A cover for a device is disclosed. 2:1 to about 2:1, and b) an image-receiving layer having particles and a cross-linkable polymer containing hydroxyl groups, the cross-linkable polymer being present in an amount of from about 20 to about 150 gm2, and the weight ratio of the cross-linkable polymer to the particles is from about 10:90 to about 30:70. In a first mask subregion, a first pattern-element portion is defined having a mating end that is complementary to a mating end of a second pattern-element portion defined in a second mask subregion. The ball is wirebonded to the sides and bottom of the wire bond cavity. Furthermore, the lamp can be a dielectric barrier discharge excimer lamp which has electrodes for carrying out a dielectric barrier discharge and a discharge vessel which is filled with krypton gas and chlorine gas, and which has emission wavelengths between 200 nm and 230 nm.
