Abstract
Identification plates are produced by applying retroreflective material upon a male die member and subsequently pressing a plate blank over the retroreflective material to adhere the material to the blank. The blank is then lifted from the male die member and the retroreflective material, in the form of characters to be formed upon the identification plate, has pressure applied thereto to remove air bubbles. The blank is then replaced on the male die member which is formed with male die elements also in the form of the characters to be produced, and by applying a compressive force to the plate blank, an identification plate is formed with indented retroreflective characters devoid of air bubbles or the like. When replacing the plate blank on the male die member after application of pressure to the retroreflective material to remove the air bubbles, the device operates to insure accurate realignment between the retroreflective characters and the male die elements forming the indentations in the form of the characters in the identification plate.
