A method of laminating a pre-press proof () is disclosed comprising the steps of treating a sheet of plastic material () with a corona discharge. Laminating a pre-laminate sheet () comprising a first thermoplastic layer () and a first support layer () to the sheet of corona discharged treated plastic material (). Removing the first support layer () to form a pre-laminated receiver stock (). Creating an imaged receiver sheet () with a second support layer (). Laminating the imaged receiver sheet () to the pre-laminated receiver stock () thereby encapsulating the image. Removing the second support layer () thereby forming the pre-press proof ().

Method of preparing plastic materials to allow lamination of a pre-press color proof

A method, a laminator ( ), and a belt, for creating a pre-press proof ( ) with a thermal mark ( ) which comprises laminating a pre-laminate sheet ( ) consisting of a first thermoplastic layer, and a first support layer ( ) to a receiver stock ( ); removing the first support layer ( ) forming a pre-laminated receiver stock ( ); creating an imaged receiver sheet ( ) with a second print layer ( ) and a second support layer ( ); laminating the imaged receiver sheet ( ) with the pre-laminated receiver stock ( ) using an embossing belt ( ) with an embossing mark and removing the second support layer ( ) creating a pre-press proof with a thermal mark ( ).

Lamination method to create a pre-press proof with a thermal mark

The present invention involves a method for forming an improved lamination envelope ( ) for use in forming a pre-press proof ( ) which comprises laminating at least one surface of a lamination envelope ( ) with a pre-laminate sheet ( ) comprising a first thermoplastic layer ( ) and a first support layer ( ) having a first release layer ( ) and first support base ( ), forming a lamination sandwich ( ). The first support layer ( ) from the lamination sandwich ( ) is removed forming a pre-lamination envelope ( ). A stiffener sheet ( ) is laminated to the pre-lamination envelope ( ) forming an improved lamination envelope ( ).

Lamination envelope

Laminating a pre-press proof ( ) onto a coated metal plate ( ), consisting of the steps of: laminating a pre-laminate sheet ( ) to a coated metal plate ( ). Removing the first support layer ( ) forming a pre-laminated receiver stock ( ). Creating an imaged receiver sheet ( ) laminating the imaged receiver sheet ( ) to the pre-laminated receiver stock ( ) thereby encapsulating the representative image ( ) and removing the second support layer ( ) forming a pre-press proof ( ) onto a coated metal plate ( ).
