Patent ID: 7857414

Claim:
A registration system for use with an imaging device, the system comprising: a first sensor configured to generate a first signal indicative of a speed a substantially continuous moving web, the moving web being configured to receive a marking material applied by at least two marking stations positioned along the moving web; a second sensor configured to generate a second signal indicative of a tension of the moving web; an image sensor configured to generate a third signal indicative of a relative position of a marking material applied to the moving web by at least two of the marking stations; a control system coupled to the first sensor, the second sensor and the image sensor, the control system being configured to generate a first timing offset for the at least one of the marking stations with reference to the first signal and the second signal, and to generate a second timing offset for the at least one of the marking stations with reference to the first, second, and third signals, the first timing offset and the second timing offset each being configured to advance or delay actuation of the at least one marking station to apply marking material to the moving web, the control system being configured to adjust an actuation time for the at least one marking station using the first timing offset and the second timing offset.
