摘要： Disclosed is a corrugated paperboard printer comprising a pressing device for applying a pressing force to press a chamber which reserves ink toward an anilox roll. The pressing device is configured to apply a first pressing force, and a second pressing force which is greater than the first pressing force, respectively, to a first pressing area and a second pressing area in a back surface of a chamber frame. In a state in which no pressing force is applied by the pressing device, bending occurring in the chamber frame due to a load transmitted from a printing roll to the chamber frame via the anilox roll as printing is performed to a corrugated paperboard sheet is greater in the second pressing area than in the first pressing area.

摘要： A processing machine, in particular a printing machine, includes a unit having a storage container. The storage container comprises a roller and a base which delimit the storage chamber for a medium. One or more sliders are arranged along the edge of the base to form, together with the roller, an outlet gap for the medium. In the region of the one or more sliders, pneumatic means are provided to seal the supply chamber with respect to the medium. A method for operating such a processing machine is also disclosed.

摘要： In a digital inking system having an anilox member that carries a patterned metered layer of ink to a digital imaging member, and a doctor blade that removes excess ink from the surface of the anilox member resulting in the patterned metered layer, an overfill form roller in rolling contact with the anilox member adds an overcoat layer of ink on the patterned metered layer for transfer of both layers of ink to the digital imaging member. The overcoat layer of ink uniformly covers all regions of the anilox member and the mattered metered layer of ink, including lands of the anilox cell walls to make the combined layers of ink pattern-free.

摘要： Correction values (Δθ1-Δθn) according to image area ratios in ranges of a printing plate of a preceding print job corresponding to ink fountain keys (4-1-4-n) are obtained. Opening amounts (θ1b-θnb) of the ink fountain keys (4-1-4-n) corresponding to the image of the printing plate (7′) of a next print job are corrected by correction values (Δθ1-Δθn) to obtain corrected opening amounts (θ1b′-θnb′). In a state in which ink in an ink roller group (6) has been decreased by scraping and removing it by an ink scraper blade (15) and in a state in which the opening amounts of the ink fountain keys (4-1-4-n ) have been set to the corrected opening amounts (θ1b′-θnb′), an ink film thickness distribution corresponding to the image of the printing plate of the next print job is formed on the ink roller group (6).

摘要： A fluid distribution device, for applying a fluid onto a transfer roller, comprises includes an elongated chamber, at least one inlet for letting a fluid into the chamber, a longitudinal opening extending in the axial direction and adapted to face a transfer roller to allow fluid to exit the chamber and contact the transfer roller, and at least one wiper blade extending along at least a portion of the longitudinal opening. The chamber includes, at each of the two axial ends of the chamber, a wall separating the chamber from a cavity. The wall has a wall surface arranged to face the transfer roller when the device is in use. The wall is dimensioned so that the wall surface will be distanced from the transfer roller when the device is in use, so as to allow fluid to be present in a gap between the wall surface and the transfer roller.

摘要： A printing press includes a plurality of inkers. Each inker prints a different color ink. The press includes a first module, a second module, a roller and a support member. The first module has motors to drive output shafts. The second module has ink displacement units, an ink inlet to provide ink to the ink displacement units, ink channels to transfer ink from the ink displacement units to ink outlets of the second module and input shafts to removably couple to the output shafts of the first module. The roller receives ink from the ink displacement units and transfers the ink toward a substrate. The support member supports the first and second modules in at least one position relative to the roller. The support member facilitates removal of the second module.

摘要： Systems and methods for providing remote approval of an image for printing are provided. One system includes a processing circuit in communication with an image capturing device that is configured to capture an image of a printed product. The processing circuit is configured to process the captured image into a processed image accurate to within a tolerance in a color space to indicate the visual appearance of one or more colors. The color space is a standardized color space, such as sRGB or CIELAB. The processing circuit is further configured to transmit the processed image to a display located remote from the image capturing device and to receive an input signal from a remote input device to allow a user to approve or reject the displayed processed image for printing on a print device.

摘要： After the end of a preceding print job, a printing press is stopped, and ink form rollers (6-1 to 6-4) of an ink roller group (6) are thrown off. After that, a printing plate (7) is exchanged with a printing plate (7′) of a next print job, and a blanket (91) mounted on a blanket cylinder (9) is cleaned. The opening amounts of ink fountain keys (4-1 to 4-n) corresponding to the image of the printing plate (7′) of the next print job are obtained. The obtained opening amounts of the ink fountain keys (4-1 to 4-n) are corrected by correction values of the opening amounts of the ink fountain keys (4-1 to 4-n) considering the influence of cleaning of the blanket (91) to obtain corrected opening amounts. In a state in which the opening amounts of the ink fountain keys (4-1 to 4-n) have been set to the corrected opening amounts, a corrected ink film thickness distribution corresponding to the image of the printing plate (7′) of the next print job is formed on the ink roller group (6).
