Abstract
The invention is directed to a method for grinding a printing form in the area of flexographic or relief printing wherein the material to be ground is an elastomer material or an elastomer-containing material. A feed or first speed (v) is imparted to the material to be ground. The material is grindingly abraded with a grinding belt or grinding paper moving at a second speed (V) at least five times greater than the first speed (v).
Claims9
A method for grinding a printing form for use in flexographic or relief printing wherein the material to be ground is an elastomer material or an elastomer-containing material, the method comprising the steps of:
- providing said material to be ground and imparting a feed or first speed (v) thereto;
- determining an angular setting (α) based on a hardness of said material;
- said angular setting (α) defining an angle at which a grinding belt or a grinding paper dips into said material;
- and,
- grindlingly abrading said material at the angular setting (α) with the grinding belt or the grinding paper moving at a second speed (V) at least five times greater than said first speed (v) of said material to be ground.

- providing said material to be ground and imparting a feed or first speed (v) thereto;
- and,
- grindlingly abrading said material with a grinding belt or a grinding paper moving at a second speed (V) at least five times greater than said first speed (v),
- wherein:
- the grinding is carried out with a first step and a second step;
- the speed (V) of the grinding belt or the grinding paper is greater in the first step than in the second step;
- and/or,
- the roughness of the grinding belt or grinding paper is greater in the first step than in the second step.
