A product has a coding pattern on its surface. The coding pattern may include symbols representing at least two different values and where each symbol comprises a raster point and at least one marking. The raster point is included in a raster that extends over the surface and the value of each symbol is indicated by the placement of the marking in relation to the raster point. The markings may each have a spatial extent that, in combination, may at least partially form the image.
