Method for producing a customised volume reflection hologram, comprising the steps of: providing or producing a master, which comprises a carrier, at least one deflection structure, which is arranged on the carrier or is formed in the carrier, and covers a utility region, wherein the at least one deflection structure reflects coherent light of a wavelength incident onto the deflection structure from a specified incidence direction back into a specified drop-out direction which is not collinear to the incidence direction, wherein, in a back-reflection plane which is spanned by the incidence direction and the drop-out direction, the angle of the incidence direction to the surface normal of the macroscopic surface of the master deviates locally at an incident location of the coherent light from the angle of the drop-out direction against this surface normal, and comprises a reflection element, which reflects the directed light in accordance with the geometric optics; provision of a holographic film and arrangement of the film in front of the master, production of coherent light of the one wavelength; and directing of coherent light through the holographic film, such that at least a part of the coherent light radiates back at the deflection structure into the holographic film, wherein the shape of a register mark is modulated onto a further part of the light, and wherein this further part of the light onto which the register mark structure is spatially modulated is guided through the holographic film onto the master in such a way that this further part is reflected by the reflection element, reflecting in a mirroring manner in accordance with the geometric optics, wherein, independently of the specified incidence direction in which the one part of the light is radiated for the copying of the deflection structure, the further part of the light on which the shape of the register mark is modulated is guided perpendicularly through the holographic film and perpendicularly onto the reflection element, and wherein the method additionally comprises: receiving of customising data; and modulating of the coherent light in accordance with the customising data by means of a spatial light modulator in order to copy the utility area or a part thereof in a customised manner, wherein the modulating of the coherent light by means of the spatial light modulator produces the one part and the further part of the coherent light, and wherein the spatial light modulator modulates the shape of the register mark on the further part of the coherent light. providing or producing a master, which comprises a carrier, at least one deflection structure, which is arranged on the carrier or is formed in the carrier, and covers a utility region, wherein the at least one deflection structure reflects coherent light of a wavelength incident onto the deflection structure from a specified incidence direction back into a specified drop-out direction which is not collinear to the incidence direction, wherein, in a back-reflection plane which is spanned by the incidence direction and the drop-out direction, the angle of the incidence direction to the surface normal of the macroscopic surface of the master deviates locally at an incident location of the coherent light from the angle of the drop-out direction against this surface normal, and comprises a reflection element, which reflects the directed light in accordance with the geometric optics;
