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.
An intaglio printing machine having a plate cylinder (2) carrying at least one printing plate, an impression cylinder (1) cooperating with said plate cylinder (2), a wiping device (3) cooperating with the plate cylinder, a color-collect cylinder (8), stencil rollers (10) and inking units (11) inking these stencil rollers, the plate cylinder, impression cylinder and wiping device being mounted in a first machine stand (I), wherein the stencil rollers (10) and their inking units (11) are mounted in a second machine stand (II) which is adjustable in a direction oriented perpendicularly to the roller axes, wherein the color-collect cylinder (8) is mounted in a third machine stand (III) which can be removed from the space between the first and second machine stands, and adjusted into an inoperative position, and wherein the second machine stand (II) is designed, in a first operating position in which the color-collect cylinder (8) bears on the plate cylinder (2), to ink this color-collect cylinder (8) with its stencil rollers (10) and, in a second operating position in which the third machine stand (III) is located in said inoperative position, to ink the plate cylinder (2) with its stencil rollers (10).
