    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 associate 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 or dispersible semisolid radiation-sensitive layer can be directly developed with ink and/or fountain solution while solution while mounted on press, with the imagewise laser exposure being carried out on press or off press.

    Abstract: Provided are methods of imaging a wet positive working lithographic printing member comprising the steps of providing a positive working printing member comprising a substrate, a hydrophilic layer, an infrared-absorbing layer, and, optionally, an ink-accepting surface layer; exposing the printing member to infrared layer imaging in an imagewise pattern removing by ablation not greater than 10% by weight, and most preferably none of the infrared-absorbing layer and optional ink-accepting surface layer; and removing with water the laser-exposed areas of the infrared-absorbing layer and optional ink-accepting surface layer to reveal the underlying hydrophilic layer. These methods are advantageous in reducing airborne debris and vapors during laser imaging, in increasing the speed of laser imaging, and in providing excellent cleanability and image quality. The printing member may further comprise a primer layer underlying the infrared-absorbing layer with an adhesion-promoting agent present in the primer layer. Also provided are methods of preparing a wet lithographic printing member and wet positive working lithographic printing members prepared according to the methods of this invention.
