Abstract

A process of forming a halftone color proof containing at least one dye transfer image and at least one pigment transfer image, comprising imagewise-exposing, for less than about 10.sup.-4 sec., by means of a laser having a power density of greater than 10.sup.4 W/cm.sup.2, a dye-donor element comprising a support having thereon a dye layer comprising a dye dispersed in a polymeric binder, the dye layer having an infrared-absorbing material associated therewith, the laser exposure taking place through the side of the support of the dye-donor element which does not have the dye layer thereon, and transferring a portion of the dye in the dye layer to a receiving element having thereon an image-receiving layer; and imagewise-exposing, for less than about 10.sup.-4 sec., by means of the laser, an ablative or propulsive pigment-donor element comprising a support having thereon a transfer layer comprising a pigment dispersed in a binder, the transfer layer having an infrared-absorbing material associated therewith, the laser exposure taking place through the side of the support of the pigment-donor element which does not have the transfer layer thereon, and transferring a pigment image to the receiving element to obtain the halftone color proof.
