| A viscosity control unit provides improved and efficient residual ink removal from an imaging member following the transfer of the majority of the ink from the imaging member to a substrate, and prior to the application of a subsequent ink application to the imaging member. The viscosity control unit hardens the residual ink on the imaging member to produce a hardened residual ink. By increasing the viscosity of the residual ink before it is removed by a cleaning station, the removal of the residual ink from the imaging member becomes easier and more efficient. | ||||||

| A printing apparatus applies ink to a surface of a printing plate in the shape of a predetermined pattern and then transfers the ink to a substrate. The printing apparatus includes: an image recording section that applies the ink to the surface of the printing plate; a plate surface observation unit that acquires information about the surface of the printing plate; a storage section that stores information about a reference shape serving as a reference of the surface of the printing plate; and a determination section that compares the information about the reference shape stored in the storage section with the information about the surface of the printing plate, which is obtained by the plate surface observation unit, and determines whether or not the surface of the printing plate to which the ink has been applied is present in a predetermined range of the reference shape. | ||||||

| An apparatus for cleaning surfaces of a printing press has an adjusting device having a pressing element for pressing a cleaning element against the surface to be cleaned when needed. The adjusting device has a drive for moving the pressing element relative to the surface to be cleaned between a home position, in which the cleaning element is positioned at a distance from the surface to be cleaned, and a cleaning position in which the cleaning element is in contact with the surface to be cleaned or, respectively, is in the direct proximity of the surface to be cleaned. An overload safety device is configured to respond upon a critical force acting on at least one of the adjusting device or pressing element being exceeded and to move the pressing element into an overload position. | ||||||

| This invention discloses a numbering and imprinting machine including a number cylinder, moving inker, first cleaning device, second cleaning device, inker position detector, and control device. The number cylinder includes at least one numbering device. The moving inker includes a number inker which supplies ink onto the number cylinder, and is movable between a printing position at which the number inker comes into contact with the number cylinder, and a retraction position at which the number inker separates from the number cylinder. The first cleaning device cleans the number cylinder. The second cleaning device cleans the number inker. The inker position detector detects the position of the moving inker. When the inker position detector detects that the moving inker is set at the printing position, the control device rotates the number cylinder, drives the number inker and controls cleaning operations by the first cleaning device and the second cleaning device. | ||||||

| A system and method are provided for depositing a release layer/film on a cleaner roller in an image forming device to facilitate effective cleaning of a reimageable surface in an image forming device using a proposed variable data digital lithographic image forming architecture. A borax or other solute solution is deposited on a surface of a cleaner roller and an air knife is used to evaporate a liquid component of the solution causing the liquid to come off and a thin-film of borax or other solute to remain on the surface of the cleaner roller. The thin film layer is then dry at a point of contact with the reimageable surface to recover residual ink from the reimageable surface with the surface of the cleaner roller on top of the thin film layer. The thin film layer is re-wetted to support efficient transfer of the ink to a web. | ||||||

| A method for successive printing of a first print job and a second print job on the same web using at least one printing group of the rotary press to print the first print job and the second print job is provided. The printing group includes at least a plate cylinder, a plate, a blanket cylinder and a blanket. Between the first print job and the second print job, a plate-changing stage occurs in which the blanket is held away from the web and the plates of the plate cylinder are changed. According to one aspect of the invention, between the first print job and the second print job, the web is kept traveling through the rotary press. | ||||||

| A system and method are provided for optimizing a multi-color variable digital data lithographic image forming system by controlling characteristics of one or more individual color inks to maximize ink transfer of a particular color ink layer onto the surface of an image receiving medium substrate, or onto other color ink layers deposited on the surface of the image receiving medium substrate when producing digital output images, including multi-color digital output images, with a proposed variable digital offset lithographic architecture. Ink characteristics and ink transfer parameters are particularly optimized in the proposed variable digital data lithographic systems to promote high efficiency ink transfer from an ink donor surface to an ink receiver surface in order that excessive amounts of untransferred ink do not remain on the ink donor surface requiring extensive cleaning of the reimageable surface in the image forming system between cycles of a multi-color ink system. | ||||||

| 180 | Cleaning Method for a Variable Data Lithography System | US13095778 | 2011-04-27 | US20120103221A1 | 2012-05-03 | Timothy Stowe; Eric Peeters; Martin Sheridan; Ashish Pattekar; Gregory Anderson |
| An cleaning method for a variable data lithography system employs a first cleaning member having a conformable adhesive surface disposed for physical contact with an imaging member such that residual ink remaining on the imaging member, such as following transfer of an inked latent image from the imaging member to a substrate, adheres to the conformable adhesive surface and is thereby removed from the imaging member. The cleaning method may further employ a second cleaning member, in physical contact with the first cleaning member, having a relatively hard, smooth surface such that residual ink removed from the imaging member and adhering to the adhesive surface of the first cleaning member may split onto the second cleaning member. | ||||||
