20100236432 | Process for Producing Security Papers, Intaglio Printing Press for Implementing Said Process, and Security Paper Produced According to Said Process - There is described process for producing security papers, in particular banknotes, comprising the step of sealing the surface of the security papers by applying a protective pattern on the surface of the security paper, which sealing comprising printing the security papers by intaglio printing using an intaglio printing plate with engraved areas such that at least 80% of the whole surface of each security paper is covered with embossed intaglio patterns produced by engraved areas of the intaglio printing plate which are inked or with a combination of embossed intaglio patterns and flat intaglio patterns, which flat intaglio patterns are produced by unengraved areas of the intaglio printing plate which are inked after wiping of the intaglio printing plate, at least a part of the embossed intaglio patterns and/or flat intaglio patterns being printed with a transparent or semi-transparent intaglio ink. The transparent or semi-transparent intaglio ink is applied in engraved areas and/or unengraved areas of the intaglio printing plate so as to seal substantially the whole surface of the security papers with a protective pattern composed of intaglio patterns. Also described are intaglio printing presses for implementing the said process and the resulting security papers. | 09-23-2010 |
20110192298 | DRIVE CONTROL METHOD AND DRIVE CONTROL APPARATUS FOR PRINTING PRESS - According to a drive control method and apparatus, an offset printing section and an intaglio printing section are connected together by a gear train. Separately from an offset printing section prime motor for driving an entire sheet-fed printing press, an intaglio printing section auxiliary motor is provided in the intaglio printing section where load is heaviest and load variations are great. By so doing, the entire sheet-fed printing press is driven by the offset printing section prime motor and the intaglio printing section auxiliary motor. Moreover, the electric current value (driving torque value) of the intaglio printing section auxiliary motor is controlled in accordance with an electric current value (torque value) for driving the offset printing section prime motor, the torque distribution rate of the intaglio printing section auxiliary motor, and the rated electric current value of the intaglio printing section auxiliary motor. | 08-11-2011 |
20130042773 | WIPING DEVICE - A wiping device includes an intaglio cylinder, a cylinder cleaning device, and a wiping liquid supply device. The intaglio cylinder is rotatably supported. The cylinder cleaning device removes excess ink adhered to an outer surface of the intaglio cylinder. The wiping liquid supply device supplies a wiping liquid for cleaning to the cylinder cleaning device. The wiping liquid supply device includes a waste liquid tank, a new liquid tank, a first pump, and second pump. The waste liquid tank stores a waste wiping liquid discharged from the cylinder cleaning device. The new liquid tank stores a clean wiping liquid. The first pump supplies the clean wiping liquid from the new liquid tank to the cylinder cleaning device. The second pump supplies a supernatant liquid of the waste wiping liquid stored in the waste liquid tank and separated into a precipitate and the supernatant liquid to the cylinder cleaning device. | 02-21-2013 |

The ink liner frame is removably attachable to an ink liner. A pad printing system includes a doctor blade, an ink liner, and an ink liner frame removably attached to the doctor blade, wherein the ink liner frame is removably attachable to the ink liner. | 09-18-2008 |
20080245246 | Apparatus For Coating a Cylinder, in Particular a Wiping Cylinder of an Intaglio Printing Press - There is described an apparatus ( | 10-09-2008 |
20090101028 | DOCTOR BLADE ASSEMBLY - Doctor blade assembly for rotogravure printing units, having a support structure for a doctor blade, a holding device of the support structure and a moving device for moving the holding device. The holding device includes a mounting suitable to fix either a chambered doctor blade or a non-chambered doctor blade to the moving device. | 04-23-2009 |
20090139415 | INTAGLIO PRINTING PRESS - An intaglio printing press includes an intaglio cylinder supported rotatably, an inking device for supplying ink to the intaglio cylinder, a wiping device for removing a surplus ink of the ink supplied to the intaglio cylinder, and a prewiping device, provided upstream of the wiping device and downstream of the inking device in the direction of rotation of the intaglio cylinder, for removing the ink before being removed by the wiping device. The prewiping device has a belt conveyor device for discharging the removed ink to the outside of the printing press. | 06-04-2009 |
20090266249 | Intaglio Plate Wiping System - An intaglio plate wiping system includes a wiping member which forms a nip with the intaglio plate in use and onto which excess intaglio ink is transferred during relative movement between the wiping member and the intaglio plate. A heated doctor blade unit is located downstream of the nip and cooperates with the wiping member to remove intaglio ink from the wiping member. A heated ink collecting container is provided into which ink removed from the wiping member passes. | 10-29-2009 |
