Abstract:
A combination digital/analog color proofing method comprising the steps of:(a) digitally forming a color thermal image on a receiver element comprising a receiver support and an image receiving layer; (b) attaching the digitally formed image with a film comprising a support having a release surface and a thermoplastic polymer layer; (c) removing the support thereby revealing the thermoplastic polymer layer, and leaving the digitally formed image encased between the image receiving layer and the thermoplastic polymer layer; and (d) attaching an analog color image to the revealed thermoplastic polymer layer to create a color proof comprising the combination of the digital and analog images; â€ƒthe analog image being prepared by: (i) imagewise exposing a photosensitive element to actinic radiation through a separation transparency, wherein the photosensitive element comprises: (1) a first photosensitive layer; (2) a support having a release surface; (ii) toning with a toning material to form an analog colored image on the first photosensitive layer, the separation transparency being prepared by the following steps, in order: (1) imagewise exposing to laser radiation an assemblage, under vacuum, comprising: (a) a backing film; and (b) a transparency forming element in contact with the backing film; said element comprising: â€ƒ(1) cover sheet â€ƒ(2) a black pigmented layer, and â€ƒ(3) a support; (2) separating the cover sheet from the support in transparency forming element (b), whereby the unexposed areas of the black pigmented layer are left behind on the support of the transparency forming element to form the separation transparency.
