A method for obtaining a curved laminated glazing unit, includes applying an enamel coating to a part of a first face of a first glass sheet so as to create at least one enameled zone and at least one unenameled zone, applying a sacrificial layer to a part, called the sacrificial zone, of a first face of a second glass sheet, simultaneously bending the first and second glass sheets, the sacrificial zone being disposed at least in line with at least one part of an enameled zone, removing the sacrificial layer, either during the bending or after the bending step, and laminating the first and second glass sheets by a thermoplastic interlayer.
