Abstract

The invention relates to an object comprising a substrate (2) and a scale (3) which is applied onto the substrate (2) using a printing medium which has magnetizable and/or magnetic particles and which has regions that have the printing medium and regions (5) that are free of the printing medium. The scale is designed to indicate positions by means of the regions which have the printing medium and the regions (5) which are free of the printing medium. The magnetic properties of the substrate (2) are such that when an external magnetic field is applied to the object (1) or when the magnetic field of the magnetic particles from the printing medium is read, a stronger magnetic field is generated than that of the substrate (2).
