The invention describes a system (1) for overprinting on formats, comprising at least one printing unit (2), having first actuation means (14), and also comprising format supplying means (6, 7), format collecting means (9), at least one conveyor belt (5), second actuation means (10), and control means (11, 12, 13). The at least one printing unit (2) comprises at least one rotatable printing cylinder (3), having printing zones at the surface, and also first actuation means (14), configured to drive, in a controllable manner, the rotation of the printing cylinder (3). The format supplying means (6, 7) are configured to supply the system with one or more formats (4), each being intended to be overprinted in preset zones to be overprinted. The format collecting means (9) are configured to collect the one or more formats (8) once printed. The at least one conveyor belt (5) is configured to arrange, for the aforementioned one or more formats (4), an advancement path comprised between the format supplying means (6, 7) and the format collecting means (9). The advancement path passes through the printing unit (2). The second actuation means (10) are configured to drive, in a controllable manner, the advancement of the conveyor belt (4) along the advancement path, upstream of the printing unit (2) in the advancement direction. The control means (11, 12, 13) are configured to control, in a coordinated manner, both the first actuation means (14) and the second actuation means (10), so as to determine at each moment a correspondence of the preset zones to be overprinted of the format (4) with respective printing zones of the printing cylinder (3).

A marking machine for marking an article and a method of operating the same. The marking machine has a marking head including a support and at least one punch. The marking machine also includes a positioning system configured to position the article with respect to the punch. The punch has rotational mobility about an axis of rotation that is fixed with respect to the support.

An offset printing method is provided that, while using an ink with a viscosity that allows for printing of a print image on a printing plate by an ink-jet process, enables a precise print image to be transferred from the printing plate to a print medium by use of a printing blanket. The offset printing method includes a printing-plate making step of printing an inked image on a printing plate by an ink-jet process, an ink drying step of evaporating a solvent contained in the ink of the inked image to increase the viscosity of the ink, a transferring step of transferring the inked image to the surface of a printing blanket, and a printing step of pressing the printing blanket against a print medium.

A method of producing a printed substrate includes rotating an anilox roll having first recesses supplied with a coating liquid, rotating a plate cylinder fitted with a printing plate having second recesses, transferring the coating liquid from the first recesses to the second recesses and holding the coating liquid in the second recesses, and rotating the plate cylinder while keeping the outer surface of the printing plate in contact with a printed substrate to transfer the coating liquid held in the second recesses to the printed substrate. A ratio of a maximum volume of the coating liquid held by the second recesses per unit area on the outer surface of the printing plate to a maximum volume of the coating liquid held by the first recesses per unit area on the outer surface of the anilox roll ranges from 0.50 to 2.00.

A doctor blade for spreading a coating solution supplied to a roll surface of an anilox roll rotatable about a rotation axis over the roll surface is in a longitudinal plate shape. The doctor blade includes a long edge and bent portions. The long edge is set against the roll surface of the anilox roll along the rotation axis. The bent portions are at ends of the long edge and at angles to the long edge.

A transfer plate and an orientation film generation system are provided. The transfer plate includes a bottom plate and a plurality of relief plates, wherein, the bottom plate is disposed on a printing cylinder and is distributed with a plurality of engagement holes, each of the engagement holes has a plurality of stopper locations configured to provide different engagement depths; and the plurality of relief plates and the plurality of engagement holes are disposed in one-to-one correspondence, and each of the relief plates is provided with an engagement pin cooperated with the stopper locations of a corresponding engagement hole, wherein the relief plate is made of permeable materials. The orientation film generation system includes the above transfer plate.

A transfer device and a coating machine are disclosed. The transfer device includes a transfer plate and a printing roller. A projection is formed on a first surface of the transfer plate; a first recess corresponding to the projection is formed on the printing roller; and when the transfer plate covers a surface of the printing roller, the projection and the first recess are matched with each other to fix the transfer plate with the printing roller. The transfer plate in the transfer device will not be subjected to extended deformation and sliding even under an action of external force during printing process, so that the production quality can be maximally guaranteed.

A flexographic printer is provided with: a printing plate for transferring ink at an ink transfer site to an object to be printed S; an anilox roll for supplying ink to the printing plate at an ink supply site; a plate cylinder on which the printing plate is wound and rotated; and an ink solvent supply unit for supplying a solvent for the ink on the surface of the printing plate in a post-ink transfer region that is downstream of the ink transfer site in the plate cylinder rotation direction and upstream of the ink supply site in the plate cylinder rotation direction.
