Abstract
Printing and printed circuit board members and a method for producing printing member from a member is provided. The printing member includes a topmost protective layer, an IR ablatable layer, a substrate and a wash-off layer. The wash-off layer is washed with a solvent after imagewise ablation of the topmost protective layer so as to expose the substrate, so that the printing member is produced. In one embodiment, the IR ablatable layer is disposed above the topmost protective layer and the wash-off layer is intermediate the topmost protective layer and the substrate
