摘要： A printing apparatus includes a printing cylinder (14) that can hold sheets (4) and transfer them one by one continuously, first to fourth inkjet heads (41-44), and a feeder unit (2). The printing apparatus includes a speed reducer (72) that switches the speed of the feeder unit (2) between single-sided printing and double-sided printing. In single-sided printing, the feeder unit (2) is driven at a first supply speed at which the sheets (4) are supplied to the printing cylinder (14) one by one continuously, and the printing cylinder (14) is driven at a transfer speed at which the sheets (4) supplied from the feeder unit (2) one by one continuously are transferred. In double-sided printing, the printing cylinder (14) is driven at the transfer speed, and the feeder unit (2) is driven at a second supply speed that is ½ the first supply speed. The printing apparatus that operates stably in both single-sided printing and double-sided printing can be provided.

摘要： The present invention relates to a print quality inspection apparatus comprising: an illuminator (35 or 35A-35C) for irradiating light onto a printout (1) provided with a motion thread (1b); a camera (34 or 34A) for capturing an image of the printout; and a print quality inspection unit (10) for inspecting the print quality of the printout (1) on the basis of image data captured by the camera (34 or 34A). The camera (34) captures images of printouts (1) for each RGB color, and the print quality inspection unit (10) performs a print quality inspection having a scope that includes the motion thread (1b) on the basis of image data of a color of the same hue as the color of the motion thread (1b), or the illuminator (35A-35C) emits a color of the same hue as the color of the motion thread (1b), and the monochrome camera (34A) captures a monochrome image.

摘要： A print quality examination device is provided in a printing machine (1) provided with a printing unit (3) that performs printing on a mirror-reflection member (5a) of a sheet (5) to which the mirror-reflection member (5a) is added. The print quality examination device of the printing machine is provided with an examination camera (18a) that images a picture printed on the sheet (5), a light source (18h) that irradiates the sheet (5) with light, and a print quality examination unit (18g) that examines the quality of the picture printed by the printing unit (3) based on image data imaged by the examination camera (18a). The examination camera (18a) or the light source (18h) is configured to be movably supported on an arc about a detection point (P) imaged by the examination camera (18a) for the sheet (5).

摘要： This invention discloses an offset printing press for printing securities, which includes an offset printing unit, inspection camera unit, and sheet quality determination unit. The offset printing unit prints a ground tint pattern on a transported paper sheet. The inspection camera unit is arranged upstream of the offset printing unit in the direction in which the paper sheet is transported, and captures an image of the paper sheet. The sheet quality determination unit determines the quality of the paper sheet based on image data output from the inspection camera unit.

摘要： The present invention is a method for measuring the varnish film thickness of a printed article by obtaining the film thickness of varnish on a sheet (1) on which a pattern is printed on a base thereof with ink and the pattern is coated with the varnish, wherein a metal foil (1c) having a smooth surface is attached to the base of the sheet (1), and the film thickness of the varnish coated directly over the metal foil (1c) is detected with a spectral interference-type film thickness meter (81) so as to determine whether the film thickness of the varnish is acceptable or not on the basis of the results detected by the spectral interference-type film thickness meter (81).

摘要： A register error amount detection apparatus obtains the register error amounts between the colors of patterns printed on a printing product based on the positions of register marks in a captured image of the printing product. The register marks have different colors including a reference color and are printed in a line at intervals a in the vertical direction. The register marks all have the reference color and are printed in a line at the intervals a in the vertical direction at positions translated from the positions of the register marks by a distance b in the horizontal direction.

摘要： A digital printing press including a printing cylinder configured to transport a sheet, a driving device (41) configured to drive the printing cylinder, an encoder (44) configured to detect the phase of the printing cylinder, and first to fourth inkjet nozzle heads (23-26). The digital printing press further includes a floating detector (22) and configured to detect an abnormality of the sheet, and a control device (28) configured to control an operation of the driving device (41). The control device (28) stops the driving device (41) when the floating detector (22) detects a floating portion. The control device (28) operates the driving device (41) based on the phase of the printing cylinder when the floating detector (22) detects the floating portion and when the driving device (41) stops after floating detection and moving the floating portion detected by the floating detector (22) to a predetermined confirmation position.

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.
