    摘要： The invention relates to a method for producing a master hologram (45) for a contact printing method, such a master hologram (45) and a method for producing individualized holograms (345) and individualized holograms (345) which are produced using such a master hologram (45) by way of the contact printing method. The method for producing a master hologram (45) comprises the following steps: arranging a diffuse scattering device (10), a stop (20), a Fourier lens (30) and a holographic recording material (40) on an optical arrangement axis (3) such that an optical axis (31) of the Fourier lens (30), a surface normal (41) of the holographic recording material (40) and a surface normal (26) of a stop aperture plane (25) of the stop (20) are collinear with the optical arrangement axis (3), wherein the stop (20) is arranged immediately adjoining the diffuse scattering device (10) between the diffuse scattering device (10) and the Fourier lens (30) and the diffuse scattering device (10) is arranged in the focal plane (32) of the Fourier lens (30) and coherent first light (110) is radiated onto the diffuse scattering device (10) in order thereby to generate the diffusely scattered light (115) which is delimited by means of the stop (10) and guided as object light (119) into the holographic recording material (40) by means of the Fourier lens (30) and second coherent light (120), coherent with the first coherent light (110), is radiated into the holographic recording material (40) as reference light (129) from a side facing away from the Fourier lens (30) in order to form a reflection volume hologram (45) in the holographic recording material (40).
