ABSTRACT:
A method for producing embossed designs on work surfaces such as on molds, rolls or dies. A photomechanically imageable transfer material is exposed to the design to be embossed. The material is developed and the acid resistant design material remaining on a backing sheet is mechanically transferred to the work surface by burnishing the back of the backing sheet. The surface is then etched and the acid resistant design elements removed so that the embossed work surface is ready for use.
