Method for determining the position of an edge surface of e.g. boardlike objects (11) arranged in a pile (12) and for marking the objects by means of a print head, in which method the height of the edge surface and/or its positi on in space is measured by means of a measuring element, in which method the actual deviation of the edge surface (13) from a theoretical basic plane is determined by measuring the spatial coordinates of the edge surface, and the movements of the print head are controlled using the information thus determined so that its distance from the marking point remains at a desired or a substantially constant value.
