A method for coloring or figuring a surface of a soft magnet includes steps of: preparing a soft magnet having a surface to be colored or figured; previously printing a color layer or a figure layer on a surface of a low-extensibility medium material; disposing an elastic attachment material layer on a surface of the color layer (or the figure layer) or the surface of the soft magnet; and stamping the medium material and the soft magnet to detach the color layer or the figure layer from the medium material and affix the color layer or the figure layer to the surface of the soft magnet via the elastic attachment material layer at high adhesion. During the stamping process, the soft elastic attachment material layer is expandable to absorb the expansion of the soft magnet to overcome the problem of poor precision existing in the conventional soft magnet printing operation. |
