Abstract
The present invention includes preparing a carrier web with uniformly spaced images and corresponding registration marks at regular intervals, applying an energy curable resin coating to the carrier web either uniformly or in selected spots, providing a master web carrying uniformly spaced impressing images and corresponding registration marks at regular intervals where accurate alignment of the registration marks of the carrier web and the master web is achieved by stretching the master web to align the registration marks. The invention also comprises an apparatus including: (1) sensors which sense the location of the registration marks on the carrier web and the master web; (2) a computer programmed to monitor error signals representing the on-the-fly deviation in the alignment of the master and carrier web registration marks and makes determinations of the amount of stretching that must be applied to the master web in order to bring the registration marks into alignment; and (3) means for achieving the appropriate stretching of the master web to produce the desired alignment. In an alternative embodiment, a carrier web may also be prepared with a registered impressed image but a master drum will be used in lieu of the master web and the carrier web will be stretched as necessary to achieve image alignment.
