<p>A lithographic printing plate material excelling in on-press development performance, exposure visible image properties, printing wear resistance, scumming prevention and scratch resistance; and a method of printing therewith. There is provided a lithographic printing plate material comprising a plastic support and, superimposed thereon, a hydrophilic layer and an image forming layer, characterized in that the image forming layer contains a polyolefin wax of 105 to 120°C melting point and 1 to 1200 mPa·s melt viscosity, and that the hydrophilic layer contains spherical silica particles of 5.0 to 7.0 µm diameter, the ratio of contained spherical silica particles of 5.0 to 7.0 µm diameter to all particles of 2 to 10 µm diameter contained in the hydrophilic layer being = 60%.</p> |
