Abstract
In a method to produce a printing form for rotogravure, in particular for heliorotogravure, a surface of the formis provided with a wear-resistant layer and the surface is provided with cups. Furthermore, a printing form is provided whereby the surface of the printing form comprises a wear-resistant layer in which the cups, with regard to their depth, are at least partially provided therein. The printing form may be used in a printing device for heliorotogravure.
