A composite aluminum sheet for a presensitized lithographic printing plate comprises a support such as a thermoplastic sheet and an aluminum foil which has a matt surface with a roughness of 0.20-0.65 mu m Ra on one side thereof and is prepared by twice or more repeatedly pack rolling doubled aluminum foils, the support being overlaid with the aluminum foil so that the matt surface thereof faces outside. A presensitized plate for lithography having excellent printing properties such as printing runnability can be prepared from the composite aluminum sheet. |
