Abstract

It has recently been discovered that if the non-imaged areas of the printing master are formed of an abhesive ink releasing silicone elastomer, ink will not adhere to said elastomer so that a fountain solution or dampening solution is no longer required. One difficulty encountered with these new silicone masters, however, is that it is difficult to image the master unless the silicone is removed in the imaged areas so as to permit printing from an underlying substrate, Thus, because the silicone is abhesive, particulate imaging materials such as toner cannot be easily adhered to the silicone.
