Abstract

A method for the surface treatment of flat products made of aluminium alloys. The method includes pickling the flat product, in particular for degreasing the flat product. The method includes carrying out a colour measurement on the surface of the flat product to determine at least one measured colour value after pickling the flat product. The method includes generating output information on the basis of the at least one measured colour value. The output information is indicative of compliance with at least one rule for the measured colour value and outputting or triggering the output of the output information. The invention further relates to a device for the surface treatment of flat products made of aluminium alloys and to a use of a colorimeter which is configured to determine at least one measured colour value in a surface treatment of flat products made of aluminium alloys.
