Use of an on-press acoustic sensor to monitor coldset offset printing of newspaper

Voltaire, Joakim; Fogden, Andrew; Hoc, Miroslav


A newly developed acoustic emission on-line monitoring technique (Voltaire J. et al. 2004) provides insight into the dynamic interactions occurring between paper, inkfount emulsion, and rubber blanket in offset printing. The technique uses a microphone placed in the vicinity of the exit of the paper-blanket nip. Through digital signal processing of the measured sound pressure it is possible to distinguish between machinery sound and that caused by the tacky ink splitting. In this study,...[Show more]
