A method for extracting and colour correcting digital image information from prepress CIP3 or similar final imposed files. A primary ideal image is displayed in comparison with a secondary image which is iteratively updated using spectrophotometric data gathered by reading press sheets with a colour bar scanning device. This reduces the need for hard copy colour proofs press side while eliminating the need to interpret differences between conventional hard or soft proofs versus printed materials. A prepress image data file representing final approved colour content is digitally transferred to a press side computer. Personnel manually select the appropriate file which is automatically adjusted to visually reflect the final anticipated printed colour and is displayed as the primary image on a monitor. The secondary image colour is controlled through application of CIELAB values from a colour bar scanning device. Both images are viewed simultaneously for visual comparison.
