The graphic security marking has at least two lines (3,4) which intersect at least at two points (3,4) on a substrate (5). The overlays (6,7) at the line intersection points (1,2) differ from each other. The lines (3,4) are in different colors, and the substrate (5) is transparent. The lines (3,4) have a dia. of /-20 mu m so that the lines and their overlay (6,7) at the intersections can be felt.
