Plates coated with compositions photothermally sensitive to multiple portion s of the electromagnetic spectrum and useful for the preparation of lithograph ic printing plates, color proofing films and the like by computer to Alate imaging processes comprising a solvent, cross-linkable polymers and monomers , and energy absorbing dye/laser dye/initiator/sensitizers, where the energy absorbing dye/laser dye/initiator/sensitizers are selected from dye/initiator/sensitizers having increased sensitivities to varying portions of the electromagnetic spectrum and where the sensitivity of the imaged Alat e is increased by Are-heating prior to development.
