Abstract: A process for preparing a waterless lithographic printing master is provided. A suitable substrate which is preferably ink accepting is coated with a silicone which is curable at low or ambient temperature and which contains in addition to its own catalyst a high temperature catalyst. The silicone is then cured at least on its surface to render it nontacky. A particulate image pattern is deposited on the cured silicone which pattern comprises a material which at elevated temperature combines with the high temperature catalyst to degrade the cured silicone below said image pattern, the composite heated to degrade the silicon below the image pattern and render the nonimaged areas ink releasing to the extent the silicone was not previously rendered ink releasing, and the particulate image pattern and preferably the degraded silicone removed beneath said pattern to reveal the ink accepting substrate in image configuration.

Abstract: A process is provided for forming waterless lithography printing masters comprising depositing a particulate image pattern on a non-tacky rubbery uncured silicone polymer, converting the non-tacky polymer into a softened gummy state and curing said softened polymer to fix the toner thereto.

Abstract: A process for preparing a gravure printing member is provided in which a multi-celled member, such as a gravure ink roller, containing a liquid but hardenable material below the contact plane of the cells is contacted with an electrostatographic latent image member, the members separated whereby the liquid is removed from the image areas of the celled member by electrostatic attraction and the liquid hardened in the non-image areas of said celled member to provide the printing member.
