Process of manufacturing embossed signage for handicapped individuals

A process for producing signage having a message-defining image that can be read by sighted individuals and a series of dots presenting a corresponding encoded message in Braille characters that can be touch deciphered by visually impaired persons, said process including the steps of:

• providing a master female mold having a surface including grooves therein presenting said visually observable message and a series of indentations defining a corresponding message in said Braille characters;
• depositing a layer of a flowable synthetic resin composition on said surface of the master female mold in filling relationship to said grooves and indentations,
• said composition possessing the property of becoming a solid mass upon application of elevated heat and pressure relative to ambient conditions;
• placing a backing member over said surface of the master mold in covering relationship to said flowable layer of the synthetic resin composition, said backing member being formed of an at least partially cured epoxy resin composite;
• laying a pressure-compensating element over the backing member, the pressure compensating element being flexible and compressible relative to the backing member;
• applying sufficient pressure and supplying adequate heat to the mold with the backing member and element thereon for a time period to effect conversion of the composition into a solid while at the same time expressing the composition from the space between the mold and said backing member except for the material in said grooves and indentations;
• causing said quantity of material in said grooves and indentations to adhere to the adjacent portions of the backing member;
• and
• thereafter removing the backing member with the message-defining solid composition firmly adhering thereto from between the mold and said element.
