Plates coated with compositions photothermally sensitive to multiple portions of the electromagnetic spectrum and useful for the preparation of lithographic printing plates, color proofing films and the like by computer to plate 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 plate is increased by pre-heating prior to development.
