The tendency for misting on offset printing inks was examined on two samples using the rotational rheometer Thermo Scientific HAAKE RheoStress 6000 and the extensional rheometer Thermo Scientific HAAKE CaBER 1.
The results for the amplitude and frequency curve, the creep and recovery test and the flow curve measurement with the rotational rheometer do not correlate with misting during printing.
With the rotational rheometer, it was possible with the aid of the filament break-up time to easily and quickly draw distinctions between different tendencies for misting with offset printing inks.
