A pad-type printing machine with a mount for a cliche, with an ink supply device exhibiting a hollow body, whereby during the operation of the machine the end face of the hollow body rests at least occasionally on the cliche, with a device for pressing the end face of the hollow body against the cliche, with a device for producing a relative motion between the cliche and the hollow body, whereby the hollow body is guided such that it can swivel about an axis extending basically parallel to the relative motion, and with a pad which can be pressed onto the inked cliche and which accepts the ink from the recesses in the cliche and transfers it onto an object to be printed is characterized by the fact that at least on some of the circumference of its end face the hollow body comprises hard material and is microfinished with a peak-to-valley height of at most 2 .mu.m whereby the device for pressing the hollow body against the cliche is designed such that the contact force acts in the immediate vicinity of the contact surface between the cliche and the hollow body and is at least approximately uniformly distributed over the circumference of the end face, whereby the hollow body is guided such that it can additionally swivel about an axis extending transversely to the relative motion between the cliche and the hollow body. This permits a high working speed with only little outlay on maintenance. (FIG. 1).
A pad-type printing machine having a mount and a cliche, ink means exhibiting a hollow body mounted thereon, whereby during the operation of the machine the end face of the hollow body rests at least occasionally on the cliche, pressing means for pressing the end face of the hollow body against the cliche, motion means for producing a relative motion between the cliche and the hollow body, whereby the hollow body is guided such that it can swivel about an axis extending basically parallel to the relative motion, and pad means adapted to be pressed onto the inked cliche and which accepts the ink from the recesses in the cliche and transfers it onto an object to be printed, wherein at least on some of the circumference of its end face (96) the hollow body (64, 64a, 164, 264, 202) exhibits hard material and is microfinished with a peak-to-valley height of at most 2 .mu.m whereby the pressing means (84, 88, 188, 238, 246) for pressing the hollow body against the cliche (30) is designed such that the contact force acts in the immediate vicinity of the contact surface between the cliche and the hollow body and is at least approximately uniformly distributed over the circumference of the end face, whereby the hollow body is guided such that it can additionally swivel about an axis extending transversely to the relative motion between the cliche and the hollow body,
