Abstract (en)
[origin: WO2011072403A1] The invention concerns a process for manufacturing a metering roll especially usable in flexographic printing presses, in varnish stations for offset presses and/or in short ink train dry offset presses for example, comprising a central cylindrical core (11) and at least one layer (12) of a hard material peripheral coating that is engraved by use of a laser beam. This process comprises at least a first step of melting superficially at least partially the hard material coating, a second step when the melted hard material solidifies and forms a flat surface free of engraving and a third step of engraving again the hard material coating with a laser beam within the re-melted zone.
