Reduction
SLOW: Dowanol
NORMAL: Meths
FAST: 1:2 Meths: Ethyl Acetate
With the use of any slow solvents, care should be taken to avoid solvent retention as even small percentages of “clean” solvents can cause taint and odour.
General
The main uses of water-based inks have been in the paper sack and carton field where highly absorbent papers or liners are used.
The system has been modified for less absorbent and more flexible substrates such as Polywoven Polyprop and Polyethylene.
The print becomes satisfactorily water resistant shortly after printing. The non-hazardous properties of the product are a major advantage.
