Abstract: The invention relates to a curing unit for use integrally with, or attached to, further apparatus for the provision of for example, a photo reactive thermal laminator which allows the lamination of a substrate, typically in the form of a sheet material. In use the apparatus includes at least one curing lamp which emits UV light and through which the substrate with a transfer film placed thereon passes. The emitted light serves to cure the coating material of the transfer film and hence laminates the substrate. Protection is also claimed for the lamp configurations used.
