The invention relates to a method (100) for producing an image structure (12) according to an image specification (20), in particular for a letterpress process and/or intaglio printing process, characterized in that the following steps are carried out: a) providing a base (10) for receiving the image structure (12), b) producing an image structure (12) on the base (10) so that an image layer (11) is formed on the base (10) by means of the image structure (12).

Provides is a seal surface carving apparatus capable of carving a seal surface using only a single attachment irrespective of a size of a stamp. A porous impression die having a seal surface to be carved is set on a dedicated attachment, and is loaded in a seal surface carving apparatus. A fitting projection fit to a bottom portion of the impression die is formed on the attachment, and impression dice having various sizes may be set. In addition, a slit hole extending in a conveyance direction is formed in an impression die setting portion of the attachment. Impression die size determination means of the seal surface carving apparatus determines a size of the impression die by detecting a position at which the impression die blocks the slit hole.

An intaglio printing plate is configured to protect a micro optics, RFID or chip feature of a security document during the process of intaglio printing the security document which applies very high pressure that could otherwise damage the micro optics, RFID or chip feature. A method for making the printing plate is also provided. The printing plate comprises a pressure relief depression located to coincide with the micro optics, RFID or chip feature during printing of a substrate of the security document. The pressure relief depression has a depth between 30-120 microns and shape corresponding to the shape of the micro optics, RFID or chip feature.

A method for fabricating a flexographic printing plate for printing image patterns including one or more uniform image regions includes defining a repeating tile having a plurality of different feature shapes positioned in a pattern of pseudo-random feature locations. A plate formation pattern corresponding to the image pattern is determined wherein the repeating tile is applied in a tiled arrangement to the uniform image regions. The plate formation pattern is used to form a flexographic printing plate, wherein regions of the flexographic printing plate corresponding to the uniform image regions of the image pattern include a pattern of raised features in positions corresponding to the feature positions in the repeating tile.
