Method for laminating overlays to verify printing plates

Abstract

A method of forming an overlay ( 310 ) having a surface energy charge for verifying an image ( 210 ) on printing plates ( 300 ) formed by creating an imaged receiver sheet ( 140 ) having an image, a first thermal print layer ( 224 ), and a first support layer ( 150 ). An imageless receiver sheet ( 160 ) is laminated having a second thermal print layer ( 228 ) and a clear second support layer ( 170 ) with the imaged receiver sheet thereby encapsulating the image. The first support layer is removed.

What is claimed is:  
     
         1 . An overlay having a surface energy charge for verifying an image on printing plates formed by the method consisting of: 
 a) creating an imaged receiver sheet having an image, a first thermal print layer, and a first support layer;    b) laminating an imageless receiver sheet having a second thermal print layer and a clear second support layer with said imaged receiver sheet thereby encapsulating said image; and    c) removing said first support layer.    
     
     
         2 . The overlay of  claim 1  wherein said first support layer comprises a first support base, a first release layer, and a first aluminized layer.  
     
     
         3 . The overlay of  claim 1  wherein said imaged receiver sheet comprises monochrome images.  
     
     
         4 . The overlay of  claim 1  wherein said imaged receiver sheet comprises a multicolor image.  
     
     
         5 . The overlay of  claim 1  wherein said thermal print layer sheet has a thickness ranging from 1 to 75 microns.  
     
     
         6 . The overlay of  claim 1  wherein said imaged receiver sheet has a high resolution of between about 1400 and about 4000 dpi.  
     
     
         7 . The overlay of  claim 1  wherein said imaged receiver sheet has a high resolution of between about 1800 and about 3000 dpi.
