1 gen 1829 anni - Embossed Printing - 1829 Louis Braille.

Descrizione:

This printing method was developed in the early 18th century by Louis Braille creating a universal language which is used frequently today to support social aims in making a language in which the blind can use. Braille is made through pressing dots in a certain order to make a pattern which exploits the sense of touch to translate or communicate something to a blind person. Due to it just using a series of dots also keeps the process relatively cheap
