ABSTRACT:
The present invention provides a lithographic plate material for a hot-melt type ink-jet printer, characterized in that it comprises an image receiving layer provided on a surface of a flexible plastic film, the image receiving layer being receptive of hot-melt compounds constituting a hot-melt type ink. The image receiving layer, preferably, comprises at least a polymer binder, a pigment becoming hydrophilic upon etching with an etching solution and one or more pigments for imparting unevenness to the surface of the layer. This lithographic plate material is made into a lithographic plate by using the hot-melt type ink-jet printing system. By using this printing system, occurrence of unwanted background image can be completely prevented because there is no possibility of scattering of toner due to electrostatic charging upon peeling.
