For manufacturing a multilayer structure (28) with a clear window (30), a layer (12) of non-opaque plastic material is provided. This non-opaque layer (12) has a region (15) with an extra-thickness formed by embossing. The non-opaque layer (12) is covered with at least one compensation layer (22) having a window (25), with the region (15) with an extra-thickness in coincidence with the window (25). Other layers (24) are possibly laminated with the non-opaque layer (12) and the compensation layer (22). |
