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.

Abstract: A method of forming a color-proofing surprint includes the image-wise light exposing of an imaging sheet having a photoresist top layer, removing by the application of developer fluid the more soluble areas remaining after light exposure, thereby revealing image-defining areas of an underlying layer of pressure-sensitive adhesive, and applying a powdered colorant to such image-defining areas of adhesive. The residual areas of the photoresist layer may then be removed to reveal the non-imaged areas of the adhesive layer and the image-bearing adhesive surface of the sheet pressed into adhesive contact with a receiving surface. Removal of the original carrier film of the imaging sheet from the adhesive layer renders this layer accessible to receive, in image registration, the image-bearing adhesive layer, in different color, of a separate imaging sheet.
