Abstract
Most prepress color proofing systems require the use of special receptor sheets. The differences between the special sheets and the final print sheet can affect the desired color balance. The use of a proof image on a temporary transfer sheet, with an adhesive layer between the image and a final receptor layer, enables the use of essentially any printing stock or printing surface as the final proofing image substrate.
