Filter segments are mounted to the carrier. In addition the color rotor comprises a body with a surface perpendicular to the rotational axis of the rotor. The surface comprises a two dimensional matrix of holes which can be filled with balancing masses. In order to balance the color rotor it is rotated. During rotation, the unbalance is detected. In addition the location where to put balancing mass is detected. At this location balancing mass, such as for example adhesive is filled into the respective hole.
