Patent number: 8449067Abstract: A method for operating an inkjet printing device with at least one inkjet printhead having a row of nozzles through which ink can be directed onto the substrate to be printed, which is guided over a cylinder or over a curved guide element. The inkjet printhead or each inkjet printhead is oriented transversely to the transport direction of the substrate, so that the nozzles in the row of the inkjet printhead or of each inkjet printhead are different distances away from the substrate to be printed. To print the substrate, the nozzles in the nozzle row of the inkjet printhead or of each inkjet printhead are actuated in such a way that that the differences in the nozzle to substrate travel time caused by the different distances between the nozzles in each row and the substrate to be printed are equalized or compensated.Type: GrantFiled: December 15, 2006Date of Patent: May 28, 2013Assignee: MAN Roland Druckmaschinen AGInventor: Peter Schulmeister

Patent number: 8181556Abstract: To control the cutting register of a web in a web-fed rotary press with little expenditure, a specific item of image information or a measuring mark of a printed web is registered by at least one sensor. The sensor generates a registration signal which is supplied to a control device. The registration of the image information or measuring marks is carried out immediately before or on a knife cylinder. A cutting register error is determined from the registration information and the position of the knife cylinder is influenced to correct the determined cutting register error.Type: GrantFiled: December 10, 2007Date of Patent: May 22, 2012Assignee: MAN Roland Druckmaschinen AGInventors: Günther Brandenburg, Stefan Geissenberger, Andreas Klemm
