A method of manufacturing print products uses a computer and a printing or further processing machine with a network connection. A customer-requested print product is compared to digital print product models on the computer, and the best matching digital print product model is selected by the computer from the comparison between the saved digital print product models and the customer-requested print product. The computer checks digital print shop models for compatibility with the selected digital print product model, compares the digital print shop model selected as suitable to saved preference models of actual print shops and selects matching preference models of actual print shops for producing the customer-requested print job. After the customer's computer selects at least one suitable actual print shop, the customer-requested print job is produced on at least one printing or further processing machine of the print shop selected by the customer.

Method of manufacturing print products by digital identification of matching print shops

A method of producing printed products uses at least one computer and at least one input device for controlling at least one machine for processing printing substrates. The input device receives technical and economic data of at least one print shop and the computer receives customer preferences relating to print jobs by using the input device. Based on the technical and economic data of the print shop, the computer calculates a simulation of possible print jobs producible in the print shop. The computer takes into account the results of the simulation and the customer preference inputs and generates matching offers for print jobs. The computer compares the generated offers with customer print jobs and, if a match is found between an offer and a customer's print job, the print job is processed by the machine for processing printing substrates.

A sheet transport apparatus in a sheet processing machine has at least one driven transport belt for the transport of sheet printing materials from a first location to a second location. It being possible for the transport belt to be driven at different transport speeds. The acceptance of the sheet printing materials at the first location is carried out at a relatively low transport speed, and the transfer of the sheet printing materials at the second location is carried out at a relatively high transport speed.

A display and/or operating device for controlling machines includes a projection device for projecting an image onto a projection area, an acquisition device for scanning the same projection area, and a control computer for controlling the projection device and the acquisition device. The present invention is distinguished by the fact that, by the acquisition device and the control computer, an analysis of the same projection surface can be carried out, and that the content of the image to be projected can be controlled by the control computer as a function of the result of the analysis of the same projection area.

Projection-area dependent display/operating device

A method is provided for synchronizing drive combinations having a plurality of drives for machines. The drives include at least one master drive and a plurality of slave drives assigned to the master drive. A central control unit is provided, as well as controls for each of the drives, including data processing and storage equipment. The slave drives are synchronized with respect to at least one of rotational speed and angular setting as prescribed by the master drive. The steps of the method, depending upon operating values of the master drive, include determining at least one synchronization function for each of the slave drives, determining master-synchronous operating values for each operating time for the respective slave drive with the synchronization function, and prescribing the determined operating values for the respective drive. A device for performing the method is also provided.

A method for automatically exchanging a printing plate () in a print unit of a rotary press having a blanket cylinder () and a plate cylinder () carrying the printing plate includes disengaging the plate cylinder from the blanket cylinder; reducing the speed of the plate cylinder (v_P) to a rendezvous speed (v_R) which is greater than 0; automatically clamping the printing plate onto the plate cylinder at the rendezvous speed (v_R); and increasing the speed of the plate cylinder (v_P) to a printing speed (v_DG).

The present invention relates to a device and a method for synchronizing processes which are executed on a plurality of units (), in particular, in paper-processing machines, the units () being connected to a central control unit () via a data bus (). The present invention is characterized in that the central control unit () is designed for distributing movement commands via a data bus () to a plurality of units (), the movement commands containing the instant at which these commands are executed, and that provision is made for the units () which keep available the absolute time to synchronously execute these commands at the instant communicated via the commands.

A device and method for synchronizing at least two printing-unit groups (2, 3) which represent a sheet-fed printing machine (1). Between the two printing-unit groups (2, 3) there is provided a transfer unit (10) being operable by means of a separately controllable drive (12). The present invention is used in sheet-fed printing machines assembled in serial arrangement.

Device and method for driving a printing machine with multiple uncoupled motors

A printing machine, which includes at least two printing unit groups having drives which are decoupled from one another and assigned, respectively, to one printing unit group, and having printing units with transfer cylinders, include compensation elements for compensating for speed differences and positional errors between two printing unit groups. The compensation elements are assigned to a printing unit group which is an accepting printing unit group, in order to compensate for transfer errors.

In order to achieve a good printed result, it is important that the rollers that interact with each other are arranged at a suitable distance from each other, so that they act on each other with the pressure as stipulated. In order to set the rollers, use is made of a stripe, in particular an ink stripe, which results from contact between the rollers in the rest state. After the transfer, i.e., the formation of the strip, the relevant roller must be rotated into a position wherein the printing machine operator can have access to the ink stripe. As a result of the safety devices provided in printing units, it is generally not possible to detect, however, when the ink stripe on the roller appears in the suitable position. The invention provides a remedy here, in that it is proposed to rotate the roller into the viewable position at a suitable speed, or, by using a special program, taking into account a predefined rotational angle, to move the rollers automatically into the viewable positions.

A method for the register-true alignment of sheets ( ) before the transfer to a sheet-processing machine with the assistance of a carrier ( ) that is movable in the machine cycle and is driven as a function of a signal, in order to feed the sheets individually to an aligning stop. To permit exact and reliable alignment even at high machine speeds with an uncomplicated mechanism, the signal is generated when a sheet edge ( ) to be fed passes a predetermined location between the carrier ( ) and aligning stop ( ), and in response to the signal, the carrier performs a preset movement, identical from sheet to sheet, by which the carried-along sheet ( ) is fed to the aligning stop with a speed greater than zero, but substantially less than the maximum sheet speed during the feeding movement. The method is particularly suitable for side-edge alignment, but is also suitable for leading-edge alignment.
