The invention relates to a device (100) for the subsequent holographic marking of a composite body (1) and a corresponding method that comprises the following steps: providing or producing the composite body (1), which comprises a hologram layer (3) that is photosensitive at least in one region (7); arranging the composite body (1) on or in a retainer (101); exposing the composite body (1) to coherent radiation (162) that interferes in the photosensitive region (7) of the hologram layer (3) in order to record holographic information in the photosensitive region (7) of the hologram layer (3) by exposure; fixing the hologram recorded by exposure in the hologram layer (3). In order to be able to make high-quality contact copies, it is specified that a master (130) in the form of a film is used, said master being applied to a front side (12) of the composite body (1).
