A cylinder is arranged to receive one or more hollow cylinders on an outer surface of the cylinder. The cylinder has at least one movable stop with at least one movable element. In an idle position the at least one movable element does not protrude beyond the outer surface of the cylinder and allows hollow cylinders to be slid over the cylinder, and in an active position it protrudes beyond the outer surface of the cylinder and acts as a mechanical stop for hollow cylinders. The at least one movable element can be moved from the idle position to the active position, and vice versa, by means of a rotary movement. A method for positioning a hollow cylinder on a cylinder of this kind.

Devices are provided for aligning magnetic or magnetizable particles, which particles are contained in a coating that is applied on one side of a substrate, which substrate is in the form of a web or sheet. The device has a magnet cylinder, which is arranged in a transport path of the substrate to be conveyed and, in a region of the outer circumference of the magnet cylinder, the device has a plurality of devices for effecting a magnetic field, or magnet devices for short. Some or all of the magnet devices comprise a magnet which is rotatable by an associated motor. The magnet cylinder is rotatably arranged in frame walls of a frame. At least one transducer for contactless transfer of electrical energy or control signals from the outside is provided in or on the rotating magnet cylinder, which comprises a first transducer part fixed to the frame and a second transducer part fixed to the cylinder during operation.

An apparatus and methods of decorating a metallic container are provided. More specifically, the present invention relates to apparatus and methods used to provide a decoration on a predetermined portion of a metallic container body. The decorator includes a sensor that senses decorations on metallic containers. A control system receives information related to the sensed decorations from the sensor and then determines if the decorations at least meet predetermined color, density, thickness, orientation, and consistency targets. The control system can automatically adjust elements of the decorator to correct a deficient decoration. In one embodiment, the control system can automatically adjust ink blades associated with a plurality of inking assemblies of the decorator to adjust the color, density, orientation, positioning, and consistency of decorations transferred to the metallic containers. In another embodiment, the control system can adjust a position of an inking assembly, an ink roller, a plate cylinder, a printing plate, a blanket cylinder, and a transfer blanket of the decorator.

There is described a process of measuring print-to-print register of a multicolour print (A-D) provided in an effective printed area (EPA) of the surface of printed material, which multicolour print (A-D) is formed on the printed material by means of one or more printing presses and includes at least a first pattern (A) and a second pattern (B) distinguishable from the first pattern (A), the effective printed area (EPA) being provided with a matrix arrangement of individual imprints (P) which are each provided with the multicolour print (A-D) and are repeated over the surface of the effective printed area (EPA) along a pattern of rows and columns. Measurement of an actual print-to-print register between the first and second patterns (A, B), as reflected on the printed material, is derived from processing and finding a correspondence between (i) at least one sample image (SI.sub.A, SI.sub.B) of the printed material covering at least a portion of the first and second patterns (A, B), and (ii) at least one corresponding reference image (RI.sub.A, RI.sub.B) generated using prepress design data of the first and second patterns (A, B). Furthermore, the process is repeated for multiple ones of the individual imprints (P) so as to derive a set of multiple measurements of the actual print-to-print register between the first and second patterns (A, B) at various imprint locations over the effective printed area (EPA), which set of multiple measurements is mapped into a corresponding print-to-print register map (M.sub.B-A, M.sub.C-A, M.sub.D-A, . . . ) that is representative of print-to-print register deviations at the various imprint locations. Also described is a measuring device for carrying out this process and a process of measuring and correcting print-to-print register of a multicolour print.
