Abstract A process for producing a color image on color proofing film which comprises: (i) providing digital data representative of the shape and color of an original image; (ii) inputing the digital data into a computer; (iii) providing a color printer which is in communication with and controlled by the computer; (iv) providing the printer with a precoated photosensitive color proofing film, a thermal wax and means for transferring the wax to the color proofing film; (v) melting the thermal wax, in response to the digital data, in a manner which provides a pattern corresponding to the shape of the original image, the pattern providing a temporary wax optical mask; (vi) exposing the photosensitive layer of the color proofing film, through the thermal wax optical mask, to actinic radiation, the wax on the color proofing film absorbing the actinic radiation, whereby a photoreaction occurs in the exposed areas of the photosensitive layer of the color proofing film; and (vii) developing the color proofing film to provide a color image corresponding to the original image.
