ABSTRACT:
A method and apparatus for laminating a protective overcoat carried on a web to an image carrying medium is particularly useful for covering an image carrying medium having a large area. A hot roller and an actively cooled cold roller form a nip through which the web and image carrying medium advance in a juxtaposed relationship. A temperature differential is created across the layers of the web and medium to promote adhesion between the surface of the protective overcoat and the image while preventing lamination artifacts such as curling and rippling. Postwrap and prewrap angles are used to enhance control of artifacts and assist in post lamination separation of the overcoated image carrying medium from residual web material.
