Abstract
Abstract The finished surface of a multicolor surprint proof is made to exhibit a matte appearance and closely simulate the surface texture of the printing stock to which it is applied. Individual colored image adhesive layers are laminated in register to a receptor sheet which comprises a coated layer of film-forming polymer composition on a polyester carrier sheet having a matte texture surface. Subsequent to final adhesive lamination of the assembled surprint to desired printing stock, the receptor carrier sheet is stripped from the polymer film layer to yield a tough protective film overlayer which complements the matte texture of the original receptor carrier sheet surface and provides the desired matte appearance of the multicolor proof.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
126 words
The method of providing a matte finish on color-proofing surprints which comprises: (a) providing a receptor sheet comprising a carrier sheet presenting a matte surface and, coated on said carrier sheet, a layer of substantially transparent film-forming polymeric material in intimate contact with said matte surface; (b) providing a color-proofing surprint image comprising a carrier sheet and a colored image layer adhered to said surprint carrier sheet; (c) adhering said film-forming polymeric layer to said image layer in a union exhibiting greater adhesion than the adhesion between said polymeric layer and said matte surface; and (d) separating said receptor carrier sheet from said polymeric layer by peeling apart at said matte surface interface, thereby depositing a complementary matte-surfaced polymeric film adhered to said surprint image layer.
Claim 2
Independent Claim
126 words
The method of providing a matte finish on color-proofing surprints which comprises: (a) providing a receptor sheet comprising a carrier sheet presenting a matte surface and, coated on said carrier sheet, a layer of substantially transparent film-forming polymeric material in intimate contact with said matte surface; (b) providing a color-proofing surprint image comprising a carrier sheet and a colored image layer adhered to said surprint carrier sheet; (c) adhering said film-forming polymeric layer to said image layer in a union exhibiting greater adhesion than the adhesion between said polymeric layer and said matte surface; and (d) separating said receptor carrier sheet from said polymeric layer by peeling apart at said matte surface interface, thereby depositing a complementary matte-surfaced polymeric film adhered to said surprint image layer.
Claim 3
Dependent Claim
33 words
The method of claim 1 wherein said receptor sheet further comprises a layer of tacky pressure-sensitive adhesive coated on said polymeric layer, whereby adhesion between said image and polymeric layers may be effected.
Claim 4
Dependent Claim
164 words
In a method of preparing a multicolor proofing surprint which comprises adhering to a receptor sheet surface a registered composite of imaged adhesive layers, each comprising a colored powder imagewise adhered to a substantially continuous layer of tacky pressure-sensitive adhesive composition, the improvement which provides a matte finish on said surprint, said improvement comprising: (a) adhering to the imaged layer intended to be the farthest disposed from said receptor sheet the polymeric coated layer of a cover sheet comprising a carrier sheet presenting a matte surface and, coated on said carrier sheet, said layer of substantially transparent film-forming polymeric material in intimate contact with said matte surface, the resulting union exhibiting greater adhesion than the adhesion between the film of said polymeric material and said matte surface; and (b) separating said carrier sheet from said polymeric film layer by peeling apart at said matte surface interface, thereby depositing as the outermost viewing surface of said surprint the complementary matte surface of said polymeric film.
Claim 5
Dependent Claim
164 words
In a method of preparing a multicolor proofing surprint which comprises adhering to a receptor sheet surface a registered composite of imaged adhesive layers, each comprising a colored powder imagewise adhered to a substantially continuous layer of tacky pressure-sensitive adhesive composition, the improvement which provides a matte finish on said surprint, said improvement comprising: (a) adhering to the imaged layer intended to be the farthest disposed from said receptor sheet the polymeric coated layer of a cover sheet comprising a carrier sheet presenting a matte surface and, coated on said carrier sheet, said layer of substantially transparent film-forming polymeric material in intimate contact with said matte surface, the resulting union exhibiting greater adhesion than the adhesion between the film of said polymeric material and said matte surface; and (b) separating said carrier sheet from said polymeric film layer by peeling apart at said matte surface interface, thereby depositing as the outermost viewing surface of said surprint the complementary matte surface of said polymeric film.
Claim 6
Dependent Claim
34 words
The improvement according to claim 3 wherein said cover sheet further comprises a layer of tacky pressure-sensitive adhesive coated on said polymeric layer, whereby adhesion between said image and polymeric layers may be effected.
Claim 7
Dependent Claim
24 words
The improvement according to claim 3 where said film-forming polymeric material is selected from the group consisting of polyvinyl alcohol, polyvinylacetate, and polyamide resins.
