Abstract
Seamless, sleeve-shaped dry and wet lithographic printing members that can be recycled after use along with methods for their manufacture and use. The members include a strong, durable, hollow cylinder or sleeve that is attached to the plate mandrel or cylinder jacket of an offset printing press or platemaking apparatus. Surrounding the sleeve is a layer of a material, preferably polymeric in nature, which is characterized by efficient, ablative absorption of laser radiation, as well as other layers that facilitate imaging and subsequent printing.
