Abstract

Lithographic masters using xerography are provided, A coating consisting of a low melt resin containing a heat sensitive blowing agent is placed on a clear plastic film (mylar, polycarbonate, etc.) . A black toner image (xero~ graphic) is then deposited on this film (coated side) in the usual way and fused by flash or radiant fusing. By virtue of the film transparency, most of the light or heat will be absorbed in the image areas producing hot spots. These hot spots will then trigger local decomposition of the blowing agent causing the coating resin to be raised in the image area, This master can then be used to produce other copies by standard printing techniques.
