A coated lithographic printing plate comprises a grained, anodized aluminum substrate and coating thereon comprising a diazo resin in admixture with particulate energy absorbing material that will absorb incident radiation and re-radiate it as radiation that will change the diazo resin coating which is imageable with a Crosfield Datrax 760 YAG laser plate maker producing incident radiation of 1/06 microns. The topography of the substrate and the particulate material in the coating trap and convert a substantial portion of the incident laser radiation which passes through the coating without substantially affecting same into radiation that will change the coating.
