Abstract
Laser-imageable lithographic printing members have rigid base supports that confer strength and rigidity. The supports may reflect imaging radiation so that radiation from an imaging pulse that passes through an imaging layer is returned to that layer, thereby augmenting the effective energy flux density. In the case of thermally conductive (e.g., reflective metal) base supports, heat is concentrated in the imaging layer by an underlying insulating layer interposed between the imaging layer and the base support.
