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. Repetition of the process with additional colored images renders a multi-colored surprint proof which may ultimately be affixed, by means of the final accessible adhesive surface, to any type of printing stock in order to provide a faithful example of the appearance of a press print on such stock.
