Patent number: 10252552Abstract: A method for printing at least one section of a flat or preferably curved surface of an object includes using a relative movement between an inkjet head and the object to move the inkjet head along a first path and print a first track in the process and to move the inkjet head along a second path and print a second track in the process. A first track edge of the first track and a second track edge of the second track meet at a point and enclose an angle between about 1° and about 179° at the point. The method permits the curved surface to be printed without perceptible track connections.Type: GrantFiled: June 1, 2017Date of Patent: April 9, 2019Assignee: Heidelberger Druckmaschinen AGInventors: Heiner Pitz, Matthias Schloerholz

Patent number: 9943888Abstract: A method for removing solidified ink or varnish from a surface includes applying a cleaning agent to the ink on the surface. The cleaning agent applied to the ink on the surface is substantially solvent-free and water-based and reduces adhesion between the ink and the surface without dissolving the ink. An adhesive side or face of a single-sided or single face adhesive element is applied to the surface. As the adhesive element is removed from the surface, the ink that has been treated with the cleaning agent but is undissolved adheres to the adhesive element and is thus removed from the surface together with the adhesive element without splitting.Type: GrantFiled: March 27, 2015Date of Patent: April 17, 2018Assignee: Heidelberger Druckmashinen AGInventors: Silvia Worgt, Jessica Gioia, Matthias Schloerholz, Heiner Pitz

Patent number: 9937734Abstract: A method for the indirect application of printing liquid onto a printing material provides an intermediate carrier, preferably a circulating belt, a liquid conditioning medium including a first substance applied onto the intermediate carrier and a printing liquid, in particular an inkjet ink, including a second substance applied onto the conditioning medium on the intermediate carrier. The printing liquid is situated as droplets or a layer substantially on the conditioning medium and the droplets or the layer form a contact region on their underside with the conditioning medium. The printing liquid is heated, preferably by way of a dryer and the printing liquid is transferred from the intermediate carrier onto the printing material.Type: GrantFiled: February 18, 2016Date of Patent: April 10, 2018Assignee: Heidelberger Druckmaschinen AGInventors: Bernard Beier, Martin Greive, Peter Hachmann, Axel Hauck, Rolf Kuendgen, Albert Maul, Rolf Mueller, Heiner Pitz, Achim Scheurer, Matthias Schloerholz, Michael Schwandt

Method for printing an object having at least one non-planar, contoured or three-dimensional surface
Patent number: 9266353Abstract: A method prints an object, for example a vehicle and specifically the body thereof, wherein at least one area of the surface of the object is printed. The method includes: providing an image; three-dimensionally measuring at least the area; generating a number of spatial points in correspondence with the area; generating a three-dimensional net corresponding with the area; generating path data, i.e. a three-dimensional path for moving a robot for an inkjet printer head; generating raster data, i.e. a raster matrix, in particular a three-dimensional or higher raster matrix, for actuating the inkjet printer head; moving the robot, for example an articulated arm robot, utilizing the path data; and printing the image by the inkjet printer head utilizing the raster data. The method permits multi-color printing of any image onto so-called 3D surfaces of any shape.Type: GrantFiled: September 24, 2014Date of Patent: February 23, 2016Assignee: Heidelberger Druckmaschinen AGInventors: Bernard Beier, Heiner Pitz, Matthias Schloerholz, Thomas Wolf -

Patent number: 8981254Abstract: In a method for re-imaging a printing form that has been used for printing in a prior printing process a substrate of the printing form is cleaned globally of ink or varnish and the substrate is treated abrasively globally in order to erase a preceding printing image. The substrate to be imaged with a new printing image is treated locally in image regions with a pulsed laser beam and, in the process, a nanoscopic and hydrophobic surface structure is produced locally. The substrate is treated globally with a hydrophilicity intensifier, as a result of which the substrate becomes hydrophilic locally in the previously hydrophobic image regions. An apparatus has a corresponding erasing unit and an imaging unit with a femtosecond laser.Type: GrantFiled: July 28, 2011Date of Patent: March 17, 2015Assignee: Heidelberger Druckmaschinen AGInventors: Heiner Pitz, Bernhard Mechler, Rolf Spilger

Patent number: 8882242Abstract: A system for printing an image, preferably a multicolor halftone image, onto at least one non-planar area of a surface of an object, for example a section of a body of a vehicle, includes an inkjet print head having nozzles, a robot, preferably an articulated robot, creating a primary movement, the primary movement including at least two printing paths of the inkjet print head being lateral to each other, and a device creating a secondary movement, the secondary movement being substantially perpendicular to the primary movement and causing the printing paths to laterally adjoin each other. As a result, undesired streaks between the printing paths may advantageously be reduced or prevented.Type: GrantFiled: March 29, 2013Date of Patent: November 11, 2014Assignee: Heidelberger Druckmaschinen AGInventors: Bernard Beier, Uwe Ernst, Helge Grandt, Heiner Pitz
