A method for selecting a service provider for a service, which can be received by a mobile station via a radio access network and which is provided by at least two service providers, as well as to a corresponding selecting device are shown. The communication mechanism is provided between a protocol family and the process, and is capable of communicating with both. A compensation pattern according to this invention has a plurality of halftone regions that are lead by, trained by, and separated by rows of fiducial marks. The associated low-temperature, normal-pressure process produces few harmful materials and may be easily employed for production of ZnO nanoparticles. The weighted dot distribution in the direction different from the scanning direction of the print head thus does not significantly affect the resulting picture quality even in the event of some positional misalignment of dot formation and ensures a high-quality printed image.
