摘要： A printing press cleaning device includes a solvent supply nozzle (34) configured to supply a solvent containing a surfactant to an ink roller group (21) that includes a plurality of ink rollers configured to receive ink from an ink fountain (18a) and send the ink to a plate cylinder (17). The cleaning device includes a first or second cleaning solution supply nozzle (35, 36) configured to supply a first or second cleaning solution containing a volatile organic solvent to the ink roller group (21). The cleaning device includes a doctor blade (33) configured such that a distal end thereof can come into contact with and be moved away from an ink roller of the plurality of ink rollers, and scrape and collect the ink, the solvent, and the first or second cleaning solution of the ink roller group (21) at a contact position of the distal end that comes into contact with the ink roller. It is possible to provide a printing press cleaning device capable of shortening a cleaning time and improving an operation efficiency by efficient cleaning without increasing the supply amount of the cleaning solution.

摘要： Provided is a method for automatically adjusting the contact pressure between an intaglio cylinder and a wiping roller that further limits the amount of defective prints generated. The method adjusts said contact pressure by changing the position of the wiping roller shaft center with respect to the intaglio cylinder shaft center using a contact pressure adjustment motor. At least the position of the wiping roller shaft center at low speed and the position of the wiping roller shaft center during printing operation for which the contact pressures have been optimized during a previous printing are stored. Before starting the current printing operation, the wiping roller is moved to the stored low speed position. Then when the current printing operation is started, the wiping roller is moved to the stored printing operation position.

摘要： Correction values (”¸1 - ”¸n) 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 (¸1b - ¸nb) 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 (”¸1 - ”¸n) to obtain corrected opening amounts (¸1b' - ¸nb'). 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 (¸1b' - ¸nb'), 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： The purpose of the present invention is to provide a combination printer that makes it possible to perform both offset printing and Orlof printing on a single printer, and for offset printing, allows the selection of either double-sided or single-sided printing. An Orlof printing section (2) is provided with an Orlof printing unit that has the following: partial plate cylinders (11), a collecting blanket cylinder (12), a collecting plate cylinder (13), a blanket cylinder (9), an impression cylinder (10), and a moving inker (25). An offset printing section (3) is provided with front-side and back-side offset printing units (3a-3d, 3e-3h) that each have an ink-supply device (18), a plate cylinder (19), a blanket cylinder (15), and an impression cylinder (16) . The respective impression cylinders of the front-side offset printing unit and the back-side offset printing unit are placed up against each other such that said printing units receive and output sheets between said impression cylinders. The offset printing section (3) is also provided with a front-side inspection camera (23) and a back-side inspection camera (24). The Orlof printing section and the offset printing section are connected by transfer cylinders (14).

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).
