A method for deriving and implementing one or more motion profiles is provided. In the method, at least one time constraint between a first motor controlled system in an automated device and a second motor controlled system in the automated device are identified. Known parameters of the first motor controlled system and the second motor controlled system are identified and supplied. A first motion profile for the first motor controlled system is created. A second motion profile for the second motor controlled system is created. The identified at least one time constraint is applied to the first and second motion profiles to constrain the first and second motion profiles to one another. The first and second motion profiles are solved to complete a solution having solution information to prepare for use by said first and second motor controlled systems. The solution information is post-processed for use by the first and second motor controlled systems.

For manufacturing security documents, a plurality of security documents are printed on a sheet. The sheets are being processed in batches (15a, 15b). Each sheet carries a unique, machine readable identifier. During manufacturing, the batches are processed by several printing stations (10). At each printing station, the identifiers are read by a local computer (13) attributed to the printing station. The results are transferred upon request in data packets to a central data base (16). Each data packet contains the information for several sheets, which obviates the need to transfer the corresponding data in real time over the network. To increase security and decrease network dependence, each local computer is equipped with apparatus to check the processing status of a batch autonomously.

An image of a design pattern of wallpaper stored in a data base (DB) is viewed by a user computer of a user who is a general consumer or a contractor from a server computer provided in a head office of a wallpaper manufacturer through the Internet. Further, upon accepting an order of wallpaper from the user who saw the image by the user computer, the server computer fetches the image of the design pattern from the DB. A wallpaper printer then prints the image on a wallpaper sheet, thereby manufacturing the wallpaper desired by the user. The produced wallpaper is delivered to the user who gave out the order by, for example, a door-to-door delivery service.

A printer generates a public key with a passphrase containing at least printer position information, and holds the public key in a public key storage. When transmission of a public key is requested by a print client, the printer reads the public key from the public key storage and transmits the public key. The print clients transmits print transmitting data generated by encrypting print data with the previously acquired public key. The printer which has received the print transmitting data generates a private key with a passphrase containing at least printer position information. The printer decrypts the received print transmitting data with the private key.

In a method of monitoring a printing parameter of a printer, as well as a corresponding printing system, printing data are printed out, before being transmitted to a printer, by means of a further printer. The further printer is coupled to a sensor arrangement and monitored by means of a control unit, for determining desired values by using the printout produced by the further printer. By using this printout, a predetermined criterion is determined for a comparison of the printing parameter.

An image forming apparatus including an image forming device for forming an image on a sheet, a discharging device for discharging the sheet on which the image is formed by the image forming device, a containing portion for containing the sheet discharged from the discharging device, a sheet holding device capable of holding the sheet before the discharged sheet is contained in the containing portion, and a switching device for switching the holding of the sheet holding device for the sheet in response to an image forming method of the sheet.

A method for eliminating a rhythmic register error in a sheet-fed printing machine with a multiple-size sheet-conveying cylinder having at least one first and one second gripper device includes varying instants of closure of the gripper devices by adjusting adjusting devices assigned to the gripper devices so as to compensate for the register error; and a device for performing the foregoing method.
摘要:
A hammer-impactable and differentially indexible typebar comprising a plurality of type characters of variously dimensioned surface areas is provided with impact control means cooperable with the printing means of a calculating machine and effective for regulating the impacting force of the hammer thereof according to the surface area and location of the selected character to be printed, such regulation serving to assure that all character representations printed by the typebar in an alpha or numeric printer are of such uniform density as to permit satisfactory reading thereof by optical machine-reading equipment. The impact control means of the typebar serves to establish a variable clearance between the hammer and the differentially indexed typebar such that the predetermined firing flight of the hammer will impart a variable striking force of the typebar against a ribbon and a record medium interposed between the selected character and a printing platen.

An apparatus for producing proof prints on which the correctness of page impositions can be checked comprises a stand configured to receive a roll of paper. A first printer and a second printer are provided for printing pages on the front side and the rear side, respectively, of a paper web fed from the paper roll. An optical sensor is arranged between the first printer and the second printer. The optical sensor is configured to detect the position of an alignment mark which has been printed by the first printer on the front side of the paper. A control unit modifies the spatial relationship between the rear side of the paper and what is printed on the rear side of the paper depending on the detected position of the alignment mark. This can be accomplished either by electronically modifying the second pages as such, or by mechanically modifying the paper position with respect to a printing head contained in the second printer.
摘要:
The supply of a negative pressure to an opening P(+1) adjacent to an opening P(0) is stopped by switching a suction valve connected to the opening P(+1) from an open state to a closed state while keeping a positive pressure valve connected thereto closed. Then, near the opening P(+1), a force for holding a blanket becomes gradually weaker against a pressure force in a pressurized space. Associated with that, an air component in the pressurized space flows into a space between a portion of the blanket vertically above the opening P(+1) and an upper surface, whereby the blanket portion is lifted from the upper surface and brought into contact with the lower surface of a printing plate. In this way, a contact area is slowly and stably widened while a sudden change of a pressure in the pressurized space SP5 is suppressed.
