Abstract:
A method for laminating a dual sided pre-press proof comprising:laminating a first side of a receiver stock with a first pre-laminate sheet, wherein said first pre-laminate sheet has a first pre-laminate sheet support layer, a first thermoplastic layer, and a first pre-laminate sheet release layer; laminating a second side of said receiver stock with a second pre-laminate sheet, wherein said second pre-laminate sheet has a second pre-laminate sheet support layer and a second pre-laminate sheet release layer; removing the first pre-laminate sheet support layer and said second pre-laminate sheet support layer forming a pre-laminated receiver stock; creating a first imaged clear receiver sheet with a first clear support layer, a first clear release layer, a second thermoplastic layer, and first image registration mark; and a second imaged clear receiver sheet with a second clear support layer, second clear release layer and second image registration mark; laminating said first and second imaged clear receiver sheets to said pre-laminated receiver stock, with the first and second imaged clear receiver sheets on opposite sides of the pre-laminated receiver stock overlapping said pre-laminated receiver stock such that the registration marks on the first and second imaged clear receiver sheets are visibly positioned on top of each other and are in registration with each other; and removing said first clear support layer and said second clear support layer forming a dual sided pre-press proof, wherein said images are in registration with each other.
