ABSTRACT:
The method (10) of the present invention includes a first step of designing an image to be reproduced by the stamp pad (12). A pre-inked rubber material (14) derived from an ink and plasticizer premix is then super-cooled to immobilize the ink constituents (28) and harden the pre-inked material (14). A controller (52) then processes the information communicated from the computer (50) in order to control the operation of an engraver (54) such as a laser beam generator or a pantograph. The engraved material (12) is then warmed to room temperature and affixed to an appropriate handle. Alternatively, the selected image (38) is accomplished on the top surface of the stamp pad (12) during the curing procedure. In this procedure, the premix material (22) is heated from the bottom surface (30) to a curing temperature up to a selected height. A heat source (62) is applied to the image surface (18) such as to raise the material directly below to an appropriate curing temperature level to a selected depth.
