| 101 | Intaglio printing machine with direct and color-collect inking | US23216 | 1993-02-25 | US5282417A | 1994-02-01 | Albrecht J. Germann |
| The intaglio printing machine has three machine stands (I, II, III). Essentially, the impression cylinder (1) and the plate cylinder (2) are mounted in the first stand (I), the stencil rollers (10) and the inking unit (11) are mounted in the second stand (II), and the color-collect cylinder (8) is mounted in the third stand (III). The third stand (III) is adjustable in such a way that it can be removed from the space between the first and second stands and brought into an inoperative position, so that it is possible to bring the second stand (II) up against the first stand (I) to form an intaglio printing machine with direct inking. This results in a convertible intaglio printing machine by means of which a collect intaglio print can be made in a first operating position, in which all three stands assume their working position, and a direct intaglio print can be made in a second operating position, with the use of only the first and second stands. | ||||||

| The present invention consists of a combined offset and flexographic printing apparatus. The preferred embodiment of the present invention provides apparatus for printing both quasi-random numbers and a plurality of different images on cylindrical objects. In this preferred embodiment, the invention consists of a cylindrical container printing and decorating press incorporating a blanket cylinder with a plurality of peripheral segments on which rubber offset blankets are mounted. A random number printing unit and a polygonal multi-image printing unit are provided between two segments of the blanket cylinder. Preferably, a plurality of random number/multi-image printing unit pairs are provided, one located between each pair of adjacent segments. A plurality of printing stations are arranged around the blanket cylinder, each featuring a master plate for transferring a single color image to the printing faces of the offset blankets, the random number printing units and the hexagonal multi-image printing units. The portion of the image transferred to the printing face of the offset blankets consists of the actual design being transferred to the printed objects. The resultant image transferred from the blanket cylinder to the object being printed is a combination of a pure offset image printed by the offset blankets of the printing cylinder together with flexographic images printed by the printing faces of the random number and hexagonal multi-image printing units. | ||||||
| 104 | Method and apparatus for dry offset intaglio printing | US58686 | 1987-06-04 | US4942813A | 1990-07-24 | Shigeji Arai |
| An intaglio cylinder for effecting intaglio printing is disposed in contact with an impression cylinder and a blanket cylinder for effecting dry offset printing is disposed in contact with the intaglio cylinder. These cylinders are disposed such that a line interconnecting the axes of the impression cylinder and the intaglio cylinder will make an angle of about 90.degree. with respect to a line interconnecting the axes of the intaglio cylinder and the blanket cylinder. When printing with the printing press described above a method is used comprising the steps of forming an intaglio image on the intaglio cylinder, forming a dry offset image on the blanket cylinder, transferring the dry offset image on the blanket cylinder onto non-image portions of the intaglio cylinder, and simultaneously transferring the dry offset image and the intaglio image on the intaglio cylinder onto a sheet wrapped about the impression cylinder. | ||||||

| 107 | Multi-printing mode rotary printing machine | US360065 | 1982-03-22 | US4397235A | 1983-08-09 | Hermann Fischer |
| To permit, in addition to selectively raised letter printing or direct lithographic printing on a single plate cylinder (2), additionally flexo printing, the damping system (4) utilized for direct lithographic printing is filled with flexo printing ink rather than with damping liquid, and the direction of rotation of the plate cylinder, and an associated impression cylinder, together with direction of passage of a printed web or sheet (28) is reversed so that flexo printing ink is applied by the damper, positioned in advance of the printing or impression line (29) to a flexo printing plate on the plate cylinder (2) whereas, for direct lithographic printing, damping liquid is first applied to the plate cylinder for subsequent application of ink by an inker (8) in engagement with the plate cylinder which is removable from engagement when used in flexo printing. The roller brush (20) is positioned between the damping system (4) and the inker (3), engaged with the flexo printing plate for flexo printing, but out of contact with the plate cylinder for direct lithographic printing. For raised letter printing, the damper application roller (12) is disconnected from contact with the plate cylinder, and the roller brush (20) operating in the differential speed with respect to the plate cylinder, is used to clean the raised portions of the printing plate thereon. The system permits extension of existing selective DiLitho or raised letter printing also to flexo printing. | ||||||
