The invention relates to an aluminium alloy strip for the production of printing-plate carriers with water-based coatings, wherein the aluminium alloy strip has a thickness of at most 0.5 mm. The problem is to propose an aluminium alloy strip for the production of printing-plate carriers with at least one water-based coating, with the result that punctiform coating faults are prevented. The problem is solved for an aluminium alloy strip by virtue of the fact that the aluminium alloy strip has etching figures with a cubic etching attack, in a longitudinal section prepared with the use of water as lubricant, the longitudinal extent of which etching figures is at most 15 [mu]m.
