  • Patent number: 8316764
    Abstract: An apparatus and method for preparing a sheeted substrate with a registered structured image in which a resin coated sheeted substrate is provided in the form of a series of spaced sheets with leading or trailing edges acting as reference positions along with a master web with structured images and registration marks. Reference positions of the series of spaced sheets are aligned with the registration mark on the master web and the master web is nipped to the coated sheeted substrate after which curing energy is applied through the master web to the resin coat while the master web and sheeted substrate are in contact. Then the master web is separated from the sheeted substrate to leave a structured image on the sheeted substrate. Registration between the sheeted substrate and the master web may be maintained by varying the relative speed of the master web and the sheeted substrate through stretching of the master web.
