Beschreibung
Zusammenfassung:	The present invention provides an apparatus for producing patterns on a surface (18) of a substrate (12) The apparatus includes a rigid support member (14) such as a rigid tubular structure having first and second opposed ends and a fluid flow passageway extending therethrough. A printing stamp (16) is attached at one of the opposed ends of the rigid support member (14) The printing stamp (16) has a flexible diaphragm portion (20) which has an outer surface which is coated with one or more materials in a pre-selected pattern A pneumatic pressurizing mechanism communicating with an inner surface of the flexible diaphragm portion (20) through the fluid flow passageway is used to bias the flexible diaphragm portion outwardly into intimate and substantially uniform contact with the surface (18) of the substrate (12) for transferring the pre - selected pattern onto said surface. The rigid tubular supports (14) are attached to a robotic positioning mechanism for providing control of positioning of the stamp (16) relative to the substrate surface (18).
