A method for automatically determining the exact position of register marks

A method for automatically determining the exact position of registration marks, wherein at least a part of a registration mark is detected digital, characterized in that edges of at least one component (101, 102, 103) determines the detected registration mark and on either side of the component (101, 102, 103) the gradient of the edges are formed and (to determine the position of the component 101, 102, 103) of the registration mark the line of intersection of two surfaces is formed of opposing, component limiting edges are approximately the two to the gradient.
