PROCESS OF PRODUCING TACTILE DOTS, TACTILE DOT GROUPS, AND TACTILE IDENTIFIER MARKS

摘要

Techniques are described for the production of tactile dots, tactile dot groups, and tactile identifier marks on substrates that are tactilely recognizable by visually impaired individuals. Each tactile dot can be formed individually in the substrate, for example by separately embossing each tactile dot using a single punch and die pair. By using a single punch and die pair, the size, complexity and cost of the tactile dot embossing mechanism can be reduced, and the spacing between the tactile dots can be varied.

1. A process of forming a tactile dot group in a substrate, the tactile dot group having two or more tactile dots arranged to form a tactilely recognizable character, comprising:
embossing a first one of the tactile dots of the tactile dot group in a first column on the substrate; after the first tactile dot is formed, embossing a second one of the tactile dots of the tactile dot group in the first column on the substrate.
