The raised edge part of a deep-drawn plastic cover is printed by pressing a carrier of a resilient deformable material, carrying a coloring composition, against the raised edge part. An apparatus for manufacturing the plastic cover comprises a deformable carrier for carrying a coloring composition. The carrier is integral with a cylindrical part connected with a first cylinder. Two concentric cylinders, positioned around the first cylinder at either side thereof, deform annular parts of resilient material and press these annular parts against the raised edge part when, on the one hand, the first cylinder and, on the other hand, the two concentric cylinders are moved with respect to each other. The coloring composition may also be carried by a layer-shaped carrier material. |
