A printing unit includes a support frame that is supported to face a transfer passage for a sheet; an inkjet head that is fixed to the support frame and performs printing on a printing surface of the sheet; drive bodies that are rotatably supported on the support frame on both sides of the inkjet head in a width direction of the sheet and come into contact with the printing surface of the sheet; and a drive device that drives and rotates the drive bodies.

A corrugated fiberboard printing device includes a protection device which regulates approaching of a corrugated fiberboard within a predetermined distance against an inkjet head, and a controller. The protection device includes multiple regulation devices which are juxtaposed in a width direction of the corrugated fiberboard, and a movement mechanism which moves each of the multiple regulation devices in the width direction. The controller includes a specific column setting unit which is set to classify a specific column, in which a printing quality is less influenced even when the specific column is regulated by the regulation device, with respect to the corrugated fiberboard in a sheet width direction based on order information, and a movement mechanism control unit which controls the operation of the movement mechanism and moves each of the regulation devices so as to regulate the corrugated fiberboard in the specific column.

A printing device includes a rotatable printing cylinder, a blanket cylinder configured to make a synchronous rotation with the printing cylinder in contact with each other and to convey a printing medium by nipping the printing medium with the printing cylinder, an inkjet head that forms an image on a surface of the blanket cylinder by squirting heatset ink onto the surface of the blanket cylinder, and a first heating unit that heats up either the printing medium conveyed into a contact portion of the printing cylinder and the blanket cylinder or the blanket cylinder.

Printing device, printing method, sheet-fed printing press, and rotary printing press

In a printing press, it is configured such that a newspaper web offset printing press is composed by a feeder device, a printing device, a guiding device, a turn bar device, and a folding unit; as a guiding device, there are provided an upstream side guide roller and a downstream side guide roller which are disposed with a predetermined interval along a transportation direction of a web for guiding transportation of the web; and there is disposed an ink-jet printer for performing digital printing on the web guided between the guide rollers. By setting diameters of the upstream side guide roller and the downstream side guide roller to different values, vibration of the print medium which is transported while being guided by the guide rollers is suppressed, and the print quality is thereby improved.

Printing press

In a printing press and a method, provided are an offset rotary press for printing predetermined information on a web using a printing plate, a printer for digitally printing specific information desired by a reader and reader identification information at a specific location on a web surface, and a dispatch system for reading the reader identification information on a newspaper, thereby sorting the newspaper by delivery destination. The offset rotary press and the printer are collectively driven by a controller, thereby improving the productivity of printed matter.
