Abstract A process is described for producing a direct digital, halftone color proof of an original image on a dye-receiving element, the proof being used to represent a printed color image obtained from a printing press, comprising: a) generating a set of electrical signals which is representative of the shape and color scale of an original image; b) contacting a dye-donor element comprising a support having thereon a dye layer and an infrared-absorbing material with a first dye-receiving element comprising a support having thereon a polymeric, dye image-receiving layer; c) using the signals to imagewise-heat by means of a diode laser the dye-donor element, thereby transferring a dye image to the first dye-receiving element; and d) retransferring the dye image to a second dye image-receiving element which has the same substrate as the printed color image.
