  • Aluminium strip for lithographic printing plate carriers comprising water-based coatings
    Patent number: 8857332
    Abstract: The invention relates to an aluminum alloy strip for the production of printing plate carriers comprising water-based coatings, wherein the aluminum alloy strip has a thickness of at most 0.5 mm. The object is to propose an aluminum alloy strip for the production of printing plate carriers comprising at least one water-based coating so that punctiform coating faults are prevented. The object is achieved for an aluminum alloy strip in that the aluminum alloy strip, in a longitudinal polished section prepared using water as a lubricant, has etch figures with a cubic etching, of which the longitudinal extent is at most 15 mm.
