摘要

A novel flexible lithographic printing tape has a surface of a zirconium oxide ceramic, which is alloyed with one or more of MgO, CaO, Y2O3, Sc2O3 and rare earth oxides as secondary oxide and which has 5.6-6.2 g/cm<3> density, the tape having an average thickness of less than 5 mm. Also claimed are imaging and lithographic printing processes employing the above printing tape.
