Acoustic investigation of cavitation noise from offset ink film splitting

Voltaire, Joakim; Fogden, A; Craig, Vincent; Jansson, Daniel; Jacobsson, Niclas


The acoustic signal from the nip during film splitting between inked rollers and on ink transfer to paper was investigated on laboratory scale, using two sheet-fed offset inks (based on mineral oil and vegetable oil) and two coated fine papers (glossy and matte). Film splitting emits a broad noise-like acoustic spectrum in the range 5-50 kHz, from which the two simplest measures of average power and average frequency were derived. Using these two measures, four characteristic regimes of film...[Show more]
