Abstract
A process and a device for producing a printing tool in which a mask for sectional chemical passivation is applied to the surface of a workpiece that is to be subjected to a chemical surface working. In accordance with one embodiment, the process for producing a printing tool includes the steps of providing a workpiece having a surface which is subjected to a chemical surface working and spot spraying the surface of the workpiece section-by-section with a mask for sectional chemical passivation where the mask is essentially a wax and is sprayed onto the surface of the workpiece by a plurality of nozzles that are controlled with EDP support.

A process for producing a printing tool comprising the steps of:
- providing a workpiece having a surface which is subjected to a chemical surface working;
- forming a mask for sectional chemical passivation by spot spraying said surface of said workpiece, section-by-section, with a wax;
- and
- performing chemical surface working on areas of said surface of the workpiece left exposed by said mask so as to form a printing tool with a pattern set by said mask;
- wherein said wax is sprayed onto said surface of said workpiece by a plurality of nozzles that are controlled with EDP support.
A process for producing a printing tool comprising the steps of:
- providing a workpiece having a surface which is subjected to a chemical surface working;
- and
- spot spraying said surface of said workpiece, section-by-section, with a material which forms a mask for sectional chemical passivation;
- wherein a wax is sprayed onto said surface of said workpiece by a plurality of nozzles that are controlled with EDP support as the material which forms said mask;
- and
- wherein said nozzles are arranged next to one another in a direction of an X-axis and are combined functionally into groups of at least one nozzle, said process further comprising the steps of:
- moving at least one of said workpiece and said nozzles relative to one another in a direction of a Y-axis,
- chemical surface working said workpiece in the direction of the Y-axis;
- and
- moving at least one of said nozzles and said workpiece relative to one another in a direction of the X-axis to a new position with reference to the X-axis;
- wherein relative movement of said nozzles and said workpiece in a direction of the X-axis is a step width movement corresponding to a group width offset by a distance of adjacent nozzles divided by the number of said groups.
