摘要

Improvements in the systems of machining surfaces for obtaining prints, essentially characterized by the fact of obtaining a matrix or template, of suitable material, in which an integral cut is made of the silhouette of the motive to be reproduced; by arranging said matrix or template on the surface of the material to be treated, preferably a crystal, associating thereto optionally through conventional means that guarantee the stable unión of both elements during the phases of the process.
