The description relates to a process for the simulta- neous replication and direct application of holograms and other diffraction grids on various printing material (6), especially paper or cardboard. It is carried out in the shaping process using a matrix bearing the hologram as a surface relief structure. One or more coats of lacquer (3, 7, 9) are applied to a printing material (6) with a sub- stantially smooth surface and thus the surface of the printing material (6) is smoothed further. The hologram is simultaneously shaped into the surface of the coating applied to the printing material (6). The lacquer coating (3) can be hardened by radiation and the lacquer costs (3) are hardened from the matrix side through the UV-transpar- ent matrix and through a matrix support (14) (a plate or cylinder) which is also UV-transparent. The lacquer coat(s) (3, 7, 9) is/are essentially hardened before the printing material (6) is removed from the matrix and in contact with the matrix or the shaping cylinder.
