1. A method comprising:
- receiving design data specifying a design to be embossed;
performing a plurality of times;
selectively discharging a precharged electrostatic drum of a printing device in accordance with the design to be embossed, which forms a latent image on the electrostatic drum corresponding to the design to be embossed;
applying ink to discharged portions of the electrostatic drum that form the latent image corresponding to the design to be embossed; and
transferring the applied ink from discharged portions of the electrostatic drum to an impression cylinder of the printing device via an intermediary cylinder of the printing device, which forms an embossing die on the impression cylinder as multiple ink layers constituting a printed relief pattern in accordance with the design data;
after forming the embossing die, advancing a medium between the intermediary cylinder and the impression cylinder, the embossing die embossing the design onto the medium; and
while the medium is advancing between the intermediary cylinder and the impression cylinder, printing an image on the medium via the intermediary cylinder using ink.

Abstract
An embossing die is created by printing multiple ink layers (530, 540) in superposition thereby to build up a printed relief pattern (510) in accordance with received design data specifying a design to be embossed. The design data is modified after receipt to introduce into the printed relief pattern to be built, one or more channels (610) which extend depth-wise through multiple ink layers of the printed relief pattern (510) and serve to fully or partially segment the printed relief pattern.

13. An apparatus comprising:
-
an electrostatic drum that is chargeable and selectively dischargeable, and that is receptive to application of ink on discharged portions thereof; an intermediary cylinder; an impression cylinder to receive ink from discharged portions of the electrostatic drum via the intermediary cylinder; a data processing arrangement to; receive design data specifying a design to be embossed; perform a plurality of times; precharge the electrostatic drum; selectively discharge the electrostatic drum in accordance with the design to be embossed, which forms a latent image on the electrostatic drum corresponding to the design to be embossed; apply the ink to discharged portions of the electrostatic drum that form the latent image corresponding to the design to be embossed; and transfer the applied ink from the discharged portions of the electrostatic drum to the impression cylinder via the intermediary cylinder, which forms an embossing die on the impression cylinder as multiple ink layers constituting a printed relief pattern in accordance with the design data; after forming the embossing die, advance a medium between the intermediary cylinder and the impression cylinder, the embossing die embossing the design onto the medium; and while the medium is advancing between the intermediary cylinder and the impression cylinder, printing an image on the medium via the intermediary cylinder using ink. - View Dependent Claims (14, 15, 16, 17)
