Abstract

Abstract The invention relates to a thermal engraving press for hot stamping, especially--although not exclusively--a plastic material which simulates engraved metal. A hot die and a movable platen are horizontally displaced from each other to support a work piece in a position opposing the die. The position of the work piece may be adjusted in three dimensions relative to the die. The hot stamping foil also provides a guard which prevents the operator from accidently touching the hot die. A feature of the inventive press is that it has an extremely low cost and is practically foolproof.
