Abstract

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).

First claim

We claim:

1. A method for the production of a 3D image structure according to a print image specification,
wherein
the subsequent steps are performed:
a) provision of a base body for the acceptance of an image structure,
b) generation of a 3D image structure on the base body such that a print image layer is configured with the 3D image structure on the base body, wherein the 3D image structure is additively generated by a printing form machine, wherein the 3D image structure is configured layer by layer to the base body, wherein according to step b) the image structure is generated in the printing form machine, wherein a carrier layer is additively generated by the printing form machine and the carrier layer is configured with the print image layer to the base body, and wherein the print image layer comprises a lower hardness than the carrier layer in order to ensure an optimal contact pressure during a printing process.

2. The method according to claim 1 ,
wherein
according to step b) initially a material is applied to the base body and subsequently is adapted such that the 3D image structure results.

3. The method according to claim 1 ,
wherein
according to step a) at least a removal or cleaning process is performed.

4. The method according to claim 1 ,
wherein
subsequent to step b) a post-processing of the 3D image structure occurs.

5. The method according to claim 1 ,
wherein
at least an elastic layer is generated by the printing form machine and at least the elastic layer is applied with the print image layer to the base body.
