Abstract
The intaglio printing machine comprises a main structure (6), a plate cylinder (4), an impression cylinder (3), a wiping device (10) and an inking system consisting of a collector inking cylinder (5), of at least four color-selector cylinders (7a to 7d), and of an inking device (8a to 8d) associated with each color-selector cylinder (7a to 7d) and mounted in a mobile inking carriage (9). The ratio between the diameter of the collector inking cylinder (5) and the diameter of the plate cylinder (4) is equal to 2/3. The two extreme color-selector cylinders (7a, 7d) are placed so that they are approximately diametrically opposed with respect to the collector inking cylinder (5). The lateral walls of the inking carriage (9), on the same side as the color-selector cylinders, each comprise a recess (15) which is dimensioned in such a way that when the inking carriage (9) is in the working position, the color-selector cylinders (7b, 7c) which are between said two extreme color-selector cylinders (7a, 7d) lie wholly in the space defined by said recess (15).
