Abstract: The present invention relates generally to an apparatus for embossing a flexible substrate. More specifically, the present invention relates to an apparatus for embossing a curable composition coated flexible substrate with an optically variable image transferred from an embossing foil, especially belt, or sheet of an optically transparent fluoropolymer. The optically variable image is irradiated through the embossing belt, or sheet with ultraviolet light contemporaneously with the embossing so that the transferred imprint pattern cures, hardens, and retains its shape.
