The invention relates to black plate for producing deep-drawn parts for packaging purposes, especially lids for drink containers and/or for food or drink containers. A surface of the black plate contains a raised section (14) which has a ring-shaped peripheral profile as seen from above or which has a flat extension whose boundary corresponds to the peripheral profile of reinforced areas of the deep-drawn part to be produced. The height and profile of the raised section can be chosen simply by a person skilled in the art, in such a way that the thickness of the black plate does not fall below the necessary thickness for stability in the areas which are considerably stressed and therefore stretched, and whose thickness is reduced during the deep-drawing process. This also enables the desired reinforcements to be prepared in particular surface areas of the finished deep-drawn part to be produced. At the same time, the thickness of the black plate outside of the raised sections (14) can be chosen in accordance with the stability that is required in these areas, e.g., for the flat, middle area of a lid. The advantage is a saving in material.
