Abstract: A negative-working, imageable element comprises a substrate and an IR-sensitive imageable layer comprising a dispersion of nanofibers of a preformed IR-sensitive polymer. The nanofibers can be composed of polyaniline, polypyrrole, or polythiophene. The IR-sensitive imageable layer containing the nanofibers can be imaged using infrared radiation and used for printing without further processing. Thus, both imaging and printing can be carried out on-press.

Abstract: A method of developing a laser sensitive lithographic printing plate with ink and/or fountain solution is described. The printing member comprises on a substrate a photosensitive layer soluble or dispersible in ink and/or fountain solution and capable of hardening upon exposure to a laser. The plate is exposed with a laser and deactivated under a safe light or in the dark, and then on-press developed with ink and/or fountain solution preferably under white light. Alternatively, the plate is developed with ink and/or fountain solution or the likes off press, and then mounted on press for lithographic printing.

Abstract: A lithographic printing press having a plate cylinder in a substantially light-tight compartment suitable for on-press imaging and developing a laser sensitive plate is described. The plate cylinder as well as certain other press parts is covered by non-transparent and/or safe-light-passing-only covers so that no or only limited amount of unsafe light passes onto the plate mounted on the plate cylinder during on-press imaging and development. The plate comprises on a substrate a photosensitive layer soluble or dispersible in ink and/or fountain solution and capable of hardening upon exposure to a laser having a wavelength selected from 200 to 1200 nm. The plate is on-press exposed with the laser, developed with ink and/or fountain solution, and then directly prints inked images to the receiving sheets.

Abstract: A primer layer that includes a surface-tension modifier dispersed within a polymer binder is disposed between the imaging layer and the substrate of a lithographic printing member to inhibit the production of thermal degradation products that disrupt the oleophilicity of the exposed imaged areas, thereby improving print-making performance and efficiency. In addition, embodiments of the primer layer inhibit static charge buildup during production and during the print-making process.
