A method for mounting a printing master on a printing form cylinder includes readying a new print job with a printing-image length by releasing an unwinding spool, activating an unwinding spool drive for moving the printing master a length in circumferential direction of the cylinder on the circumferential surface by drawing the printing master to a rewinding spool and braking the unwinding spool for building tension. A preceding job image start is located on the surface facing the rewinding spool. A control device activates the unwinding spool drive and, before activation, data is produced in the control device regarding the length to be spooled forward, and the spools are fixed, after advancing the printing master a length, for insuring tension. A value is determined for the printing master length to be spooled forward, being at most the printing image length of the preceding print job plus a printing image spacing.

A device for recognizing functional units in an electrical system, which is one of being optional and provided in different construction stages, respectively, comprising a data processing unit and at least one functional unit, the functional unit having a function register with a nonvolatile memory for holding function data, the memory having at least one function entry with function data associated with the physical properties of the functional unit, a change in the properties of the functional unit being recordable by changing the corresponding function data of the function entry in the function register; and a method of operating the device.

Device containing a functional unit that stores function data representative of its properties and a data processing program for operating with required function data

A method for printing includes a plurality of process steps. According to an additional step, relevant data are stored in a central relational database. Both a printing press and a data processing unit processing prepress data are interconnected.
