chemical reaction, liberating an extra amount of oxygen which balances the negative influence of emulsified fountain solution.

GRAFO GEL
GRAFO GEL is a paste for reducing the tackiness of both offset and letterpress printing inks. In comparison with conventional ink reducers such as linseed or mineral oil, GRAFO GEL scarcely changes the viscosity of the ink even when an addition of up to 10% is used. Colours will not weaken and the flow of the ink will not be diminished. Other properties of the ink, like drying and density will not be affected. Besides, GRAFO GEL helps also as an anti-set-off gel.
