    Abstract: This patent describes a lithographic printing plate comprising on a substrate a semisolid radiation-sensitive layer capable of hardening upon exposure to a suitable radiation, and a method of imaging such a plate using laser radiation. The utilization of a semisolid radiation-sensitive layer allows faster photospeed and better curing efficiency as desired for digital laser exposure. Several plate designs can be utilized to overcome the tackiness issue associated with the semisolid layer, such as conformally coating the radiation-sensitive layer on a rough substrate and utilizing an overcoat. Plates having an ink and/or fountain solution soluble or dispersible semisolid radiation-sensitive layer can be directly developed with ink and/or fountain solution while mounted on press, with the imagewise laser exposure being carried out on press or off press.
