Abstract
A process for producing a printing form includes forming a multiplicity of blind holes opening into a surface of a spatial or three-dimensional structure of the printing form, the blind holes serving for receiving a medium therein, and providing a propellant in the printing form for assisting in expelling the medium from the blind holes. A printing form produced by the process is also provided.
Claims32
A process for producing a printing form, which comprises:
- forming a multiplicity of blind holes opening into a surface of a spatial or three-dimensional structure of the printing form, the blind holes serving for receiving a medium therein;
- providing a propellant in the printing form for assisting in expelling the medium from the blind holes;
- providing as starting material for the spatial or three-dimensional structure a semifinished product having an ink-repellant property at the surface thereof;
- and
- embossing the blind holes in the semifinished product using an embossing mold.

- forming a multiplicity of blind holes opening into a surface of a spatial or three-dimensional structure of the printing form, the blind holes serving for receiving a medium therein;
- providing a propellant in the printing form for assisting in expelling the medium from the blind holes;
- providing an injection mold for forming the blind holes;
- filling the mold with a substance selected from the group consisting of a heated powder, a heated granulate, and a powder mixed with a binder, for molding the printing form;
- and
- opening the mold for releasing the thus molded printing form therefrom.
3 more elements
A printing form, comprising:
- a spatial structure having a surface with a multiplicity of blind holes opening into the printing form;
- a propellant disposed within said blind holes for permitting a temperature change in at least one medium located within the blind holes;
- said spatial structure being an assembly of a first and a second partial form, said first partial form being formed with through holes which, at ends thereof facing towards said second partial form, meet subareas provided with the propellant.
