The testing ink 38 dynes was developed in order to control the successful pre-treatment of plastics for further processing [ e.g. printing, lacquering etc. ]. The testing ink can be used for the visualization of the pre-treatment using corona, plasma, primer as well as flame treatment. A successful pre-treatment can immediately be observed as a continuously closed film. In case of a beading effect pre-treatment was not successful and corrective measures need to be taken.
