<p>An aluminum alloy suitable as a base for printing plates consists essentially of aluminum containing iron (Fe) and manganese (Mn), the Fe content being 1.2 to 2.1% by weight, the Mn content being 0.1 to 0.9% by weight and the sum of the Fe and Mn contents being 1.3 to 2.2% by weight. A printing plate can be produced with such a base, the base being mechanically, chemically and/or electrochemically roughened and if required, anodically oxidized and hydrophilized. The printing plate includes at least one radiation-sensitive reproduction layer applied on the base.</p> |
