Patent ID: 8900680

Claim:
A packaging material comprising a plurality of magnetic marks printed thereon comprising at least one magnetic mark per package to be formed from the packaging material, and said at least one magnetic mark providing a magnetic field pattern and being aligned with a preparation feature associated with an operation to be made to finish packages, wherein said at least one magnetic mark is positioned on the material such that relative speed between the material and means for reading the magnetic mark is varying, nonzero during reading, wherein the magnetic field pattern comprises a first magnetic field peak having a first polarity and a second magnetic field peak having a second opposite polarity, and wherein the material defines a transversal direction parallel to an imaginary axis of a roll when a web of the material is spooled, a longitudinal direction perpendicular to the transversal direction, and an imaginary line between a midpoint of the first peak and the second peak of the magnetic field pattern, and the magnetic field pattern is arranged such that the angle between the imaginary line and the longitudinal direction is between −10 and 10 degrees.
