Patent number: 11565516Abstract: According to aspects of the embodiments, there is provided a method of measuring the amount of fountain solution employed in a digital offset lithography printing system. Fountain solution thickness is measured by using phase shifted monochromic light to produce optical path differences through the fountain solution film. The intensity of the reflected light through the fountain solution film is very sensitive due to the phase shifted light so interference fringes are easier to delineate and fountain solution thickness measurement more reliable.Type: GrantFiled: December 30, 2020Date of Patent: January 31, 2023Assignee: Xerox CorporationInventors: Paul J.

Publication number: 20080196610Abstract: A device for adjusting the position of a printing unit with respect to a printing web in a rotary printing machine comprising a control unit operable for controlling the movement of the printing unit from a predefined initial position Pi to a predefined end position Pf by successive steps T. A vision system is operable for capturing images of the formats (F) which are successively printed on the printing web between the initial position Pi and the end position Pf. A calculation unit is operable for evaluating the images and for determining the position Popt of the printing unit at which the images are identical and additionally the position at which the grayscale of the pixels of each image are identical.Type: ApplicationFiled: February 21, 2008Publication date: August 21, 2008Inventors: Roger ROCH, Benoit ROSSET

Publication number: 20080173195Abstract: An offset printing press is provided, including at least one unit for printing a web of paper, a device for transversely cutting the web of paper arranged downstream of the printing unit, and at least one system for controlling the printing unit. The control system is suitable for controlling, when the web of paper is moving, the implementation of steps involving: a) moving the printing unit into a throw-off configuration, the web of paper moving in the space delimited between the blanket cylinders, b) slowing down or accelerating the plate cylinder in order to modify the adjustment of the cutting register between the printing unit and the cutting device, c) moving the printing unit into a throw-on configuration.Type: ApplicationFiled: December 20, 2007Publication date: July 24, 2008Applicant: GOSS INTERNATIONAL MONTATAIRE SAInventors: Francois Vidaillac, Jean-Philippe Lecomte

Publication number: 20080160450Abstract: A method for treating a re-imageable printing form includes surface modifying a surface of the printing form acting as a printing area in a nanoscopic range by chemically functionalizing the surface through covering with molecules, in particular amphiphilic molecules or polymers. The printing form is subjected to a primary process of imaging by laser radiation, and subjected to a primary process of application of at least one lithographic fluid, for example dampening solution, printing ink and/or varnish. The molecules are fixed in image regions by the primary process of imaging. The molecules are removed in non-image regions substantially by at least one primary process different than the application of printing ink, in particular by imaging, application of dampening solution or chemical developing. An apparatus for treating a re-imageable printing form, a machine for processing printing material and a method for treating a surface contacting printing material, are also provided.Type: ApplicationFiled: December 19, 2007Publication date: July 3, 2008Applicant: HEIDELBERGER DRUCKMASCHINEN AGInventors: Matthias Schlorholz, Martin Gutfleisch, Harald Latzel, Michaela Hoffmann, Gerald Erik Hauptmann, Uwe Tessmann

Patent number: 7377216Abstract: The invention relates to a variable printing machine which is embodied in the form of at least two offset printing apparatus (1) and comprises a frame bearing an opposite cylinder against which a blanket (11) to be printed is pressed by a blanket drum. Printing ink is supplied to a printing cylinder which contacts the blanket drum by means of inking rollers. The inventive printing machine is characterized in the following: the opposite cylinder of each apparatus (1) is devoid of all rotatable transmissions; a levelling between two adjacent units which print one and the same blanket face (11) is embodied in such a way that said blanket is in contact with the blanket drums only.Type: GrantFiled: July 31, 2003Date of Patent: May 27, 2008Assignee: Komori-Chambon S.A.Inventors: Pierre Simon, Bernard Six

Patent number: RE41048Abstract: A combined lithographic/flexographic printing process having a plurality of successive printing stations for printing color images on a substrate in a continuous in-line process. One of the stations prints a first color image using the flexographic process and at least one of the successive printing stations prints a second color image over the first color image using an offset lithographic process in the continuous in-line process.Type: GrantFiled: May 20, 1999Date of Patent: December 22, 2009Assignee: Williamson Printing CorporationInventors: Bill L.
