A sensor has a transmitter portion and a receiver portion, the receiver portion comprising a plurality of receivers, the transmitter portion and receiver portion are configured to receive a portion of the label stock therebetween, and the plurality of receivers are each configured to produce a respective sensor signal which is a function of a property of a portion of label stock at a plurality of positions spaced from one another in a direction non-parallel to the web path. In addition, a controller is configured to monitor each of the sensor signals produced by the receivers and to select one of the sensor signals produced by the receivers based on said monitoring of each of the sensor signals produced by the receivers.
