    摘要: Correcting register faults in a multicolor printing machine having a number of items of equipment for the digital production of color separations, wherein correction values are determined and assigned to angular positions of at least one image cylinder and, as a result, taken into account for the control of the production of the color separations on the image cylinder. Correction values are to be made available for the correction of register faults, which, with a fine graduation, make it possible to assign them to angular positions of machine elements in a repeatable way. This is achieved by determining circularity errors of machine elements which have an influence on the register, assigned to their angular positions and, from these, the correction values for the control of the production of the color separations on the at least one image cylinder being determined.

    摘要: Apparatus for precisely positioning one or more of the workstations of a document printer/copier relative to an internal drum, including a first member, attached to either a workstation or the internal drum, having two sections, each section having a reference surface forming an angle therebetween, an actuator for changing the included angle between the first reference surface and second reference surface, thus enabling the included angle to be increased or decreased, and a second member having a reference surface that mates with the pair of reference surfaces, associated with the other of the workstation or the internal drum, so as to accurately adjust the workstation relative to the internal drum dependent upon the included angle of the first reference surface and second reference surface.
