To produce a grating image for a security document, a contour line (9) is filled with hatching lines (11) with the help of a drawing program, grating coordinates are calculated from the intersection points between the hatching lines (11) and the contour line (9), and the such produced data records of the grating image are supplied to a lithography machine.
