    Abstract: A sheet-fed printing unit has a first impression cylinder and a second impression cylinder, which are arranged directly and interactingly in contact and which each have an axis of rotation. An axial plane contains the axes of rotation. A reference plane is a plane which contains an axis of rotation of a cylinder of this type and has a horizontal surface normal. These two cylinders are arranged such that an intersection angle between the axial plane and the reference plane is a maximum of 15°. A transport path is provided for a transportation of sheets, which transport path has a region for the respective impression cylinder in which there is contact between sheets and a casing surface. This region of the transport path for the respective impression cylinder extends over an angular range of at least 270°. A sheet-fed printing machine has a sheet-fed printing unit of this type.

  • Patent number: 10576750
    Abstract: A method for compensating for disruption torques in driving a jetting cylinder in an inkjet printing machine includes recording print image products for at least one color and at least one complete rotation of the jetting cylinder by using an image sensor and using a computer for a time parallel measurement of a driving torque of the jetting cylinder, generating an average gray value profile above a circumferential coordinate based on the recorded image data by using the computer, transforming the average gray value profile and the measured profile of the driving torque into a frequency range by using a computer-assisted Fourier transform and extracting order components from the frequency range. A periodic compensation torque is calculated based on the extracted order components, and the calculated periodic compensation torque is factored-in when actuating the jetting cylinder of the inkjet printing machine in the course of a printing operation.

  • Patent number: 8840745
    Abstract: A method of printing foil images upon textiles is provided. Advantageously, a digital inkjet printer can be utilized to apply an adhesive for affixing a foil embellishment. The method of printing foil images upon textiles includes applying a pretreatment solution upon a textile. After the pretreatment solution has dried, a white underbase in the form of a fanciful design is printed upon the textile using a digital inkjet printer. A heavy color layer of color ink is then digitally inkjet printed upon the white underbase. Thereafter, the textile is removed from the inkjet printer and positioned upon a heat press table. Foil transfer paper is positioned upon the textile so as to cover the white underbase and heavy color layer. The heat press is activated so as to adhere the foil, but only to those regions where the white underbase and color ink has been printed. Once cool to the touch, the foil is slowly peeled from the textile so as to leave a fanciful foil design.

    Abstract: A method for printing and decorating packaging materials, such as paper, paper board and various flexible polymer films by electron beam exposure of plural layers of curable inks and coatings which do not substantially change viscosity during the printing process. The inks and coating are essentially free of volatile components such as organic solvents, inorganic solvents, water and low molecular weight fractions before, during and after exposure to electron beam irradiation. The method involves applying multiple layers of ink and an optional coating onto a substrate. The ink is an admixture of a colorant, and an unsaturated component such that the inks have a maximum of 10% volatile components. Thereafter these layers are simultaneously exposed with electron beam radiation to cause the ethylenically unsaturated components to polymerize or crosslink such that they become dried.

  • Patent number: 7240613
    Abstract: A method for driving a satellite offset press, and a satellite offset press which, with little expenditure, permits multicolor printing in one pass. A satellite offset press, in which form cylinders and associated transfer cylinders are driven synchronously, while in each case segments located in the circumferential direction of the form cylinders and of the transfer cylinders and also of the transfer cylinders and of an impression cylinder interacting with the latter roll on one another in accurate register with a sheet held thereon, following each full revolution. The speed of the impression cylinder is reduced and increased again, so that the transfer cylinders lead by at least one segment length in the circumferential direction.

  • Patent number: 7096782
    Abstract: A driving apparatus in a printing press includes a plate cylinder driven by a printing press motor, an inking device drive-coupled to the plate cylinder, and a driving connecting/disconnecting mechanism. The mechanism connects and disconnects transmission of driving from the plate cylinder to the inking device, and includes first and second gears which are engageable with each other, supported rotatably, and constantly drive-coupled to one and the remaining one, respectively, of the plate cylinder and inking device. The second gear has a second engaging portion engageable with a plurality of first engaging portions of the first gear which have the same shape and are equidistantly arranged in a rotational direction of the first gear. When the first and second engaging portions engage, the plate cylinder and inking device are drive-coupled; when they are disengaged, they are disconnected.

  • Patent number: 6868781
    Abstract: A printing press performs offset color printing. A blanket cylinder having four image segments selectively contacts a plate cylinder having four image segments and an impression cylinder having five image segments for carrying print media. A pair of eccentric bushings for independently controlling the impression cylinder engages same to blanket cylinder. A print media feed system and a delivery system are located on the same side of the press and cooperate with each other via a means for moving feed and delivery trays in a generally vertical direction. Print media are gripped only once and travel in the same direction until let go by the impression cylinder. An image forming system forms four images on a plate cylinder to be inked by four respective inking units oriented therearound. All four plate image sections can be inked during one rotation of the plate cylinder. Four inking units including a minimal number of rollers for inking the plate image sections.
