Patent number: 11697293Abstract: Disclosed is a printing apparatus in which web paper is transported to a printing face contact roller in a swirling form while a direction thereof is turned by first to fourth turning rollers. Heating units are arranged so as to face a printing face of the web paper between the two first and second turning rollers, between the two third and fourth turning rollers, and between the fourth turning roller and the printing face contact roller individually. Such arrangement can achieve a compact drying mechanism. The heating units each directly heat inks on the printing face, and thus do not overheat the web paper. Moreover, the heating units are not directed upward. This avoids contact of the web paper to a front side face of each of the heating units when the web paper slackens.Type: GrantFiled: July 28, 2021Date of Patent: July 11, 2023Assignee: SCREEN HOLDINGS CO., LTD.Inventors: Yuki Tsutsui, Mitsuru Tanemoto, Takahiro Uda, Masaki Era

Publication number: 20110252992Abstract: A method for operating a web printing system enables web and roller changes arising from temperature changes to be identified and used to adjust operation of the reflex registration system. The method includes identifying a temperature change for at least one roller in a web printing system, identifying a temperature change for a web moving through the web printing system at one or more locations in the web printing system, modifying web velocity computations for a reflex registration system with reference to the identified temperature change for the at least one roller and the identified temperature change for the web, and operating printheads to eject ink onto the web at positions identified with reference to the modified web velocity computations.Type: ApplicationFiled: April 16, 2010Publication date: October 20, 2011Applicant: XEROX CORPORATIONInventors: R. Enrique Viturro, Yongsoon Eun, Todd Thayer, Jeffrey J. Folkins

Publication number: 20110247508Abstract: The invention refers to a flexographic printing process with wet on wet capability based on controlled polymer or polymer segment precipitation that leads to gel formation of ink compounds by controlling the solubility parameter of the ink system. The mechanism to obtain a desirable wet on wet color trapping is the formation and/or presence of a gel in the applied ink film due to a controlled physicochemical mechanism of resin precipitation. This is accomplished either by controlling a change in the Hansen Solubility Parameter of the liquid in the ink through evaporation of some or all of a non-reactive and volatile solvent, or alternatively by use of a polymer comprised of two distinct and separate segments one of which is soluble in the monomer/oligomer mix and the other of which is not.Type: ApplicationFiled: June 21, 2011Publication date: October 13, 2011Inventors: Valter Marques BAPTISTA, Wilson Andrade Paduan

Patent number: 8033220Abstract: A method of printing onto closed vial units. The vial units are formed in a series and the vial units have a drug therein. The method involves providing the series of vial units onto a conveyor belt; positioning the vial units adjacent cleats on the conveyor belt; engaging a first offset inking transfer device on a fist side of said vial units; engaging a first back-up roller against said vial units, said first back-up roller being placed opposite said first offset inking transfer device; capturing the vial units between said first back-up roller and said first offset inking transfer device; printing onto the vial units with said first offset inking transfer device; and curing the ink with a first ultra violet dryer.Type: GrantFiled: December 5, 2009Date of Patent: October 11, 2011Inventor: Kent Byron

Publication number: 20110239878Abstract: An object of the invention to provide a screen printing machine allows, during maintenance work for one printing device, the other printing device to continue its screen printing work, and a method for controlling an inside temperature of a screen printing machine. A space surrounded by a base (12) and a cover member (11) is divided into two portions by a partition member (14), and two printing devices (13) are accommodated in two working compartments (15), respectively, which are defined by the base (12), the cover member (11) and the partition member (14), whereby temperature-controlled air is blown into each of the working compartments (15) via an air pipe (71) which branches into two air vents (72) opened to the respective working compartments (15).Type: ApplicationFiled: October 23, 2009Publication date: October 6, 2011Applicant: PANASONIC CORPORATIONInventors: Seiichi Miyahara, Kimiyuki Yamasaki, Minoru Murakami, Takahiro Fukagawa, Takashi Yazawa, Nobuhiro Nakai

Publication number: 20110128680Abstract: Design and integration of a UV LED curing system into a multi-station UV-curing process, such as for inkjet or offset printing. Docking ports may be permanently mounted into various stations within the UV-curing process. The UV LED lamps may be modular and may therefore be inserted into any one of the desired docking ports at variable distances from the substrate to be cured without significant loss of optical uniformity or radiant intensity. The docking ports are designed such that they can accommodate UV LED lamps of differing wavelengths and, therefore, power requirements. The insertion of a UV LED lamp into a docking port is designed such that it is accomplished without tools and may be considered a “plug and play” operation. Multiple docking ports may be mounted into a single station in the UV-curing process to allow for the installation of multiple lamps at each station.Type: ApplicationFiled: August 26, 2010Publication date: June 2, 2011Inventors: Aaron D. MARTINEZ, Stephen J. METCALF

Patent number: 7913622Abstract: A method for drying a printing ink (114) on a printing substrate (14) in a printing press (30), and a printing press (30). The printing substrate (14) is moved along a path (16) through the printing press (30) and printed on by at least one printing ink (114) at a first position (18) of the path (16). At a second position (124) of the path (16), in a conditioning apparatus, a treatment agent (118) is applied to the printing substrate (14) to accelerate the drying of the printing ink (114) on the printing substrate (14) and includes, in particular, an infrared absorber which has an absorption wavelength that is essentially resonant to the wavelength of the light (12) of the radiant energy source (10). The printing substrate (14) may be dried by the action of radiant energy at a chronologically later point in time, at at least one third position (116) of the path (16), by a drying device, in particular by a narrow-band radiant energy source (10).Type: GrantFiled: August 4, 2008Date of Patent: March 29, 2011Assignee: Heidelberger Druckmaschinen AGInventors: Heiner Pitz, Axel Hauck, Werner Anweiler, Peter Hachmann

Publication number: 20100319559Abstract: At least one rotating component of at least one printing unit is regulated to a target value for a temperature, representing the component temperature, by a temperature controller. At least one drive of an assembly of the printing machine is regulated or controlled, on the basis of a target value for a rotational speed prescribed by a command level, with respect to a rotational speed to be maintained. For at least an operating phase transient, relative to the rotational speed, a target value prescribed by the command level, is modified. This is done by considering at least one member of a route and/or a control model characterizing the temperature controller and/or by using a rule (F2(?)) for a dependence of a rotational speed on a temperature. The modified target rotational speed serves as a prescribed value for the rotational speed of the drives.Type: ApplicationFiled: October 8, 2008Publication date: December 23, 2010Inventors: Klaus Georg Matthias Müller, Günther Ewald Gabriel
