The invention provides a preparation method for a film-covered iron printing forme, comprising the following steps of: obtaining a pre-deformed picture according to anisotropism of a film-covered iron plate material; and attaching the pre-deformed picture on a film-covered iron plate which is to be subjected to cup stamping, and then performing the cup stamping. According to the preparation method for the film-covered iron printing forme, provided by the technical scheme, the film-covered iron plate is divided into a non-deformed area, a uniformly-deformed area and a non-uniformly-deformed area according to the anisotropism of the film-covered iron plate, and then the pre-deformed picture is attached on the film-covered iron plate; and via the accurate division aforementioned for each deformed area, the picture deformation caused by the cup stamping just can be neutralized with the picture deformation caused by the pre-deformation treatment during the cup stamping, so that the picture formed after the cup stamping cannot deform.
