ABSTRACT:
An apparatus for dry printing onto a workpiece (12) using a hot embossing film (10) and an emobssing die (1) is shown, whereby the hot embossing film (10) adheres onto the workpiece (12) corresponding to the embossing die (1) and after a cooling period the film, except for the impression itself, is released from the workpiece. The walls of the die body (2) are so thin that, as it is placed onto the workpiece (12) to be printed onto, it forms locally and elastically onto the workpiece surface (11). The side of the die body (2) facing away from the die face (3) displays a positive force transfer relief (7), which corresponds to or which is similar to the die face (3). On the side of the die body (2) facing away from the die face (3) there is an elastic pressure pad (8) for the die body (2) to form locally and elastically.
